Hi Burr - the "sharp corners" part that I was talking about previously was actually meaning how multiple surfaces touch one another, not necessarily how the trim curves of one surface are arranged...

But yeah if you can post it I'll take a look - most likely it will be a case that is having difficulty with the geometry library's offsetter and probably not much that I can do about it directly but it is worth a check.

It will not be unusual to see failures with the new inset tool because the offset mechanism in the geometry library just has difficulties with many cases.

The Inset command internally uses solid offsetting a couple of times in sequence, so any difficulty in the offset calculation will cause it to fail.
