    Inventor is significantly more detailed and allows for the simulation of motion. Sketchup is a pretty rudimentary 3d drawing tool, and does not produce very high quality models or measurements, etc.

    Sketchup is very inaccurate compared to Inventor. While it is a good beginners tool, it cannot be used to make accurate engineering solutions

    Old software, each part of the model has to be entered in plain text. Can still make some nice stuff if you spend time learning how to use it.
