Version 16 is now available although we haven't got it yet here at Box Hill TAFE in Melbourne Australia. A new feature is frame construction which works in a similar way to XpressRoute, the piping and wiring application. There is an article on the CADalyst web site

Apparently you then take the frame into the weldment environment and weld it up. Sounds like a good exersize, I'll have to redraw.
