      SketchUp vs Autodesk Inventor opinions
      This alternative is disputed. SketchUp is still a legitimate alternative to Autodesk Inventor, but it might have issues that some users think are important.
      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

      3d vs 2d. the end results of printed plans may not be too different but there's a large difference in use and also some different purposes for use.

      It's easy and fun to use. It can even make stop motion animations if you manage to find out how! If you want a free and easy alternative to Autodesk Inventor, then this is for you. (It's also suitable for 3D Printers!)
