Item 1. Business.
     General

 Structural  Dynamics Research Corporation  (the  "Company"  or
 "SDRC")  is a leading international supplier of mechanical  design
 automation  ("MDA")  software,  product  data  management  ("PDM")
 software and related services within the mechanical computer-aided
 design,  manufacturing  and engineering ("CAD/CAM/CAE")  industry.
 The Company's mission is to provide software tools and services to
 significantly   enhance  SDRC's  customers'   mechanical   product
 development and engineering processes.

 The  Company's software and services provide customers with  a
 fully  integrated solution for a concurrent engineering design  to
 manufacturing  life cycle.  The Company's principal  MDA  software
 product,  I-DEAS  Master  Series(TM), is  a  world-class, 
integrated  CAD/CAM/CAE  solution  which  allows  manufacturers  to 
 optimize product performance and reduce cost while streamlining the
product  development  process.  The Company has  recently  released 
a  new product,  I-DEAS Artisan Series(TM), that is an MDA product
aimed  at the  mid-level  CAD/CAM/CAE market. SDRC's PDM product, 
Metaphase Series 2 software, provides a comprehensive enterprise
approach to the  management and control of product information,
configuration, release management and work flow.

     Background

The  Company was incorporated under the laws of the  State  of
Ohio  in  1967.  The  Company  was  founded  to  provide  advanced
engineering  consulting services and over time developed  some  of
the  industry's first mechanical engineering software packages  to
assist in its consulting efforts.  After receiving strong customer
interest  in these software packages, the Company began  marketing
its  software  in the early 1970s.  Today, SDRC's  combination  of
software  technology  and  related software  services  provides  a
comprehensive solution to address customer needs.

During  the  past  five  years, the Company  has  restructured
certain  aspects  of its business.  In January  1997  the  Company
acquired  the  remaining  stock  of  Metaphase  Technology,   Inc.
("Metaphase")  and certain assets of Control Data Systems,  Inc.'s
global  PDM  software  sales and support business.   In  1992  the
Company and Control Data Systems, Inc. established Metaphase as  a
joint venture Company to develop product data management software.

In  June  1996 the Company completed the acquisition of  Camax
Manufacturing  Technologies, Inc. ("Camax") and its  wholly  owned
subsidiaries. Camax provided computer-aided manufacturing software
for computerized numerical control machining operations.

In  1995 the Company purchased the remaining interest of  SDRC
Software and Services GmbH ("SDRC GmbH").  In 1994 the Company and
Siemens  Nixdorf Informationssysteme AG formed the joint  venture,
SDRC  GmbH, to supply mechanical CAD/CAM/CAE software and services
in  Central Europe.  Also in 1995, the Company merged its software
products  marketing and engineering services subsidiaries  into  a
single  subsidiary which now provides both software  products  and
related services.

Strategy

The Company's strategy is to provide world-class software  and
engineering  process implementation expertise  to  help  customers
improve  their  mechanical  product  development  and  engineering
processes.   SDRC's  customers tend  to  be  product  and  process
innovators  who  develop an effective long-term relationship  with
SDRC.  In addition to the establishment of these relationships  at
the  high  end,  SDRC is also broadening its reach into  the  less
service-intensive tiers of the CAD/CAM/CAE market.

I-DEAS Product Suite

The Company develops, markets and supports a comprehensive MDA
software  product  called I-DEAS ("Integrated  Design  Engineering
Analysis  Software")  Master Series  and  a  mid  priced  software
product  called  I-DEAS Artisan Series.  I-DEAS(TM)  software 
allows engineers  to  design,  simulate,  test  and  manufacture 
product concepts  in  a fraction of the time required using
standalone  or partially integrated software tools.  As a result,
the software is a  tool  to assist customers in developing higher
quality products faster,  at  a  lower cost, and delivering to the
market  in  less time.   The I-DEAS software is specifically
designed and optimized to  meet the needs of engineers who design
products by using solid modeling technology.  With the easy to learn
user interface, users are   able  to  create  and  view  a  "master 
model,"   a   solid representation  of a product that precisely
defines  its  geometry and material characteristics.

I-DEAS Master Series software allows product development  team
members  to  work  concurrently on the same project  sharing  this
common  master  model.  This master model is easily understood  by
everyone  concerned  with  the product, including  representatives
from  management, marketing and manufacturing.  It can be analyzed
to evaluate the mechanical performance and structural integrity of
the design concept, as well as to provide information that can  be
used to optimize product performance, study assembly sequences and
assess "manufacturability".

Artisan Series was specifically created to address the growing
mid  price  CAD  market.    Artisan  provides  high  level  design
functionality  to  smaller  design  groups  and  companies   while
ensuring  upward data compatibility and user migration  to  I-DEAS
Master Series.

Metaphase Series 2

SDRC also develops, markets, implements and supports Metaphase
Series  2,  product data management software, which helps  create,
manage and control data associated with product information as  it
evolves through the product life cycle.   Metaphase Series 2 is  a
modular  PDM system designed to provide the depth and  breadth  of
functionality  customers require to meet current and  future  data
management needs.

Metaphase  Series 2 software helps customers improve  the  way
they create, share, access, define and support their product data.
For  product developers, this means fast, reliable access  to  the
latest drawings, specifications and engineering changes they  need
regardless of location or the application used to create them. And
for  managers, it means accurate, reliable information about work-
in-process  as  well as documentation of the entire  product  life
cycle.   Metaphase  Series  2  is  compatible  with  client/server
environments with distributed design and engineering departments.

Services

The  Company  provides customers with process  automation  and
implementation services as well as technical applications software
support,  maintenance  and training.  Building  on  its  extensive
knowledge   of   mechanical  design  automation   technology   and
engineering  applications  and processes,  the  Company  offers  a
"total  solution"  by  providing process automation  and  software
implementation  services for I-DEAS and PDM software.  Engineering
consulting  services assist in the optimization of the  customers'
product   design   and  in  the  improvement  of  the   customers'
development process.  In addition, advanced training and knowledge
transfer are provided to customers to enable them to integrate and
optimize   their   MDA  and  PDM  investment.  Advanced   computer
simulation methods and in-depth application expertise are utilized
for   traditional  or  highly  specialized  computer  technologies
including  design  audits,  product  design,  troubleshooting  and
engineering process design.


Technical applications software support and maintenance service
provides  telephone  "hotline" support  and  software  maintenance
corrections   for   licensed  products  and   features.   Software
enhancement  versions are also released during  the  term  of  the
contract  with documentation updates.  In addition, other services
are  provided  that  enhance and maintain the customer's  software
investment.

The  Company  provides basic training for each major  software
package.   Advanced  training classes  are  offered  for  selected
applications to support continued growth of customer skills and to
increase the productivity of those who utilize SDRC software.

Heterogeneous Environment/Platforms

The Company's software is available on the leading engineering
workstations.   This  hardware platform  independence  allows  the
Company's  customers  to  operate in a heterogeneous  environment,
selecting  and  adding  software modules  for  a  broad  range  of
hardware  systems  based  upon  their  unique  requirements.   The
productivity  benefits  of  leading-edge  capabilities,  such   as
unprecedented ease-of-use, team-oriented product development, best-
in-class    design,   performance   simulation   and    integrated
applications, have increased the number of potential users who can
utilize  these  tools.   The  Company believes  its  products  and
services  are  of great value to companies which must  accelerate,
improve  and streamline design processes in response to  increased
competition   while  simultaneously  designing  and  manufacturing
mechanical products in accordance with specific quality  and  cost
criteria.   A  broad  range of industries are potential  users  of
these  tools,  with  the highest concentration  of  users  in  the
automotive,   consumer  and  industrial  electronics,   industrial
machinery and aerospace industries.

