I would like to see some of the inventor fusion tools in the Inventor professional to make changes more quickly to the model, there should be in an other section call fusion for example.
a quick F8 ortho to make orthogonal lines like AutoCAD.
The loft with two rails not always works to make surfaces.
Repair environment that can fix the model automatically.
automatic ballons insertion.
The ability to make laser cut sheets of a 3d model.
