ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

         (a) On November 14, 2000, PlanetCAD Inc., a Delaware corporation
("PlanetCAD" or the "Company"), completed the sale of its component software
division to Spatial Corp. ("Spatial Corp."), a wholly owned subsidiary of
Dassault Systemes Corp., a Delaware corporation ("Dassault"). The sale was
effected pursuant to a Purchase Agreement dated July 4, 2000, and amended on
September 2, 2000, by and among PlanetCAD, Spatial Components, LLC, a Delaware
limited liability company ("Spatial LLC"), and Dassault (the "Purchase
Agreement"), pursuant to which PlanetCAD formed Spatial LLC as a wholly owned
subsidiary and capitalized Spatial LLC with all of the assets and certain of the
liabilities of the component software division. Upon the closing of the sale
under the Purchase Agreement, PlanetCAD transferred to Spatial Corp., the
assignee of Dassault under the Purchase Agreement, 100% of the membership
interests in Spatial LLC, upon which Spatial LLC became a wholly owned
subsidiary of Spatial Corp. PlanetCAD and Dassault Systemes S.A., the parent
company of Dassault, have also entered into certain intellectual property
agreements, identified below, which agreements include various license, services
and co-branding agreements.

         As an inducement to PlanetCAD to enter into the Agreement, Dassault
agreed to make a $2.0 million investment in PlanetCAD in exchange for 555,556
shares of PlanetCAD's common stock pursuant to a Share Purchase Agreement, dated
as of November 14, 2000 (the "Share Purchase Agreement"), a conformed copy of
which is filed as an exhibit hereto. The shares of PlanetCAD's common stock
issued to Dassault under the Share Purchase Agreement carry the same rights as
the outstanding shares of PlanetCAD's common stock held by its existing
stockholders. As a result of the sale, Dassault and Dassault Systemes own, in
the aggregate (including exercise in full of all outstanding warrants to acquire
shares of common stock of PlanetCAD owned by Dassault Systemes), 1,004,831
shares of PlanetCAD's common stock. The Share Purchase Agreement provides
Dassault with registration rights, including "piggy-back" registration rights,
which would be triggered if, during the period of time that Dassault holds
shares of PlanetCAD's common stock subject to the registration rights, PlanetCAD
files a registration statement with the Securities and Exchange Commission (the
"Commission") offering its shares for its own account or for the account of
stockholders.

         In September 2000, Dassault made a loan to PlanetCAD for $2 million of
the purchase price for the sale of the component software business in advance of
the closing of the transaction. In November 2000, Dassault loaned an additional
$2 million of the purchase price to PlanetCAD. PlanetCAD repaid these loans,
including accrued and unpaid interest, as an offset against the purchase price
at the closing.

         In connection with the sale of PlanetCAD's software component division,
PlanetCAD and Dassault Systemes have entered into the following intellectual
property and/or software license agreements, each of which is filed as an
exhibit hereto:

         o Cross License Agreement;
         o Co-Branding Agreement;
         o Server Software License Agreement;
         o Web Services Agreement;
         o Joint Software License Agreement;
         o Master Software Reseller Agreement;
         o IntraVISION License Agreement; and
         o Catia V5 Galaxy Program Solution Provider Agreement.

         PlanetCAD filed a Confidential Treatment Request with the Commission
with respect to certain confidential portions of each of these agreements on
November 21, 2000 and filed an Amended Confidential Treatment Request on
February 21, 2001. The exhibits attached reflect revisions to the redacted
portions of such agreements based on comments received by PlanetCAD from the
staff of the Commission.

         (b) Not applicable.