Sales Channels

The Company markets its products and services primarily through
a  worldwide direct sales and support force.  The Company  employs
highly skilled engineers and technically proficient support people
capable  of  serving the sophisticated needs of the customer.  The
Company also has an established relationship with a distributor in
Japan,  Information  Services International - Dentsu  Ltd.,  which
accounted  for  approximately 12%, 13% and 10%  of  the  Company's
consolidated  revenues  in 1996, 1995 and 1994,  respectively.  In
addition,  the  Company  also utilizes  distributors,  value-added
resellers  and  other marketing representatives for its  marketing
efforts.

In certain markets where the Company does not maintain a direct
sales   force,  it  licenses  its  products  through   independent
representatives.   Telemarketing is also used to  complement  both
the direct and indirect marketing channels.

Seasonality

Historically,   the   Company  has  tended   to   realize   a
disproportionate  amount  of its total  revenue  in  each  quarter
during   the  last  month  of  the  quarter,  and  to  realize   a
disproportionate  amount of its total annual  revenue  during  the
fourth  quarter of each year.  Future quarterly results  could  be
impacted by factors such as order deferrals, a slower growth  rate
in the market, increased competition or adverse changes in general
economic  conditions in any of the countries in which the  Company
does business.  Any shortfall in revenue or earnings could have an
immediate and significant adverse effect on the trading  price  of
the  Company's  stock  in  any  given  period.   The  results   of
operations  for  the three years ending December 31,1996  are  not
necessarily indicative of future expectations.

Competition

The  market  for  the Company's software  products  is  highly
competitive  and  the  Company  expects  competitive  pressure  to
increase in the future.  To maintain its position of technological
leadership,  the  Company must continually  enhance  its  existing
software  products and pursue the development and introduction  of
new products.

The Company competes against products in the CAD/CAM/CAE market
including  the  CATIA products marketed by IBM and  Dassault,  the
UNIGRAPHICS product marketed by EDS, the CADDS product marketed by
Computervision   Corporation,  the  I/EMS  product   marketed   by
Intergraph  Corporation and the Pro/ENGINEER product  marketed  by
Parametric Technology Corporation.  In the PDM market, the Company
competes against such products as the Optegra product marketed  by
Computervision Corporation, the Sherpa product marketed by  Sherpa
Corporation, the IBM Product Manager marketed by IBM  and  others.
The  Company's future success will depend in a large part  on  its
ability  to further penetrate its installed customer base as  well
as the installed customer base of its competitors.

The  principal competitive factors in the CAD/CAM/CAE and  PDM
market   for   software   and   related   services   are   product
functionality,   product   breadth   and   integration,    product
performance, product quality, hardware platform support,  ease  of
product  use,  price, customer support, technical  reputation  and
size  of installed customer base.  There can be no assurance  that
the  Company  will  be successful in developing or  marketing  new
products  or that any new products will adequately achieve  market
acceptance.  There can be no assurances that competition will  not
have  a  material  adverse  effect on  the  Company's  results  of
operations.


The Company's employees are an important component of the SDRC
"total solution" approach in providing MDA and PDM software  tools
and  related  engineering consulting services to  customers.   The
Company's  success will depend in part on its ability  to  attract
and retain employees who are in great demand.

Other Information

Segment and geographic information is included on page  53  of
the  Company's  Annual Report to Shareholders for the  year  ended
December  31,  1996,  which is incorporated herein  by  reference.
Revenue  from one customer represented 11% of consolidated revenue
in 1996.

The  Company owns all the standard software products  that  it
licenses  with  the  exception of I-DEAS  Drafting(TM),  I-DEAS 
View Markup(TM),  I-DEAS  Visualization Laboratory(TM), I-DEAS 
Assembly  Fly Through(TM),  I-DEAS Symbols Library(TM), I-DEAS
TMG(TM), I-DEAS Electronic     Systems Cooling(TM), portions of
I-DEAS Sound Quality(TM), the mechanism     analysis portion of    
I-DEAS Assembly Set, and a variety of    data  translators  which it
licenses from  third  parties.   Under     these  license
agreements, the Company pays a royalty to the third     parties.

As  is customary throughout the software industry, the Company
relies  both  on  copyrights  and trade  secrecy  for  proprietary
protection  of  its  software  products.   The  duration  of  such
protection  is  considered  to be adequate  given  the  constantly
changing  nature  of  the business. The Company  also  utilizes  a
number  of trademarks, both registered and otherwise, with respect
to   its  software  products.   The  proprietary  status  of   its
trademarks lasts indefinitely, as long as the trademarks remain in
use.

The  Company  typically ships product  within  30  days  after
acceptance of a customer purchase order and execution of a license
agreement.  A substantial portion of quarterly shipments  tend  to
be  made  in the last month of the quarter.  The Company does  not
believe  that backlog is indicative of potential revenue  for  any
future period.

Research  and  development expense amounted  to  approximately
$30,719,000,  $24,472,000, and $24,917,000   in  1996,  1995,  and
1994, respectively.

As  of  December  31,  1996, the Company had  1,604  full-time
employees,  of whom 371 were engaged in research and  development,
1,020 in sales, services support and marketing, and 213 in general
management and administration.  In addition, the Company  employed
33 part-time employees and cooperative students.

Item 3. Legal Proceedings.

     Securities Litigation and Related Matters

Except for the following matters, SDRC is not a party  to  any
litigation  other than ordinary routine litigation  incidental  to
its  business.  The Company was a defendant in a class action suit
alleging  violations of certain federal securities laws, captioned
In   Re:   Structural  Dynamics  Research  Corporation  Securities
Litigation,  United  States District Court, Southern  District  of
Ohio, Consolidated Master File No. C-1-94-630.   In December 1995,
the   parties  to  this  matter  entered  into  a  Memorandum   of
Understanding for settlement, subject to final Court approval.  On
March  22, 1996, the Court approved the proposed settlement and  a
final order was entered.  Pursuant to the order, a settlement fund
of $37.5 million was established, consisting of $17.6 million cash
provided  by the Company, $10.0 million in shares of the Company's
common  stock (to be valued-based on the market price at the  time
of  distribution), and $9.9 million cash provided by the Company's
former   accountants.  The  settlement  does  not  constitute   an
admission of liability on the part of any defendant. The Company's
Board of Directors determined that the settlement was in the  best
interest  of  the  Company and its shareholders in  light  of  the
uncertainty of the outcome, the high cost of continued litigation,
and  the  high  level  of management time and attention  continued
litigation would have required which could be better spent on  the
Company's business.

The Company was a party to shareholders' derivative litigation
captioned   In   Re:  Structural  Dynamics  Research   Corporation
Derivative  Litigation,  United States  District  Court,  Southern
District  of  Ohio, Consolidated Master File No. C-1-94-650.   The
Company   paid  the  plaintiffs'  counsel  fees  of  approximately
$900,000  and  $50,000 for their out-of-pocket  expenses  in  full
settlement of the matter.   The parties' agreement was approved by
the United States District Court on July 19, 1996.

