Hi @Gijs I’ve been using your fabulous GEC tool again recently after a while. It’s been really useful and quite easy to use. I’ve noticed that some edges are failing G0 with some really high deviation values! Like edge no.22 in the attached file reads as being over 4mm out! Looking at the geome…

@sach I’ll have a look at the file tomorrow, but in general keep the G0 filter as low as possible. Let me know if the info on this page makes it clear or not: Global Edge Continuity Analysing continuity of multiple edge pairs

@Gijs Very helpful article – thanks. Noted about keeping the filters in check.

@sach In this case it was not the filter setting. The reason you get big deviations is because I currently don’t handle split edges very well. The trimmed surface has a split edge, while the longer fillet has not. For now you can solve this in two ways: Split the edges of the fillet at the same …

Excellent – thanks. Will keep that in mind. Otherwise, the tool is great.

GEC doesn’t find the common edge in this example: [image] 2026-01-14_PatchFail.3dm (3.3 MB)

Try increasing the U and V spans of the patch. [gfhhhh]

[image] Brv: Try increasing the U and V spans of the patch. I want to analyze something that I have built, not build something different in order to be able to analyze it…

@Charles the analysis of that edge does not meet G1 conditions and is therefore the edge is not shown in G2 analysis. You can however see the edge in G1 analysis mode. We can of course debate if this design choice is a good one, as it apparently is confusing.
