Subassembly Problem

[As-Built_Sigurd]

Hi guys,

I’m struggling with a subassembly I’m trying to build. I’ve tried a bunch of iterations but there always seem to be errors.

Essentially I’m trying to build a shoulder slope to attach to the overlay subassembly with undercut benching where required. There are three variations I’m trying to achieve.

I think the main problem is trying to determine the slope direction of the existing surface, where in Subassembly Composer the surface is always a horizontal line. When I move it up and down it changes the subassembly and sometimes removes the bottom bench.

Attached is one of the best (which isn't saying much) subassemblies I could manage and a few pictures of some cross sections where it did behave as expected.

Any help is appreciated.

Thanks

Can you post some pictures of it working and breaking?

Attached are some images of the issues I'm getting, and an ideal solution with an additional subbase layer (but I at least want to get the bottom benching sorted). And the latest dog's breakfast of a subassembly is also attached. I think the main problem is that if my slope to surface is not working it mucks up the whole thing, even though I tried to have an "isvalid" decision to deal with it. I imagine loop  geometry should come into it at some point so it's not so unwieldy.
