Solid Element Operations on Mesh indicate "Excluded" - no longer displays in 3D when using marquee

Scott Bulmer — Tue, 19 Dec 2023 04:50:57 GMT

In a site mesh I have performed many SEO subtractions basically to correctly represent excavation / grading caused by foundations, slabs and retaining walls. After a certain number of SEO operations on the mesh it stops displaying when using a marquee. The mesh can be displayed if selecting it by itself using the arrow tool. With the mesh selected then selecting the SEO button displays that some of the operations are 'Excluded.' See the attached screen capture of that dialog box.

Why is this happening and how can it be fixed?

Hi Scott, I always found meshes to be a bit "brittle", so to speak. You can break them easily – sometimes convex countours will already do the trick.

Same goes for SEO, especially lots of it. And by all means, it looks like you're deploying maybe just a bit too many for Archicad.

When I had a project with huge underground parking connecting half a dozen of apartment buildings the only remedy I found was to make morphs out of all elements, bool them and carefully clean it. The remaing morph was a solid piece, so I only had one single element doing the SEO subtraction.

It was no fun, it wasn't blazingly fast, but at least it worked.

Thanks Lucas. I used a version of your suggestion. One of the SEO operations was a double operation also known as the path to mesh technique so as to represent a road. I eliminated that double operation and instead created/placed a new mesh representing the road then subtracted down on the site mesh. All is working now. Thank you again. Scott
