So after an intense period of learning, I managed to design a trippy ashtray! I created it in Grasshopper, baked it and that did a few “manual” adaptations in Rhino. Each one of these is a separate Solid. How could I close this all up in one single solid that is “filled” and not hollowed out? I tried to do a “Solid Union” on these cubes but I get a “Boolean Union is set empty” error.
I imagine that maybe there could be gaps between the cubes so that’s why it is not working? But also I imagine I first need to create a base in the shape of the bottom row.
