I would really like to create windows/ doors/ objects etc. in an environment like the Profile Editor. I use it all of the time for profiles of walls/beams etc. Its easy to add stretch points, change shape etc. I could see creating an object in that type of environment would be a great benefit. That is probably what appeals to the folks that use Revit. The family editor is fairly straight forward to use. It is similar to the profile editor with additional capabilities. In Archicad you can do practically anything a myriad different ways but it would be nice to have a simple straightforward approach to object making.