Based  on  the same facts which gave rise to the Class  Action
Case   and  the  Derivative  Case,  the  Securities  and  Exchange
Commission  commenced a formal, private investigation of  SDRC  in
September  1994 which remains pending.  SDRC is fully  cooperating
with this investigation but cannot predict its outcome.

Pursuant  to certain contractual obligations, the Company  has
agreed  to  indemnify  its directors and  officers  under  certain
circumstances against claims arising from lawsuits.   The  Company
may  be  obligated  to  indemnify certain  of  its  directors  and
officers for the costs they may incur as a result of the lawsuits.

During  1995  and  1996  SDRC carried $5  million  of  primary
directors  and  officers  liability insurance  coverage  from  the
Federal  Insurance Company plus "excess liability  coverage"  from
Agricultural Excess and Surplus Insurance Company ("AESIC"), which
provides  $3  million  of such coverage,  and  from  Old  Republic
Insurance  Company ("Old Republic"), which provides an  additional
$2 million of such coverage.  The directors and officers liability
insurance, both primary and excess, is potentially available  with
respect  to the Class Action Case and the Derivative Case  because
certain  of  SDRC's  directors and former officers  were  personal
defendants in those matters. Coverage under the excess policies is
dependent  upon  first exhausting the primary coverage.  SDRC  has
come to an understanding with the primary insurer with respect  to
its  coverage,  but  the  excess  carriers  have  to  date  denied
coverage.   On  October  11, 1995, SDRC and certain  officers  and
directors  named  in the Class Action Case and/or  the  Derivative
Case  filed  a  declaratory  judgment action  against  the  excess
carriers   in   a  case  entitled  Structural  Dynamics   Research
Corporation,  et al. v. Agricultural Excess and Surplus  Insurance
Company,  et al., Clermont County Court of Common Pleas, Case  No.
95-CV-9697.   The  action  alleges  that  neither  AESIC  nor  Old
Republic is entitled to rescind its policy or exclude any  of  the
named plaintiffs from coverage with respect to claims in the Class
Action Case or the Derivative case.   AESIC and Old Republic  each
responded  and have taken the position that they are  entitled  to
rescission and that all claims are excluded under the terms of the
policy.   While SDRC intends to vigorously pursue this case, there
can be no assurance as to its ultimate outcome.

During 1993  and 1994, the Company's level of expenses increased  to
support technological development and to promote revenue growth.  
As anticipated  revenue  growth  did  not  materialize,  the  
Company's expenses exceeded revenue resulting in operating and net
losses.  In 1995,  the  anticipated cost of the class action lawsuit 
settlement, net  of estimated insurance proceeds, was included in
the results  of the operations.


Management's  Discussion  and Analysis  of  Financial  Condition 
and Results of Operations
Structural Dynamics Research Corporation



(in thousands)

The  Company  operates  in  a  single  industry  segment   providing
mechanical  design automation (MDA) software, product data
management (PDM)  software  and related services.  I-DEAS Master 
Series(R)  is  a world-class,    integrated   CAD/CAM/CAE   product 
  which    allows manufacturers to optimize product performance and
reduce cost,  while streamlining  the  product development process
from  concept  through manufacturing.    This   total  approach  to 
product   and   process engineering  enables  significant 
improvements  in  quality,   while reducing  overall  development
time and cost.   Metaphase  Series  2(R) software,  SDRC's PDM
product, provides a comprehensive  approach  to the  management and
control of product information and configuration, release 
management and work flow.  CAMAND(R) and Smart  CAM(R)  are  MDA
products used for generating, optimizing, simulating and verifying
NC programs  and  machine  tool motion for all types  of  CNC 
machining processes.


Revenue

Consolidated revenue, including licenses and services, for 1996 
rose to  $285,256 compared with 1995 revenue of $224,138 and 1994 
revenue of  $185,358.  This represents increases of 27% in 1996  and 
21%  in 1995.   The  growth is due to an increase in the Company's 
installed software  base  and the associated increase in
maintenance,  software services and training revenue.

Software  Licenses  Revenue.   Software  licenses  revenue  for 
1996 increased to $153,058 compared to 1995 revenue of $131,211  and 
1994 revenue of $115,051.  These amounts represent an increase of 
17%  in 1996  and  14%  in  1995 which is attributed to the
continued  market acceptance  of  the  I-DEAS  Master Series product 
enhancements  and significant  software  license  purchases  from 
a  large  automotive customer.  The Company expects continued growth
in software  licenses revenue.

Software Maintenance and Services Revenue.  Software maintenance 
and services  revenue  is  derived from software  maintenance 
contracts, software  services and training.  Combined software 
maintenance  and services  revenue increased to $132,198 in 1996 or
42% over 1995  and to  $92,927 in 1995 or 32% over 1994.   This
revenue represents  46%, 41%  and  38% of consolidated total revenue
in 1996, 1995  and  1994, respectively.   Software  maintenance 
growth  is  due  to  increased revenue  generated  from  maintenance 
contracts  for  both  new  and existing   customers.    Software 
services   growth   is   primarily attributable to the increased
level of I-DEAS and Metaphase Series 2 implementation and
integration projects.  In addition, the  Company's software 
services revenue was impacted favorably  by  a  significant contract 
from  one of its major automotive customers.   The  Company expects 
that  the  software maintenance and  services  revenue  will
continue to increase.

Geographic.   Total revenue from international operations  accounted
for  52%, 54% and 55% of consolidated total revenue in 1996, 1995
and 1994,  respectively.   In  1996, significant  increases  in 
domestic revenue from a major automotive customer and slower revenue
increases in  Asia-Pacific  resulted in declining international 
revenue  as  a percentage of total revenue.  In July 1995, the
Company purchased the remaining  shares  in  SDRC GmbH.  As of the 
acquisition  date,  the revenue  generated  by  SDRC GmbH was
included  in  the  consolidated financial  statements.  The Company
expects the international  market to continue to account for a
significant portion of total revenue.



Cost and Expenses

Cost  of Revenue.  Cost of revenue consists principally of the 
staff and  related  costs  associated with the generation  and 
support  of software  services  revenue,  amortization  of 
capitalized  software construction  costs,  royalty  fees  paid  to 
third  parties   under licensing agreements and the cost of
distributing software products.

Cost  of  licenses revenue represents variable costs associated 
with the  generation  of  licenses revenue.    These  costs 
increased  to $27,719  in  1996  from  $24,659  and  $20,311  in 
1995  and   1994, respectively.    As  a  percent of software 
licenses  revenue  these represent 18%, 19% and 18% in 1996, 1995
and 1994, respectively.   In absolute  dollars,  the Company expects
these costs  to  increase  in direct proportion to licenses revenue
growth.

Cost of maintenance and services revenue increased to $60,454 in
1996 from  $40,342  and  $31,347  in 1995 and 1994,  respectively. 
 As  a percent  of software maintenance and services revenue these
represent 46%, 43% and 45% in 1996, 1995 and 1994, respectively.  
The increase in  1996 is primarily the result of hiring and start-up
costs for new employees  associated  with the growth  in  services 
revenue.    The decline  in  1995  was attributable to the sale  of 
our  low  margin European  services  business.   The Company expects 
these  costs  to increase  in absolute dollars in proportion to
software services  and maintenance growth.

