I need to put this horizontal pattern to a vertical surface. Can you help me?
Post your stuff (I would strongly recommend to do that always).
Other than that … SrfMorph does that (it doesn’t if the target is a poly surface). If your stuff is flat the guiding box MUST have some volume. Note: target surface (NOT a BrepFace) can be anything (flat, curvy, open, closed etc etc). Note: if you want to do someting on a target Brep you should map the curves first on some suitable BrepFace (as Surface) OR (way better) prepare flat “tools” in 3d, then map them and then do some boolen opp.
