Hi Jacobo, I'm glad you like MoI!

Thanks for sending in this bug report, especially with the IGES file so I could test it over here, that really helps a lot.

There isn't really anything wrong with the IGES file - this is a bug in MoI. It's actually a bug in the geometry library that MoI uses, it gets confused with certain surfaces that have one edge of the surface pinched together in a pole, if the pinched-together points are just not quite exactly equal to each other.

It would be nice if I-DEAS generated the poles with exactly equal points for those corner fillets, but they are only off by such a very tiny amount that it would be good for MoI to be tolerant of this situation.

I'll see if I can fix this up so it works properly, I don't think it should be too hard.

Thanks!
