Hi, is it possible to split the green arch in the screenshot into segments using the white lines? I've tried various combinations with polysplit (not working well inside foreach), using the boolean sop (not working at all as it tries to triangulate the poly), and using the labs boolean curve (again, tries to triangulate everything). Attaching the file.

Thanks, interesting assets, however I'm not looking to break up the line into dashes, I need to break up the shape into closed polygons I can then sweep profiles curves on.

you can use Boolean SOP in Shatter mode
just make sure you extrude your lines to form cutting planes

That's what I was missing, the cutters needed to be planes, thanks!
