The ease by which I was able to create models with little effort. It's ability to handle large amounts of information without slowing down my computer. The lack of documentation at times.

If you're looking for a simple yet effective way to store your files in one place then this software will do just that. Not only did i find myself more organized but i realized i had so much stored away that would otherwise get lost.
