You can try to use chunk() from PolyProperties. For a generic oriented line, you have to rotate the polygon using the line orientation, apply the chunk() function about an axis, and rotate back the polygon. ![2023-05-26 13_34_42-SMath Solver - [PolyProperties.sm_].png](/forum/resource.ashx?a=47127&b=2) Edited by user 26 May 2023 14:40:11(UTC)
