I fiddled around a bit more. I have 3 modules, Main, Bottom and Fill. I can use F5 successfully with all 3 modules invoked. For F6, it dies if all 3 modules are invoked, but Main by itself is fine, and the combination of Bottom and Fill is also fine. So, it can create the geometry, just not all of the geometry together. I import() an STL in Main. On 6/10/2026 9:55 AM, Jon Bondy via Discuss wrote: I'm not sure what to do now. I did flush the cache, to no avail. Parsing design (AST generation)...
