Extrude bug

When I extrude the curve in the attached file with ‘split at tangents = yes’ the result is split at only 3 of 4 tangent intersections.

cant split when extruding.3dm (563.1 KB)

Hi Peter - I get that from Gumball extrude and not from ExtrudeCrv - is that what you see?

Maybe I’m misunderstanding your reply, but if I use gumball extrude, the part is split as expected (as if splitattangents=yes), but when I use extrudecrv with splitattangents=yes, the result is split at just 3 of the 4 tangent points.
