what is the easiest way to delete a hole in a non-planar face/surface without having to recreate it from scratch (this last bit is important for my process).
So essentially going from the first image to the second:
Some other cad programs have specific commands that would delete a hole or a face and patch it based on the surrounding faces - solidworks has a DeleteFace command that does just that. So I’m wondering if there’s something similar in rhino.
You can just Untrim the hole.
Let’s make clear what’s going on here, and this applies to Rhino, SW, ALL CAD systems. Putting a hole in a surface doesn’t actually REMOVE anything from it, it ADDs a “trim curve” to the surface, telling it to show show the bit inside and make an edge you can build off of. The actual underlying surface is unchanged. This is the killer feature of NURBS, why all attempts to dethrone them have so far failed–with meshes, subdivision surfaces, etc., putting a hole in an object(ignoring history features) absolutely massively changes it, the hole is actually “gone” and the remaining area probably doesn’t even match up with the original.
Thank you Jim!
On another note, do you know if there’s an Untrim method in rhinoscriptsyntax api? I can’t find one in the documentation.
The short answer is yes it’s possible to untrim edges with code…
