My cheap trick is to fill in the pesky triangle with a couple small chunks of slab, each one a little shorter than it's neighbor. I stick them on a layer like "roofs" which is hidden except for when I am doing 3D modeling. Maybe some day slabs will trim to roofs at an angle<BR /> <BR /> bill (pleased with self) roslansky</T></DIV> Tue, 23 May 2023 13:32:23 GMT https://community.graphisoft.com/t5/Modeling/cheap-trick-roof-and-slab-intersection/m-p/96064#M50406 Anonymous 2023-05-23T13:32:23Z https://community.graphisoft.com/t5/Modeling/cheap-trick-roof-and-slab-intersection/m-p/96065#M50407 They already do if you use Solid Element Operations.

Bring this 2D object to the Front. I do not use patches (are they still used), but if SEO is not an option than using patch might be a solution in some cases.
