Because it uses true curves, Inventor uses a lot of RAM and can crash when you are assembling complicated parts. Inventor works fine for small simple projects, but it's slow-going to make something in it. Google SketchUp doesn't require that you place a sketch, then draw, and then extrude the sketch, and it works just fine. But, based on what I have used Inventor for during the better part of a decade. I already know that I don't use even a small fraction of what Inventor is capable of and that I can only review the limited number of tools I have used. This works out well because I tell my students that by the end of the class I teach, they will be able to create an assembly instruction book that is just as good as anything IKEA would give their customers. The images it makes is just as good as anything you would find in IKEA assembly instructions. Inventor is very good at turning a part file into both assembiles and working drawings. I have a feeling that students using Inventor in their Introduction to Engineering Design class is a huge majority of where Autodesk Inventor is used. I am an engineering teacher and my students use this program for the entire second-half of the school year. If, on the other hand, you want to 3D a missing keyboard key or the insert to your tape dispenser, then Inventor is for you.

It is also not meant for animation, so being good at Inventor probably wouldn't get you a job with Pixar or Dreamworks. You would not want to design a house or perform city planning on it. Inventor is good if you are rendering parts to a small product. Because of the detail and accuracy in the renderings, it goes through a lot more RAM, but makes great images and working drawings. While it has animation tools, they're not great. It makes parts, assemblies, and drawings well. It is really good at that and not much else. Inventor is meant to be used to design parts of a mechanical machine.
