Hey there,
I hope you guys are doing well, I am having this query regarding snapping things on the undulating surface, I know one hack to trim and patch the surface but sometimes that doesn’t work in some cases.
please share how to do it cleanly this thing.

Thank you!

Are you looking for the Project command?

No, because project command only project curves on a surface, I want to project surfaces and meshes.

Hello - in this case, you can get there by splitting or trimming a copy of the target surface from the top view.
