Thank you for that found. It’s working in Rhino 7 (not in Rhino 8 WIP) and it’s not giving me exactly the results I was looking for, but it’s alright good enough, it’s not something critical for me at the moment.
You can see that it’s not exactly a silhouette of the first mesh, and the second mesh since it’s disjoint might have a silhouette around the whole geometry or per disjoint piece - right now is per disjoint piece.
Another thing is that these lines are interfering with the geometry, it’s visible on some edges where silhouettes are thinner because they are occluded by the mesh.
Ideally, for the disjoint mesh, I would like to have 2 outlines, the first one around disjoint pieces and the second one around the whole mesh, and the second could be offset in the screenspace so it will not overlap.
But, that’s just my wish, I think it would be very cool to have, but I understand it’s not easy to implement or that important.
