Pro-E is not a bad program its just not very intuitive (if your using WF3). I find solidworks gives you more freedom for conceptual ideation where Pro-E is very structured (making the program more robust). There are a few features in Pro-E WF3 that really get on my nerve such as not being able to extrude & draft (at the same time) over 40 degrees. The interface is not really to my liking as well (stupid drop down menu's)!!
