I'm liking all the input we are getting here. I'm too busy to ready through this now, but I'll catch up with it on the weekend. I'd like to just list the candidates that are out there so none will be forgotten: Cascade Varkon QCad Freecad Free-cad Tomcad Please add any discussion candidates that I have forgotten. Ideally someone should make up a table with each candidate's programming language, state of completion, benefit to the effort and drawbacks. Kim > > -- > Kim Lux <lux@xxxxxxxxxxxxxxxxxxx>
