Ten CAD Challenges
March/April 2005 (vol. 25 no. 2)
pp. 81-92

The computer-aided design (CAD) industry has reached a significant plateau. A few large companies dominate the marketplace and provide excellent systems for a targeted clientele. A number of smaller companies understand how to provide functional extensions that make the systems better for specific user communities. This article discusses the most significant technical challenges the CAD industry and the research community face today. We take a further step and present an approach to addressing the challenges in a way we believe will improve CAD systems' effectiveness and, more importantly, make results accessible to a larger user community.