Selling  and  Marketing  Expenses.  Selling  and  marketing 
expenses consist  of  the  costs  associated  with  the  worldwide 
sales  and marketing   staff,  advertising  and  product 
localization.    These expenses amounted to $109,700, $97,272 and
$99,744 in 1996, 1995  and 1994,  respectively.  These amounts
represent 38%,  43%  and  54%  of total  revenue for 1996, 1995 and
1994, respectively.   1996  selling costs  as a percentage of
revenue decreased due to lower selling  and marketing costs related
to software services and maintenance revenue. The  selling and
marketing expense decrease in 1995 from 1994 is  due to  a reduction
in staff and related staff costs partially offset  by an  increase 
in  sales incentives for both the direct  and  indirect channels.  
The  Company  expects to continue  to  expand  its  sales
organization to meet the growing customer demand for its products
and services.

Research  and Development Expenses.  The Company continues to 
invest significant  amounts in the technological advancement of its 
product line.  Research and development expenses amounted to
$30,719, $24,472 and  $24,917  in  1996, 1995 and 1994,
respectively.   These  amounts represent 11%, 11% and 13% of total
revenue for 1996, 1995 and  1994, respectively.   In  1995, 
research and  development  expenses  as  a percent  of total revenue
decreased because of a reduction  in  staff and  related staff costs
which occurred in the fourth quarter of 1994 and first quarter of
1995.  The Company expects that the research and development  costs 
will  increase in absolute  dollars  due  to  the acceleration of
the development of its I-DEAS  Master Series software and other
product initiatives.

Research and development expenses consist of expenses for
development of  software products which cannot be capitalized in
accordance  with Statement   of   Financial  Accounting  Standards 
(SFAS)   No.   86, "Accounting for the Costs of Computer Software to
be Sold, Leased, or Otherwise  Marketed."  Research  and 
development  expenses   exclude internally developed capitalized
software costs of $9,679, $6,928 and $9,312  in  1996,  1995  and
1994, respectively.   These  capitalized amounts  represent  24%, 
22%  and 27% of  research  and  development expenses  in  1996, 1995
and 1994, respectively.   The  reduction  in 1995  software
capitalization was the result of a staff reduction  in early  1995. 
  The  staff  levels were increased  in  1996  to  meet development
needs resulting in increased software capitalization.

General  and  Administrative  Expenses.  General  and 
administrative expenses  consist  of  costs associated with the
corporate,  finance, human resource and administrative staffs. 
General and administrative expenses  amounted to $16,139, $13,584
and $13,501 in 1996, 1995  and 1994,  respectively.  These amounts
represent  6%, 6% and 7% of total consolidated  revenue  for 1996,
1995 and  1994,  respectively.   The Company expects general and
administrative costs to remain stable  as a percent of revenue.



Equity in Losses of Affiliates

During  1992,  the Company and Control Data Systems,  Inc.  formed 
a joint  venture  known  as  Metaphase  Technology,  Inc. 
(Metaphase).  Metaphase  is  involved  in  developing and  marketing 
product  data management  software.   The Company pays royalty  fees 
to  Metaphase based upon the amount of PDM sales.

During  1994, the Company formed a joint venture with Siemens
Nixdorf Informationssysteme AG (SNI), SDRC Software and Services,
GmbH  (SDRC GmbH)  to  market the Company's software products in
Central  Europe.  The Company's equity in the losses of affiliates
represents its share of  Metaphase  and SDRC GmbH joint venture
losses,  the  majority  of which  resulted  from  the SDRC GmbH
joint venture.    In  1995,  the Company  purchased the remaining
shares in SDRC GmbH at its net  book value.   As of the acquisition
date, 100% of the operating results of SDRC GmbH were included in
the consolidated financial statements.

In  1996,  equity  in loss of affiliates primarily represents 
SDRC's share of the Metaphase joint venture losses.

Acquisition of Metaphase Technology, Inc.

In  January  1997,  the  Company  acquired  the  remaining  stock 
of Metaphase  Technology,  Inc. and certain  assets  from  Control 
Data Systems, Inc. for approximately $31,000.  The purchase price
includes cash and a stock warrant.  The Company expects a
significant one-time charge  to  earnings in 1997 for the write-off
of purchased  research and  development in process.   The
transaction will be accounted  for as a purchase.

Acquisition of Camax Manufacturing Technologies, Inc.

On  January 16, 1996, the Company entered into a definitive
agreement to  acquire  Camax Manufacturing Technologies, Inc.
(Camax)  and  its wholly    owned    subsidiaries.   Camax  
provides    computer-aided manufacturing   (CAM)   software  for 
computerized-numerical-control machining   operations,  with 
products  and  services  designed   to simplify,  automate and
optimize the machining process to  streamline production and
accelerate time-to-market.

During  1996,  SDRC  issued Common Stock having  a  market  value 
of $30,000 in exchange for 100 percent ownership of Camax common 
stock. The  acquisition  was  accounted for under  the 
pooling-of-interests method  and all prior periods presented have
been restated to reflect Camax  results.   In 1996, SDRC recorded
other expense of  $1,102  in costs related to the acquisition.

Litigation Settlement

In  December  1995, the Company and plaintiffs' counsel  in  a 
class action  lawsuit  entered into a Memorandum of  Understanding 
setting forth  the terms of a proposed settlement.  Pursuant to the 
proposed settlement,  the  Company agreed to establish a  settlement 
fund  of $27,600 consisting of $17,600 cash and $10,000 in the form
of  shares of   the  Company's  common  stock.   The  anticipated 
cost  of  the settlement  net  of estimated insurance proceeds was
recorded  as  an expense  in 1995.  The insurance proceeds of $5,000
were received  in 1996.  In January 1996, $17,600 was transferred to
a settlement  fund in accordance with the Memorandum of
Understanding.   During 1996,  a final  settlement between the
Company and the plaintiffs was accepted by the Court and the Company
expects to issue $10,000 in stock to the settlement fund during
1997.

Other Income, Net

Other  income,  net,  consists principally  of  interest  income 
and foreign  currency  losses.   For the three-year  period  ended
December  31,  1996, interest income increased due  to  interest 
for income  tax  refunds received in 1995, higher investment
balances  in 1995  and  1996 and increasing interest rates
throughout the  period.  1996 other income is offset by a $950
settlement of the shareholders' derivative  litigation.  In 1995,
other income, net, is offset  by  a net loss of $1,878 resulting
from the sale of the United Kingdom test and analysis division.

