Hi,

I'm new to MoI and 3D too, so I tried to do this exercise.

I think the problem is after the extruding operation: for an outside fillet one must boolean/union the two or more faces where the fillet is to come. That means that after selecting the model you need to click again on the body to select the face and then click on the extruded faces, do a boolean union and only after this you can fillet.

The fillet itself is very small (1mm at the most).

I find the filleting in MoI not very intuitive..

Hope this helps.
