Great! That will be helpful, Michael.

I had what I thought was a strange fillet result the other day. I built a half barrel by extruding a semicircle along a straight path and then capped the ends using the 'planar' command. Then I joined the ends to the semicircular side and filleted the joins between the ends and the side. The fillet extended beyond the side (perpendicular to the inner curve of the fillet). By the way, the side and ends did not have any thickness ... just simple surfaces.

The only thing I could figure out how remove these tags was to make a cutting plane flat with both edges of the curved side and larger that the whole object and then 'trim' the tags off. It worked but it was cumbersome.

I hope this makes some sense ... I erased the file afterward but I could recreate it, I think, if you would like to see the problem.

I am enjoying MoI ... I try to play with it a few minutes every day ... I think it will be a great compliment to my usual work horse, Rhino.

cheers
