Woburn, MA, May 28, 2003 - SensAble Technologies, Inc. announced today that it will hold a Special Interest Group (SIG) titled "Interoperability with Pro/ENGINEER® " during the PTC/USER Conference, June 8-11, 2003, at the Rosen Centre Hotel in Orlando, Florida. The SIG will be held on Wednesday, June 11th from 10 a.m. to 11:30 a.m. The workshop is open to all conference attendees and will include an interactive discussion about the interoperability of SensAble's FreeForm® modeling system with PTC's (Nasdaq:PMTC) Pro/ENGINEER in the product development process.

SensAble's FreeForm system allows users to create detailed, 3D digital models of organic, highly complex shapes with unprecedented speed and ease of use. Through the combination of intuitive 3D modeling and SensAble's patented PHANTOM™ force-feedback interface, the FreeForm system delivers an exceptional level of detail and interactivity.

SensAble's FreeForm system and PTC's family of solutions complement each other. Fisher-Price, one of SensAble's customers, has already benefited from this combination. Bud Kolich, Director R&D Technical Services at Fisher-Price said, "We used a combination of Pro/E and the FreeForm system on a recent project that resulted in great success-the design and development of a highly detailed dollhouse. Using this development process we reduced the overall schedule by eight weeks."

" A number of our FreeForm customers have successfully adopted a hybrid approach to product development by using the FreeForm system for organic shape design and Pro/E for geometric and mechanical design," said Bob Steingart, SensAble's VP of Marketing. "Our customers are seeking even greater interoperability to expand the value of both systems to design and manufacture a broad range of products."

SensAble will be demonstrating the FreeForm modeling system as a PTC Enterprise Software Program partner at Booth #503 during the event. For more information on the PTC/USER event, visit http://www.ptcuser.org
