Odd trimming bug

While helping someone on a different thread I came across a strange glitch when using the Trim Solid component.

Basically it won’t do anything. However, I baked the objects and internalized them back into GH and it worked ONCE.

After that it didn’t.

Hi René -

That’s a common issue with surfaces that aren’t aren’t split at their tangents.
If the surface was originally made in Grasshopper, you’d extrude the curve segments before joining them.
In Rhino, you can run DivideAlongCreases with SplitAtTangents=Yes on the surface, and then use the brep as input in Grasshopper:

Thank you @wim - the surface was made in grasshopper originally, but via lofting a bottom and top profile. However, this helps, thanks!