Income Taxes

The  Company  recorded tax expense of $8,636, $7,179  and  $3,881 
in 1996, 1995 and 1994, respectively.  In each of these years
(including 1995  and  1994  when  the  Company incurred losses), 
the  Company's provision  for  income  taxes consisted  primarily 
of  income  taxes currently  payable  to foreign jurisdictions and
foreign  withholding taxes  incurred  on the Company's software
licensing revenue.   These withholding  taxes can be credited
against the Company's U.S.  income tax liability.  The Company is
not currently in a position to utilize all of these foreign tax
credits (FTCs) on its U.S. return.  The FTCs and  other  tax 
carryforwards are available to  offset  future  U.S. income  tax
liabilities, subject to various restrictions.  No benefit was 
currently recognized for a substantial portion of the  Company's
U.S.  deferred tax assets since it is more likely than not that 
they will not be realized based upon the Company's current and
anticipated mix  of  domestic and foreign pre-tax accounting income,
tax  credits and  deductions  from non-qualified stock option 
exercises.   As  of December 31, 1996,   $15,353 of the valuation
allowance of $34,837 is attributable to the tax benefits of stock
option exercises  and  such benefits  will  be credited to capital
in excess of stated  value  if realized.

In 1994, the Company received a tax refund of $1,754 for research
and experimentation credits  not previously recorded.

Liquidity and Capital Resources

As  of  December  31, 1996, the Company had $100,289  in  cash, 
cash equivalents  and liquid investments.   The Company's working 
capital was  $66,519 and the Company had no borrowings.  The Company
also has an unsecured bank line of credit of $15,000.

During  1996,  1995 and 1994 the Company generated  cash  flows 
from operations  of  $30,094,  $33,793  and  $8,181,  respectively. 
  The increased  income in 1996 was offset by the $17,600  payout 
for  the class  action  litigation  settlement.   The  increase  in 
net  cash provided  by operations in 1995 was primarily due to the
increase  in operating  income and the increase in deferred revenue, 
net  of  the accounts receivable increase.

The  Company used $34,238, $8,701 and $21,858 during 1996,  1995 
and 1994,  respectively,  for  investing activities.   The 
reduction  in investing  activities  from 1994 to 1995 was 
primarily  due  to  the conversion of marketable securities into
cash.   In 1996, the Company added  capital  equipment  of $14,250.
This  consisted  primarily  of furniture  and workstations to
accommodate the increase  in  employee headcount.

Net  cash  provided by financing activities was $13,276, $12,623 
and $747 during 1996, 1995 and 1994, respectively, primarily
representing proceeds from the Company's stock option programs.

The  Company's  sources  of liquidity and  funds  anticipated  to 
be generated  from  operations  are expected  to  be  adequate  for 
the Company's   cash  requirements  in  the  foreseeable   future. 
  The acquisition of the remaining 50% share of Metaphase
Technology,  Inc. will   be  funded with cash generated from
operations.   The  Company paid no dividends during the period 1994
through 1996 and intends  to continue  its policy of retaining
earnings to finance future  growth. The  Company  has  no other
current commitments for material  capital expenditures.   See  Note
8 to the consolidated financial  statements for  additional
commitments and contingencies.  The Company does  not expect
inflation to have a material impact on its future operations.



Factors That May Affect Future Results

Forward  looking statements and the Company's results are subject 
to certain  risks  and uncertainties, including those  discussed 
below, that could cause actual results to differ from those
disclosed.   Any risk and uncertainty posed by competitive,
technological or financial factors could have an immediate and
significant adverse effect on the trading price of the Company's
stock in any given period.

Future  results  could be impacted by factors such as customer 
order delays, a slower growth rate in the market, increased
competition  or adverse  changes  in  general  economic  conditions 
in  any  of  the countries  in which the Company does business.  The
loss of  a  major customer or a reduction in orders from a major
customer could have  a significant  impact to the results of
operations  in  any  particular quarter.   Historically,  a 
significant  portion  of  the  Company's revenue  is generated from
shipments in the last month of a  quarter.  In addition, higher
volumes of orders have been experienced  in  the second  and  fourth 
quarter.  The  concentration  of  orders   makes projections  of
quarterly financial results difficult.  If  customers delay  their 
orders  or  a disruption in the Company's  distribution occurs,
quarterly results of operations in any particular quarter may be 
negatively  impacted.   A significant portion  of  the  Company's
revenue   is  from  the  international  market.   As  a  result, 
the Company's  financial  results could be impacted by  weakened 
general economic conditions, differing technological advances or
preferences, volatile foreign exchange rates and government trade
restrictions  in any  country in which the Company does business. 
The Company  relies on  distributors, representatives and value
added resellers to market its products.  The Company's revenue in
any particular quarter may be negatively  impacted by a lower than
anticipated performance  of  any significant distributor,
representative or value added reseller.

The  Company's  success is dependent on its ability  to  continue 
to develop,  enhance  and  market new products to  meet  its 
customers' sophisticated needs in a timely manner and which are
consistent  with current  technological  developments.   The 
Company's  success  also depends  in  part on its ability to attract
and retain technical  and other  key  employees  who  are  in  great 
demand,  to  protect  the intellectual  property rights of its
products  and  to  continue  key relationships with third party
authors.  As development cycles become shorter,  product  quality,
performance, reliability,  ease  of  use, functionality,  breadth
and integration may be impacted.   Therefore, customer   acceptance 
of  new  products  cannot  be  assured.    The CAD/CAE/CAM  software 
industry is highly  competitive.   The  entire industry may
experience pricing and margin pressure which as a result could 
adversely affect the Company's operating results and financial
position.

In  addition, the Company's expense levels are based, in part, on
its future  revenue expectations. The Company continues to  increase 
its operating expense levels to meet the growing customer demand for 
the Company's  products and services.  If revenue is below 
expectations,
operating  results could be adversely and materially  affected.  
Net income  may be disproportionately affected by an unexpected
reduction in  revenue  because  the  Company's  expense  levels  are 
generally committed  in advance and a relatively small portion of
the Company's expenses vary with revenue.

The  acquisition  and integration of the remaining  50%  interest 
in Metaphase  Technology,  Inc.  may  impact  future  results.   
Future results  could also be impacted by the continued integration 
of  the Company and Camax Manufacturing Technologies, Inc. (see Note
2 to the Consolidated Financial Statements).  In addition, the
Company  is  in the  process  of  upgrading  its  world-wide 
information  management system.   Such a major undertaking could
cause significant disruption as  a  result  of  unexpected delays in
the  implementation  of  this project.   There  can  be  no 
assurance that  the  project  will  be completed within the
projected time frame and budget.

The  trading  price of the Company's stock, like other  software 
and technology  stocks,  is  subject  to significant  volatility 
due  to factors  impacting  the overall market which  are  unrelated 
to  the Company's  performance.   The historical results  of 
operations  and financial  position of the Company are not
necessarily indicative  of future  financial performance.  If
revenues or earnings fail to  meet securities  analysts'
expectations, there could be an  immediate  and significant adverse
impact on the trading price of the Company stock.

The  Company  has not experienced a material adverse impact  of 
such risks  or  uncertainties  and  does not anticipate  such  an 
impact.  However,  no assurance can be given that such risks and
uncertainties will  not  affect the Company's future results of
operations  or  its financial position.
                                  
