Hi Martin, that's definitely an interesting alternative. But the example you posted is actually kind of lumpy and not so great in that area, the surface has kind of gotten bunched together.

Here I've turned on the metallic lighting in MoI and examined your model. Notice these darker bands, which are actually little lumps in the fillet surface:






Compare that to this result created in MoI with radius = 3:






So not only does MoI allow you to go to a higher radius that ViaCAD is not able to reach, but also the surface generated for this particular case seems to be higher quality as well.

That's just this particular case though, there are quite a lot more cases where ViaCAD handles filleting better than MoI does, but not completely 100% of the time as this example shows.
