Rhino WIP has a completely revamped Patch command. [Patch-FillSrf | New in Rhino WIP] What is Patch? Patch takes a set surface edges, curves and points as input constraints to create a multi-sided patch with positional (G0), tangential (G1) or curvature (G2) continuity to selected edge…

A next example for a nice result: [image] CP_2025-05-12_FillSrf.3dm (1.5 MB) The original black polysrf shall be replaced by a single srf without much effort. I used the duplicated border of the original srf and some projected points for the internal constraints. Why is the tolerance for the i…

Makes sense, I’ve made a ticket for that https://mcneel.myjetbrains.com/youtrack/issue/RH-87391 While that is not yet possible: a scaling by 0.01, FillSrf with boundary tolerance also divided by 100, but internal tolerance left unchanged, follwed by un-scaling by 100, could already help maybe? [i…

[image] Menno Deij - van Rijswijk: scaling by Why didn’t I think of that? :melting_face: This gives the expected result, great. Scaling is good for an intermediate test, but I’d still prefer free access to the tolerances. Or restricted by a bounding box factor or whatever.

[image] Charles: free access to the tolerances Yes, this will come when the ticket has been done.

ExampleX.3dm (545.5 KB) This Was done with Xnurbs. The 6 sided hole. I found it to make a better match than the new fillsrf. just putting it out there. Thanks for the work you’ve done.—Mark

I see what you mean. By default, FillSrf tries to meet the document absolute tolerance for the positional constraints and the document angle tolerance for the normal constraints. Your document has quite strict tolerances that increase the refinements of FillSrf unnecessarily, ultimately not giving a…

Trimming fails in this combination: [image] [image] CP_2025-05-14_fillSrf_trim.3dm (909.5 KB)

Correct, trimming is only supported in cases where a single, closed trim-loop is present, made from G0/G1/G2 border constraints. Having surface edges as internal constraints with continuity is an existing feature request. Right now, it should be possible to trim the result obtained with the constra…
