I got the Turbo CAD, Design CAD 3D Max. My opinion it sucks! I guess if you do CAD every day, it may work, To me the program is like killing flies with a shotgun, It has a lot of horsepower for major tasks. But for simple ones, it seems cumbersome for simple 2D drawings. I downloaded QCad and at this point I could figure out how to use some of the basic functions in a few minutes. In DesigCad I spent several hours trying to figure out basic functions. It has been a while but I have some contact with some CAD programs and 3D modeling.
