The surface is non-planar. I've created the profile on a 3D sketch.
I tyring to use cut extrude to create and indent on this surface.
The cut must be uniformed at 1.5mm.
When I set to:
I get thinning over the top flat surface which is not my intended result I'm after - I also want it to cut 1.5mm down from the flat surface:
and also a cut outside the curved surface on the other side:
How can I perform this cut?
I also intend to use the split feature later on as I want to reuse this cut surface later on as the lid for another part.
What's the best way to do this?
