Pro E is an unforgiving program while Inventor is quite the opposite. I have to learn Pro E for one of my design classes in college after using Inventor for almost three years and I want to punch the screen every time I use it. The only thing I have found so far that Pro E handles better than Inventor is the placement of datum/work planes. With that said Pro E will not work well unless you have a thorough understanding of setting up references within your drawings.