                                  
                                  
                  Report of Independent Accountants


To the Board of Directors
and Shareholders of
Structural Dynamics Research Corporation



In  our opinion, the accompanying consolidated balance sheet and 
the related consolidated statements of operations, of cash flows 
and  of shareholders'  equity present fairly, in all material 
respects,  the financial  position of Structural Dynamics Research 
Corporation  and its  subsidiaries at December 31, 1996 and 1995,
and the  results  of their operations and their cash flows for each
of the three years  in the  period  ended  December 31, 1996, in
conformity  with  generally accepted  accounting principles. These
financial statements  are  the responsibility of the Company's
management; our responsibility is  to express an opinion on these
financial statements based on our audits.  We  conducted  our 
audits  of these statements  in  accordance  with generally accepted
auditing standards which require that we plan  and perform  the 
audit to obtain reasonable assurance about whether  the financial 
statements  are free of material misstatement.   An  audit includes
examining, on a test basis, evidence supporting the  amounts and
disclosures in the financial statements, assessing the accounting
principles  used  and significant estimates made by  management, 
and evaluating the overall financial statement presentation.  We 
believe that  our audits provide a reasonable basis for the opinion
expressed above.

As  described in Note 7 to the consolidated financial statements, 
in 1994  the Company changed its method of accounting for
postemployment benefits.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Structural Dynamics Research Corporation


(in thousands, except per share data)

(1)  Summary of Significant Accounting Policies

Business

Structural Dynamics Research Corporation (the "Company" or "SDRC")
is a  leading  international  supplier of mechanical  design 
automation (MDA)  software, product data management (PDM) software 
and  related services.

Basis of Consolidation

The  consolidated financial statements include the  accounts  of 
the Company and its wholly owned subsidiaries.  Investments in which 
the Company has significant influence, but not control, are
accounted for under  the equity method.  All significant
intercompany balances  and transactions have been eliminated.

Use of Estimates

The  financial  statements,  which are prepared  in  conformity 
with generally accepted accounting principles, require management to 
make estimates  and  assumptions that affect the reported amounts 
in  the consolidated  financial  statements and accompanying  notes. 
 Actual results  could  differ  from those estimates.  Significant 
estimates based  on  the facts and circumstances existing at the 
date  of  the financial  statements include the estimated useful
lives of  computer software construction costs and the likelihood of
realization of  the deferred tax assets.

Revenue Recognition

The use of software programs is licensed through the Company's
direct sales  force  and by specific arrangements with certain
distributors, value-added  resellers and other marketing
representatives.   Revenue generated  from  licenses is recognized
when the  following  criteria have  been met: (a) a written order
for the unconditional license  of software  and  a software license
agreement have been received,   (b) the  Company  has shipped the
products to the customer and  performed substantially  all  services
for which  it  was  committed,  (c)  the customer is obligated to
pay and (d) collectibility is probable.

Under the terms of a former licensing agreement with an OEM
customer, the  Company  was  unable to determine the amount of 
revenue  earned until cash was received from the customer.  In 1994,
when the Company terminated  this  licensing agreement, revenue 
totaling  $5,877  was recorded on the cash basis.

Revenue  from  maintenance contracts is recognized ratably  over 
the term  of  the  agreement  and  the deferred  portion  represents 
the substantial  component of deferred revenue.  Revenue from
engineering consulting, customer training and other services is
recognized as the service is performed.

Cost of Revenue

The  cost  of licenses primarily consists of the cost of
distributing the  software  products  and an allocation  of  the 
amortization  of capitalized  software  construction costs and
royalty  fees  paid  to third  parties under licensing agreements. 
 Cost of maintenance  and services primarily consists of the staff
and related costs associated with  the generation and support of
software service revenue  and  an allocation  of the amortization of
capitalized software  construction costs  and  royalty  fees  paid 
to  third  parties  under  licensing agreements.   The allocation
between cost of licenses and maintenance and  services  is  based
upon the percentage of the  related  revenue source  to  total
revenue.   Management believes that the methodology for allocating
the costs is reasonable.



(1)  Summary of Significant Accounting Policies - continued

Cash Equivalents and Marketable Securities

Cash  equivalents  include  highly  liquid  investments  in 
interest bearing  accounts, commercial paper and reverse repurchase
agreements with  an  original  maturity  of  less  than  90  days. 
  Marketable securities  consist  of  U.S. treasuries and U.S. 
government  agency obligations.   Short-term marketable securities
have a maturity  term in  excess  of 90 days but less than one year. 
Long-term  marketable securities have a maturity term in excess of
one year.   The  Company also has an unused unsecured $15,000 bank
line of credit.

All  cash  equivalents and marketable securities  are  classified 
as available  for sale and recorded at market value.   Unrealized 
gains and  losses  are  included in a separate component  of 
shareholders' equity.    Realized  and unrealized gains and losses 
are  determined based on the specific identification method.

Financial Instruments

The  carrying  amounts  of  cash  and  cash  equivalents, 
marketable securities,  accounts receivable, accounts payable,
accrued  expenses and forward foreign exchange contracts approximate
fair value due  to the short-term nature of these financial
instruments.

Concentrations of Credit Risk

Cash  equivalents,  marketable  securities  and  accounts 
receivable represent  a  potential  credit risk to  the  Company.  
The  Company invests   its  excess  cash  with  government  and 
major   financial institutions  having  strong credit ratings.   
Company  policy  sets credit  ratings  and  maturity terms that
limit the  risk  of  credit exposure and maintain necessary
liquidity.

The  Company's revenue is generated from a significant customer 
base in   diversified   industries  across  different  geographic  
areas. Revenue  from a customer represented 11% of consolidated 
revenue  in 1996  and  a distributor represented 12%, 13% and 10% of
consolidated revenue  in 1996, 1995 and 1994, respectively.  The
Company  performs ongoing  credit evaluations of its customers and
has not  experienced any  material losses related to an individual
customer or  groups  of customers  in  any particular geographic
area.   Management  believes allowances   for  potential  credit 
losses  are  adequate   in   the circumstances.

Foreign Currency Translation

For  1996 the functional currency of the international operations 
is the  local  currency.   Foreign  currency  financial  statements 
are translated  at  period-end exchange rates for assets and 
liabilities and at weighted average exchange rates for the results
of operations. The  translation  gains  and losses, which  were  not 
material,  are accumulated  in a separate component of shareholders' 
equity.    The functional  currency changed to the operations' local 
currency  from the U.S. dollar in 1996 based upon changes in the
Company's operating and  economic  environment.   The Company's
European operations  have become   more  autonomous  due  to 
improved  profitability  of   the subsidiaries and have generated
sufficient cash flows from operations to  support their operating
and capital needs.  Utilization of  local European  resources  have
been expanded due  to  the  local  European customer demand of
implementation, support and customization  of  the Company's 
software  products  and the establishment  of  a  European product
development staff.   Prior to 1996, for operations where  the
functional  currency was the U.S. dollar, the foreign currency 
gains and losses, which were not material, were included in
determining the results of operations.

Foreign Exchange Contracts

The   Company   enters   into  forward  foreign  exchange  contracts
denominated  in foreign currencies to hedge certain foreign 
currency denominated  receivables.   Any market gains  and  losses 
associated with these financial instruments are recorded currently
in income  to offset  any  gains and losses arising from foreign
currency  exchange transactions.  The resulting gains and losses
were not material.  The interest  element of the foreign currency
instruments  is  recognized over  the  life  of  the contract.  As
of   December  31,  1996,  the Company   did  not  have  any 
forward  foreign  exchange   contracts outstanding.


