A little bit about Blender 3D
The special thing about Blender is not really exclusive functions that are missing in other programs, nor is it an outstanding user friendlyness (in this point even most of the Blender fanatics will agree: User friendliness or intuitive operation is certainly not the first thing that would come to your mind to describe Blender).
Blender much more captivates in a completely different way: While most extensive 3D programs are not only extensive, but also expensive, Blender is a hundred percent free. Of course there are other programs that can do 3D and are free, but none of them get even close to the broad functionalities of commercial 3D programs. Blender on the other hand has close to every function, the commercial competitors have to offer, though they may sometimes be not that easy to find in the program layout of Blender.
