Wish I had this back in college
This is a fantastic app for showing models in the design stage. It is true that you either need Archicad or know someone who has it to get your models into the app, or you can also walk around other peoples designs that you can download from the app.
If you use a autodesk product like revit, you are going to have to convert it into a 3ds file to import it into Archicad, which can create some problems. (this may not be true for the newest version of Archicad) so I like using sketchup for early design stuff anyway. I have not had any problems doing it this way.
I wish that I would have had this as a way to show my projects back in college.