(1)  Summary of Significant Accounting Policies - continued


Property and Equipment

Depreciation  for property and equipment is primarily computed 
using the straight-line method over the estimated useful life of the
asset. Leasehold  improvements are amortized using the straight-line 
method over the lesser of the life of the lease or the estimated
useful life of  the improvement.  The general ranges of years used
in calculating depreciation and amortization are: computer and other
equipment,  2-5 years;   office   furniture  and  equipment,   7  
years;   leasehold improvements, 1-10 years.

Computer Software Construction Costs

The Company designs, develops and markets computer software
products. Costs related to the construction of software that are
incurred after the  technological  feasibility of the product has
been  demonstrated are capitalized and amortized over the useful
lives of such software.  Computer  software  construction costs are
shown net  of  accumulated amortization  of $32,022 and $20,243 at
December 31, 1996  and  1995, respectively.   Beginning in 1996, the
Company began  amortizing  the software  construction costs related
to new releases  of  the  I-DEAS Master  Series  product  over a
three year   period  based  upon  the estimated  future  economic
life of the  product.    Amortization  is calculated on a  
product-by-product basis and is the greater of  the ratio that
current product revenue bears to the total of current  and
anticipated  future years' revenue or the straight-line  method 
over the remaining estimated economic lives of the software
products.

Income Taxes

In accordance with Statement of Financial Accounting Standards
(SFAS) No.  109,  "Accounting  for Income Taxes," deferred  tax 
assets  and liabilities   are   recognized  for  the  future   tax 
 consequences attributable to differences between the financial
statement  carrying amounts of assets and liabilities and their
respective tax bases.  As of  December  31,  1996, no benefit was
currently  recognized  for  a substantial  portion of the Company's
U.S. deferred tax assets  since it  is more likely than not that
they will not be realized based upon the Company's current and
anticipated mix over the next four years of domestic  and  foreign
pre-tax accounting income,  tax  credits,  and deductions from
non-qualified stock option exercises.

The  Company  does  not accrue Federal income taxes on 
undistributed earnings  of  its  foreign subsidiaries that (1) have 
been,  or  are intended to be, permanently reinvested or (2) if
remitted, would  not have   material  income  tax  consequences. 
Undistributed   earnings amounted to approximately $12,396 at
December 31, 1996.

Per Share Data

Income  (loss)  per  common and common equivalent share  is 
computed using  the  weighted  average number of common  and 
dilutive  common equivalent  shares outstanding during the period.
Primary  and  fully diluted  income  (loss)  per share and common
and  common  equivalent shares  are  the  same  for all periods
presented.   Dilutive  common equivalent  shares  are  calculated
using  the  treasury  method  and consist  of stock option grants
and an estimated number of shares  to be issued in settlement of
litigation (see Note 8).


(2)  Business Acquisitions

Metaphase Technology, Inc.

In  1992  the  Company and Control Data Systems, Inc.  established 
a joint  venture  company, Metaphase Technology, Inc.  (Metaphase), 
to develop  and market product data management software worldwide. 
 The Company initially owned a 30% interest and increased such
interest to 50%  during  1993.   The Company's investment in
Metaphase  has  been accounted for on the equity basis.

In January 1997 the Company acquired the remaining stock of
Metaphase and  certain  assets  of  Control Data  Systems,  Inc.'s 
global  PDM software   sales  and  support  business.   The 
purchase  price   of approximately $31,000 includes cash and a stock
warrant.  The warrant is  exercisable for 750 shares of the
Company's common stock  without par  value  at  the exercise price
of $28 per share  and  expires  on December 31, 1998.   The
acquisition will be accounted for using  the purchase method.

Camax Manufacturing Technologies, Inc.

In   June  1996  the  Company  completed  the  acquisition  of 
Camax Manufacturing  Technologies,  Inc.  (Camax)  and  its  wholly 
 owned subsidiaries.  Camax  provides  computer-aided  manufacturing 
 (CAM) software  for  computerized-numerical-control  machining 
operations. The  Camax  products and services are designed to
simplify,  automate and  optimize  the  machining process to 
streamline  production  and accelerate time-to-market.

In  exchange  for 100 percent ownership of Camax common  stock, 
SDRC issued  approximately  967  shares of  SDRC  common  stock  and 
paid approximately   $1,236   to  a  Camax  shareholder   who   
exercised dissenter's  rights.   The market value of the shares and 
cash  paid was   approximately  $30,000.  Acquisition  charges  of 
$1,102  were recorded  in  the second quarter of 1996.  The
acquisition  has  been accounted  for  as a pooling-of-interests. 
All historical  financial data of the Company has been restated to
include the results of Camax for all periods presented.

Of  the $12,482 in tax carryforwards available at December 31, 
1996, $6,908 expire in the years 1997 through 2000 and the remainder
expire thereafter  through  the  year 2011.  $2,125 of  alternative 
minimum taxes never expire.

The net change in the valuation allowance for deferred tax assets
was a decrease of $1,676 in 1996 and an increase of $12,679 in 1995. 
 Of the  $34,837 in valuation allowance at December 31, 1996,
$15,353  is attributable  to  the  tax benefit of stock option 
exercises.   Such benefits  will be credited to capital in excess of
stated value  when realized.



(6)  Shareholders' Rights Plan

In 1988 the Board of Directors adopted a Shareholders' Rights Plan
to protect  shareholders'  interests in  the  event  of  an 
unsolicited attempt  to  gain  control of the Company.  Under  the 
Shareholders' Rights Plan, shareholders are granted certain rights
in the event  of a  triggering event ("Rights").  The Rights become
exercisable  if  a person acquires 20% or more of the Company's
outstanding common stock or  announces a tender offer which would
result in a person or  group acquiring  20% or more of the common
stock (Distribution Date).   If, at  any  time  following the
Distribution Date, the Company  has  not redeemed the Rights, the
Company becomes the surviving corporation in a  merger or a person
becomes the beneficial owner of 20% or more  of the  Company's
common stock (Triggering Date), each holder of a Right will  have
the right to purchase shares of the Company's common stock having a
value equal to two times the Right's exercise price of $110. If,  at 
any  time  following the Triggering  Date,  the  Company  is
acquired  in  a  merger or other business combination transaction 
in which the Company is not the surviving corporation, each holder
of  a Right shall have the right to purchase shares of common stock
of  the acquiring  company  having a value equal to two  times  the 
exercise price of the Right.  The Rights expire on August 10, 1998,
and may be redeemed by the Company for $.0025 per Right.



(7)  Common Stock and Employee Benefit Plans

Stock Option Plans

Under  the 1991 Employee Stock Option Plan, the Company has 
reserved 5,300  shares of previously unissued common stock.   Under
the  plan, options  to  purchase  shares may be granted  to  key 
employees  and executive officers at the fair market value at the
date of grant. 

In 1991 the adoption of the Director's Non-Discretionary Stock
Option Plan converted the Amended and Restated 1986 Stock Option
Plan into a non-discretionary plan allowing future grants to outside
directors at the  fair market value at the date of grant.  Under the
original 1986 plan,  the  Company had reserved 7,000 shares of
previously  unissued common  stock.  The  status  of  all
outstanding  options  previously granted to employees remained
unchanged.

