Would love to be able to do a SEO "intersect with offset" for adding curbs and sidewalks to a site mesh, fences that follow mesh contours, etc. Elements would automatically modify themselves if the mesh is modified.
For the target element, the command would be something like "intersect, then add 6" in the z-direction".
I would use this in making site models of hillside sites. It would avoid the need for duplicate meshes to elevate up and down, and would avoid the need to perform a second SEO operation to clean up the top surface of the intersection.
I can also imagine use for trim to follow free-form shells and roofs, etc.
