I’m having accuracy issues with Refit trim on the below surface. One side re-trimmed ok. the other just won’t retim nicely. ICEM Surf did it with no problems though. File below… [image] Refit_trim_issues.3dm (79.0 KB)

Hi Rob, thanks for this example. RH-70065 RefitTrim - example -could be closer -Pascal

Just had a go with the new refit trim and think I’ve stumbled upon a bug with the new ‘degree altering’ function (by the way thank you for that!). It seems to be creating a small sliver of a trimmed surface as the result of the refit trim. Only happens when you tinker with the degree value (from my…

Correct, I’m increasing it from degree 3 until I get an ‘acceptable’ deviation. I haven’t tried starting with a higher degree and then dropping it though.

Thanks, I’ll do some more testing and report back. Lowering the degree is not an option btw.

As for your other file, the edge you try to RetrimFit, contains 5 separate edges, of which two are very short, I cannot merge the edges. It needs to be a single edge. If I DupEdge those edges and rebuild the resulting curve, extrude that and make a clean trim, so that I get one edge, RetrimFit work…
