It likes at version 11 we have a Qt4 widget for OpenCascade that now, pretty much, will render objects, and can load breps, iges and step. I've basically taken a week off, doing other "stuff".
I did have a plan and direction for an application, but I'd like to ask what direction you'd like to see it take. There seems to be many needs, such as CAD, FEM and geometry laboratories. What's you're thoughts?
