[QUOTE="ken"] Well, considering that GSS is not in the marketing/sales business for consumer products, but rather the business of building translator/viewers/integrations for the major CAD vendors, I would be more inclined to believe that SolidWorks has contracted GSS to produce the initial SolidWorks version and has been free to expand it for other applications since they own part of the copyright. FYI, SolidWorks has only 8 patents to their name and Edrawings nor any of the technology used within is listed. The only registered Edrawings item listed for them is the Edrawings trademark (which isn't a patent). JUST WANTED TO MAKE SURE YOU WERE AWARE.

For years they have also made CAM system toolpath engines. In regards to the orignial poster who asked if he should by Solidworks... No ! [URL="http://www.vx.com"]www.vx.com[/URL] jon