In  1994  the shareholders adopted the 1994 Long-Term Stock
Incentive Plan,  allowing  stock  incentives  including  stock 
options,  stock appreciation rights, stock awards, and any
combination to be  granted to  employees.   The  number of shares
with respect  to  which  stock incentives may be granted in one
calendar year shall not exceed 4% of the   Company's  issued  and 
outstanding  common  stock.   No  stock incentives  other than
non-qualified stock options have been  granted under the 1994 plan.

Under  the plans, employee options expire ten years from the date 
of grant and are exercisable as follows: 33% on the first
anniversary of the  grant date; an additional 34% on the second
anniversary; and all or  any  remaining options on the third
anniversary until expiration.  Director  options expire five years
from the date of  grant  and  are exercisable 50% upon expiration of
six months from the grant date and all  or  any remaining options on
the first anniversary of the  grant date until expiration.

With  the acquisition of Camax on June 30, 1996, the Company 
assumed approximately  175  outstanding stock  options  representing 
all  of Camax's  obligations  under  five existing  stock  option 
plans  and certain  out-of-plan options.  The assumed stock  options 
and  stock appreciation rights were generally granted to employees
and directors of  Camax at 100% of the market value at the date of
grant and expire ten  years from date of grant.   No additional
stock options will  be granted under the Camax plans.

Stock Purchase Plan

Under  the Stock Purchase Plan, all domestic full-time employees 
who are  non-executive  officers are entitled to purchase  the 
Company's common  stock  at  90% of fair market value.  Employees 
electing  to participate must contribute at least 1% with a maximum
of 10% of  the participant's base salary and commissions each month. 
All incidental expenses  related to the issuance of these shares
including  the  10% discount  have  been  charged  to income.   The 
plan  has  no  fixed expiration date, may be terminated by the
Company at any time and has no limitation on the number of shares
that may be issued.


(7)  Common Stock and Employee Benefit Plans - continued

Tax Deferred Capital Accumulation Plan

The  Structural  Dynamics Research Corporation Tax  Deferred 
Capital Accumulation  Plan  (401(k)  Plan) is  a  defined 
contribution  plan covering  all  salaried employees of the domestic 
divisions  of  the Company.    Employees may make contributions to
the  401(k)  Plan  by authorizing a reduction of their compensation
of at least 1% up to  a maximum of 15%.   The Company may provide a
matching contribution  in the  form  of  Company  stock or cash
equal to 50%  of  the  employee contribution,  up  to  a maximum of
6% of the employee  compensation.  Participants  are immediately
vested in their voluntary contributions and  are  vested  in the
Company contributions after three  years  of continuous service.

Other Employee Benefit Plans

The   Company  provides  retirement  benefits  to  substantially 
all employees   through  defined  contribution  plans.    The  
Company's contributions are primarily based on employee compensation
and  years of  service.   Expenses related to the 401(k) Plan and
other  defined contribution plans were approximately $3,225, $3,044
and  $2,122   in 1996, 1995 and 1994, respectively.

Postemployment Benefits Plans

The  Company provides severance benefits for involuntarily
terminated employees  attributable to employees' prior service.   In 
the  first quarter  of  1994,  the cumulative effect of adopting 
SFAS  No.  112 "Employers' Accounting for Postemployment Benefits"
reduced income by $3,896, net of zero tax benefit.

Stock-Based Compensation

The  Company has adopted the disclosure-only provisions of  SFAS 
No. 123,  "Accounting  for Stock-Based Compensation."   
Accordingly,  no compensation  cost has been recognized in the
results  of  operations for  the  stock  option  grants.    Had 
compensation  cost  for  the Company's stock option plans been
determined based on the fair  value at  the  grant date for awards
in 1996 and 1995 consistent  with  the provisions  of  SFAS  No.
123, the Company's net  income  (loss)  and income  (loss)  per
share would have been reduced to  the  pro  forma amounts as
follows:


                                                 1996      1995

Net income (loss) - as reported                $33,689   $(7,471)
Net income (loss) - pro forma                   28,268    (8,547)
Income (loss) per share - as reported              .97      (.24)
Income (loss) per share - pro forma            $   .81   $  (.28)

The  pro  forma effect on the Company's net income (loss) and 
income (loss)  per share for 1996 and 1995 is not representative of
the  pro forma  effect  in future years.  The pro forma effect does 
not  take into  consideration compensation expense related to grants
made prior to 1995 or additional grants in future years which are
anticipated.  The fair value of each option is estimated on the date
of grant using the  Black-Scholes option-pricing model with the
following  weighted-average assumptions used for grants in 1996 and
1995: dividend  yield of 0%; expected volatility of 62.8%; risk-free
interest rate of 5.6%; and  expected  terms  of 1.86  years, 
adjusted  for  vesting requirements.



(8) Commitments and Contingencies

Except  for  the  following matters, SDRC  is  not  a  party  to 
any litigation other than ordinary routine litigation incidental  to 
its business.   The  Company  was a defendant  in  a  class  action 
suit alleging violations of certain federal securities laws,
captioned  In Re:  Structural Dynamics Research Corporation
Securities  Litigation, United States District Court, Southern
District of Ohio, Consolidated Master  File No. C-1-94-630.   In
December 1995, the parties to  this matter  entered  into a
Memorandum of Understanding  for  settlement, subject  to  final 
Court approval.  On March  22,  1996,  the  Court approved  the 
proposed  settlement and a final  order  was  entered.  Pursuant  to 
the  order,  a settlement fund  of  $37.5  million  was established, 
consisting  of  $17.6  million  cash  provided  by  the Company,
$10.0 million in shares of the Company's common stock (to be
valued-based  on  the market price at the time of distribution), 
and $9.9 million cash provided by the Company's former accountants. 
 The settlement does not constitute an admission of liability on the 
part of  any defendant.   The Company's Board of Directors
determined that the  settlement  was  in the best interest of  the 
Company  and  its shareholders  in  light of the uncertainty of the
outcome,  the  high cost  of continued litigation, and the high
level of management  time and attention continued litigation would
have required which could be better spent on the Company's business.

The  Company  was  a  party  to shareholders'  derivative 
litigation captioned  In Re: Structural Dynamics Research
Corporation Derivative Litigation, United States District Court,
Southern District of  Ohio, Consolidated  Master  File  No.
C-1-94-650.   The  Company  paid  the plaintiffs' counsel fees of
approximately $900 and $50 for their out-of-pocket  expenses in full
settlement of the matter.   The  parties' agreement  was approved by
the United States District Court  on  July 19, 1996.

Based on the same facts which gave rise to the Class Action Case 
and the Derivative Case, the Securities and Exchange Commission
commenced a  formal,  private  investigation of SDRC in  September 
1994  which remains  pending.  SDRC is fully cooperating with this 
investigation but cannot predict its outcome.

Pursuant  to certain contractual obligations, the Company has 
agreed to  indemnify  its directors and officers under certain
circumstances against  claims arising from lawsuits.  The Company
may be  obligated to indemnify certain of its directors and officers
for the costs they may incur as a result of the lawsuits.

In July 1995, SDRC sold its test and analysis division located in
the United  Kingdom  to  MascoTech Engineering  Europe  Limited  for 
net proceeds of $524 and realized a loss on the sale of $1,878.  The
loss includes foreign currency losses and estimated costs pertaining
to  a lease commitment.

Other consists of net foreign currency exchange gains and losses
and, in 1996, the derivative litigation settlement.
