If only I could find a good vector graphics program for Linux that would put dimension lines on the blue print, I could eliminate windows all together. But I can't. Draw plus is the best program I've found to draw blue prints for the machine shop even if I have to use Windows in VirtualBox to do it. AutoCAD products are too complicated and are not user friendly. Draw plus is easy to use so for what it's worth, I use DrawPLus X8 and it gets the job done.
