PLANETCAD INC. PRESS RELEASE

PLANETCAD INC. ANNOUNCES REJECTION OF UNSOLICITED OFFER FROM PCD INVESTMENTS,
LLC

BOULDER, Colo. Dec. 5, 2001--PlanetCAD, Inc. (AMEX: PCD) announced today that it
has received and, after review, rejected an unsolicited offer from PCD
Investments LLC.

Subject to certain terms and conditions, PCD Investments LLC sought the
support of the Board of Directors to purchase the outstanding shares of stock
of PlanetCAD at a price of $0.24 per share. PCD Investments, LLC is owned by
Eric Weissmann and Gary M. Jacobs, both residents of Colorado. The Board
viewed the proposal as inadequate and not reflective of PlanetCAD's true
value and not in the best interests of PlanetCAD's stockholders.

"Our Board is fully committed to acting in the best interests of PlanetCAD's
stockholders," said Jim Bracking, PlanetCAD's president and chief executive
officer. "Over the last several months, the Board of Directors has conducted
an in-depth review of PlanetCAD's strategic options. In light of that review
and the Board's analysis of PCD Investments' offer, the Board has concluded
that is in the best interests of PlanetCAD's stockholders to pursue
PlanetCAD's preexisting business strategy. Although book value does not
necessarily reflect market value, the Board noted that the offer by PCD
Investments is substantially below PlanetCAD's book value as of September 30,
2001, of approximately $7.3 million. The Board of Directors concluded that
PlanetCAD is not for sale and determined not to pursue the expression of
interest."
