Creating 3D models can be quite challenging. Applications like Cinema 4D and Maya are all-round 3D apps. They allow you to create 3D worlds and animations that can be used just as effectively in a game as in a presentation or blockbuster movie. Strata Design 3D CX 8.1.0, the Winter 2015-2016 release I got to review, is more focused on presenting 3D model design - objects, products, architecture, interior design... - in the most realistic and efficient way. The app has a learning curve, but it sure isn't as steep as Maya's or Cinema 4D's.
