not a linux article, but but we did have someone asking about catia features and costs. this will give you an idea. http://www.caddigest.com/subjects/solidworks/select/cadcamnet_catia.htm <snip> CATIA and SolidWorks are both feature-based, dimension-driven solid modelers running on Intel/Windows systems. They even look the same - at least superficially - employing Windows look and feel with menus, button bars, and graphical feature and assembly trees. Both are owned by the same company. Yet CATIA sells for $16,500 (2001 average) vs. $4,995 for SolidWorks. What do you get for the higher price? </snip> -- Oh, I have slipped the surly bonds of DOS, and danced the skies on Linux silvered wings. http://pfrostie.freeservers.com/cad-tastrafy/ //www.freelists.org/list/cad-linux
