PTC to Accelerate Integration of FiberSIM with Pro/ENGINEER

WALTHAM, Mass., November 15, 2000 - PTC (Nasdaq: PMTC), a leading vendor of mechanical computer-aided design (MCAD) and collaborative product commerce (CPC) solutions, today announced its extended partnership with Composite Design Technologies, Inc. (CDT), a market leader in creating CAD-integrated software solutions for designing and manufacturing composite parts. The purpose of the augmented partnership is to accelerate the integration of the composite design tools of CDT's FiberSIM software with PTC's powerful Pro/ENGINEER software in order to deliver a complete composite design and manufacturing solution for Pro/ENGINEER users. Currently, CDT and PTC's products are integrated to enable composite parts to be accurately and efficiently manufactured. The new integration will allow engineers to quickly and easily design parts in a composite engineering environment to take advantage of the unique characteristics of composite materials and to optimize part performance.

"CDT's expertise in composite engineering software makes it the ideal partner for extending Pro/ENGINEER's composite design capabilities," said Jon Stevenson, executive vice president and general manager, MCAD at PTC. "The new tools that we are developing in the partnership will provide a complete solution for composite design, analysis, documentation, and manufacturing. In addition, the solution will be implemented in a manner that capitalizes on the key strengths of Pro/ENGINEER. Our development teams have been working closely to provide a composite solution that is truly parametric and associative in nature, allowing automatic updates and a smoother workflow."

"We are excited about the extended partnership between our two companies and look forward to the opportunity to build upon our four years of experience with composite manufacturing inside Pro/ENGINEER," said Steven Luby, president of Composite Design Technologies, Inc. "By collaborating with PTC we will be able to provide solutions that streamline the composite engineering process by speeding both the design and manufacture of composite parts as well as by providing the feedback that is necessary to maximize the inherent benefits of these advanced materials."

"Pro/ENGINEER is an industry standard, and our partnership with PTC enhances our ability to deliver world-class composite solutions to many more manufacturing companies," Luby continued. "Our jointly developed solutions will further automate our users' composite design processes, and will allow engineers familiar with Pro/ENGINEER to use the new software intuitively."

Advanced composites are becoming indispensable for improving performance in aerospace, automotive, industrial, sporting goods, marine and medical equipment industries. Composite components and designs are particularly important in the aerospace industry, where the high strength and low weight of the materials allow for increased performance at a reduced cost.

FiberSIM and Pro/ENGINEER will provide users with an environment that links composite design, analysis, tooling and manufacturing. Using a unique material simulation technology that predicts how composite materials conform to complex surfaces, these tools enable engineers to concurrently balance part geometry, material, and process constraints. By using FiberSIM with Pro/ENGINEER, engineers can visualize fiber orientations, predict manufacturing problems and take corrective action during design. This results in shortened product development cycles and improved part performance.

About FiberSIM Composite Engineering Solutions

FiberSIM is a suite of software products that transforms CAD systems into high performance environments for designing and manufacturing composite parts. The FiberSIM product suite includes tools that automate the design process, assess the producibility of a part, and generate manufacturing information including documentation, flat patterns, and data to interface with laser projectors, automated cutters and fiber placement machines. Consequently, FiberSIM enables users to drive all aspects of preliminary composite design, analysis, detailed design, and manufacturing from within a single CAD master model.
