Wirecut through a solid, in the shape of a flanged plate, will force the cut object to split at its creases or tangents. If I use boolen difference to cut through the flanged plate, it does not force a split. I have to disable creasesplitting prior to running any wirecut commands to preserve the par…

Is there a reason you want Crease splitting on all the time? The command does look at Crease splitting global variable.

WireCut is splitting tangent edges. Reproduce: extrude an L-shaped profile (flange + web). The inside and outside corners where they meet are tangent arcs — smooth edges, not creases. WireCut that solid. Expected: tangent arcs stay unsplit. Actual: the result is split along both tangent arcs. Wo…

Sorry, I am a bit slow. I understand your instructions, but need to look closer at the structure of the flange web object. On my tests I am having trouble getting the correctly split and not split objects to show the differences.

Maybe this can help us. profile extrusion wirecut.3dm (137.1 KB)
