Subtracting a raised and curved terrain model from another

Create a hole! (tick....boom).

Do you mean ~something~ like in the attachment? If so, and especially with meshes, it may be easier to create a jpg of the same area and apply it as a material.

I know what you mean mate. You should still be able to do it with a material. I once created a material for a very odd shaped site and it seemed to work as expected. It just takes forethought when mapping the material. See the attachment.

Otherwise I fear you will have to use your favorite hole method and spend a lot of time readjusting all those funky mesh points.

Good luck.

What about using solid element operations to "make your hole" and also to subtract the edge from the border, and then save as a library part?

worked for me first time

Just duplicate the mesh, trace the shape with a fill, offset the fill 50mm or what ever you want your border width, then select the mesh, click on a node, select the "subtract from polygon" button in the pet palette and magic wand the fill. done

Good luck

Aye Corumba! I thought that's what you tried the first time and had no luck!
