progeCAD AutoCAD DWG Clone, 1/10th the cost, no need for conversion! no learning curve for AutoCAD users. AutoCAD Menu, Script, Font Compatibility, AutoLISP Compatibility!
I use the progeCAD program to design furniture that I build for my children and grand child. As a user of AutoCAD for many years the transition was easy and I enjoy all the program features. As a retired engineer I can not justify the cost of AutoCAD for my hobby use so progeCAD is an excellent alternate (in fact I like it better than the AutoCAD LT I was using on my friends computer).
