While looking for open source cad/cam apps I came across the website for OpenCascade. It's a open source CAD/CAM framework for building other applications. It seems interesting. Has anyone got any experience with it?

BTW, the website is www.opencascade.org

Thats a really good link you posted. I just went to http://www.opencascade.org/showroom/screenshots/
And are very impressed at some of the designabiliy it has.

Thanks for posting that. :)
