Hi there!.

The filleting function doesn't report errors in the current beta version of MoI. It sounds like you probably set the fillet value too high. Try setting it to something low like 0.2 and see if that produces anything. If a low value works then you know that the surface can be filleted. So then it's just a matter of gradually increasing the value until you get the ideal fillet.

You'll find that on the odd occasion that the fillet function will refuse to fillet no matter what value you enter. I'm guessing that's because the geometry in the selected area is a little too complex.

Early days yet!.
