                Report of Independent Accountants

To the Participants and Administrator
of the Structural Dynamics Research Corporation
Tax Deferred Capital Accumulation Plan


In our opinion, the accompanying statements of net assets
available for benefits and the related statements of changes in
net assets available for benefits present fairly, in all
material respects, the net assets available for benefits of the
Structural Dynamics Research Corporation Tax Deferred Capital
Accumulation Plan (the "Plan") at December 31, 1998 and 1997,
and the changes in net assets available for benefits for the
year ended December 31, 1998 in conformity with generally
accepted accounting principles.  These financial statements are
the responsibility of the Plan'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.

Our audits were conducted for the purpose of forming an opinion
on the basic financial statements taken as a whole. The
supplemental schedules of Schedule of Assets Held for
Investment Purposes and Schedule of Reportable Transactions are
presented for the purpose of additional analysis and are not a
required part of the basic financial statements but are
supplementary information required by the Department of Labor's
Rules and Regulations for Reporting and Disclosure under the
Employee Retirement Income Security Act of 1974.  The fund
information in the statements of net assets available for
benefits and the statement of changes in net assets available
for benefits is presented for purposes of additional analysis
rather than to present the net assets available for plan
benefits and changes in net assets available for benefits of
each fund.  These supplemental schedules and fund information
are the responsibility of the Plan's management.  The
supplemental schedules and fund information have been subjected
to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in
all material respects in relation to the basic financial
statements taken as a whole.

Structural Dynamics Research Corporation
Tax Deferred Capital Accumulation Plan
Notes to Financial Statements
(Amounts in Thousands)

(1)  Description of Plan

The following description of the Structural Dynamics Research
Corporation Tax Deferred Capital Accumulation Plan (the "Plan")
provides only general information.  Participants should refer to
the Plan agreement for a more complete description of the Plan's
provisions.

  a)   General

The Plan is a defined contribution plan covering all salaried
employees of the domestic divisions of Structural Dynamics
Research Corporation (the Company).   It is subject to the
provisions of the Employee Retirement Income Security Act of
1974 (ERISA).

  b)   Contributions

A participant may make contributions to the Plan by authorizing
a reduction of their compensation (before-tax contribution) of
at least 1% up to a maximum of 15%.  The Company will reduce the
participant's compensation by the authorized percentage, subject
to limits specified by the Plan.  A participant may also make
voluntary contributions to the plan of rollover amounts from
other benefit plans.  The Company may provide a matching
contribution equal to 50% of the participant's contribution
(excluding rollovers) up to 6% of the participant's compensation.
Quarterly, the Board of Directors vote on the Company's matching
contribution amount, if any.  The Company's matching
contribution, if any, may take the form of either Company Common
Stock or cash in which participants, other than officers, can
redirect the Company's accumulated matching contribution into
other investment options offered under the Plan.

The Company may elect to make additional discretionary
contributions.  Such contributions shall be allocated to the
account of each participant in an amount equal to the ratio of
the employee's annual salary to the total annual salaries paid to
all participants.   Participants other than officers, can
redirect the Company's discretionary contributions into other
investment options offered under the Plan.  In 1998 and 1997, no
discretionary contributions were made.

c)   Participant Accounts

Each participant's account is credited with the participant's
contribution and allocation of the Plan earnings and Company's
contribution, if any.  Earnings of each investment fund are
allocated among the accounts of all participants in each fund in
the ratio each participant's account bears to the total account
balance.  The benefit to which a participant is entitled is the
benefit that can be provided from the participant's vested
account.

d)   Vesting

Participants are immediately vested in their voluntary
contributions plus actual earnings thereon.  One hundred percent
vesting in the Company contributions occurs after three years of
continuous service.  Forfeitures of Company contributions by
participants when they terminate before becoming vested are used
to reduce future Company contributions.  At December 31, 1998 and
1997, forfeited nonvested accounts totaled $145 and $36,
respectively.  During 1998 and 1997, employer contributions were
not reduced from forfeited nonvested accounts.

e)   Investment Options

The participants direct employee and employer contributions in
any of the following funds:

