3D software called Pro-E. I have been fan of Solidworks for intuitive interface but too many of my partners uses Pro-E so I decided to learn a bit. Attended 3 day course and of course still not sure if this one is for me or not. To me all the 3D software has good and bad but Pro-E is in a way slowest to evolve to new phase. But at the same time if they evolve too much then die-hard old user might get lost and omplain. This experience tells me how important is to come up with brilliant method in the beginning. Filing system which saves new one everytime is kind a lame concept to me.
