Turn a 3D problem into small specifications

zhuchaokn describes a practical workaround for generating a printable vacuum ramp: break the geometry into ordered steps, then let an agent execute those specifications in Blender. The question for other builders: is structured code a better interface than asking for a finished mesh?

Ive had great success with asking claude to use openscad for part design. Because it’s parametric design as opposed to modeling, it inherently lends itself to making it easier to build. Use metric units when prompting, and Ive even drawn sketches to add to context, and be surprised at how good the outcome can be!

modeling isn't the hard part. It's decomposing it into usable chunks, the knowledge of what's going to be a problem, etc. either way, give an actual CAD program like fusion a go. No, not the FOSS stuff- the real stuff. Although, some of them are "close, but no cigar" these days. Not like gimp which is an exercise in self-flagellation.