- -  Company Stock Fund
   Invests in the Company's Common Stock.
- -  Equity Income Fund
   Portfolio of the common stocks of major corporations and
   cash reserves.
- -  Balanced Fund
   Portfolio of U.S. Government securities, the common
   stocks of major corporations and cash reserves.
- -  Stable Value Fund
   Portfolio of investment contracts issued by insurance
   companies and banks.
- -  International Stock Fund
   Portfolio of common stocks of major foreign companies.
- -  New Horizons Fund
   Portfolio of common stocks of growing companies.
- -  Small Cap Value Fund
   Portfolio of common stocks of undervalued small
   companies.
- -  Science and Technology Fund
   Portfolio of common stocks of companies in the computer,
   electronics, biotechnology and chemical industries.
- -  International Bond Fund
   Portfolio of government and corporate bonds issued
   overseas.
- -  Spectrum Income Fund
   Portfolio of mutual funds including domestic and
   international bond funds, money funds and income-oriented
   stock funds.
- -  Spectrum Growth Fund
   Portfolio of mutual funds including domestic and
   international stock funds.

  f)   Payment of Benefits

Participants' accounts are distributable upon termination of
employment.   Participants may also make withdrawals in the case
of financial hardship (as determined by the Plan Administrator).

Amounts allocated to accounts of persons who have withdrawn from
participation in the earnings and operations of the Plan were
approximately $0 and $97 at December 31, 1998 and 1997,
respectively, and have been included as a component of assets
available for plan benefits.  The Plan is required to file a Form
5500 with the Internal Revenue Service which reflects benefits
payable as a liability and, accordingly, a deduction from assets
available for plan benefits.

g)   Loans

The Plan allows participants to borrow a minimum of $1 up to a
maximum equal to the lesser of $50 or 50% of their interest in
all funds other than the Company Stock Fund, within certain
limitations and upon approval by the Plan Administrator.   Loan
transactions are treated as a transfer to (from) the investment
options of the Plan from (to) the Loan Fund.   Loan terms range
from one to five years or up to 15 years for the purchase of a
primary residence.  The loans are secured by the balance in the
participant's account and bear interest at 2% above the prime
rate on the first day of the month preceding the effective date
of the loan.  The interest rate is fixed for the entire repayment
period.  Principal and interest is paid ratably through monthly
payroll deductions.

h)   Trust Agreement

The trustee of the plan is T. Rowe Price Trust Company (T. Rowe).
T. Rowe invests and holds all contributions made by the Plan
Administrator and allocates the amounts among the funds as
directed by the individual participants.


(2)  Summary of Significant Accounting Policies

  a)   Basis of Presentation

 The accompanying financial statements of the Plan have been
 prepared on the accrual basis of accounting.

  b)   Use of Estimates

 The preparation of financial statements in conformity with
 generally accepted accounting principles requires management to
 make estimates and assumptions that affect the reported amounts
 of assets and liabilities and disclosure of contingent assets and
 liabilities at the date of the financial statements and the
 reported amounts of revenues and expenses during the reporting
 period.  Actual results could differ from those estimates.

  c)   Investments and Income Recognition

  Money market accounts are valued at cost which approximates fair
  value.  All other investments are recorded at fair value based on
  quotations obtained from national securities exchanges as of the
  end of the year.  Participant loans are recorded at the unpaid
  principal balances of the individual loans.

  Purchases and sales of investments are recorded on the trade
  date.   Gains and losses on the sale of investments are
  calculated on the specific identification method.  Interest
  income is recorded on the accrual basis.   Dividends are recorded
  on the ex-dividend date.

  d)   Contributions

  Employee contributions are recorded in the period in which the
  Company makes payroll deductions from the Plan participants'
  earnings.

  e)   Expenses

  Certain administrative fees of the Plan are paid by the Company.
  Investment expenses are paid by the Plan and are deducted from
  investment income.

  f)   Payment of Benefits

  Benefits are recorded when paid.

  g)   Reclassifications

  Certain amounts in the 1997 financial statements have been
  reclassified to conform with the 1998 presentation.


(3)  Benefit Obligations

  Benefit obligations for persons who have withdrawn from
  participation in the Plan are as follows:

                                      =======      =======
(5)  Plan Termination

  Although it has not expressed any intent to do so, the Company
  has the right under the Plan to discontinue its contributions at
  any time and to terminate the Plan subject to the provisions of
  ERISA.   In the event of Plan termination, participants will
  become 100% vested in their accounts and the funds will be
  distributed or held until the time the member would otherwise
  have received their interest in the Plan.


(6)  Tax Status

  The Plan obtained its latest determination letter on June 3,
  1996, in which the Internal Revenue Service advised the Company
  that the Plan, including the amendments adopted on December 31,
  1993 and October 1, 1995, was in compliance with the applicable
  requirements of the Internal Revenue Code and its underlying
  trust is tax exempt as of the financial statement date.
