Align object along a plane

align object along a plane.3dm (108.7 KB)

Hi,
Does anyone know a direct command to align or project a volume tube onto a plane surface? I have attached the file in this post.

Dear @j.woo
your geometry is fare away from world origin - this will cause problems.
your document tolerance is 0.01 and the chamfer has the same size - this will cause more problems.

check the following commands to orient objects on a surface or a construction plane:
_orientOnSrf
_remapCplane
and many more here V6
