that seems like a little much to expect from an LLM; the average CAD file in my experience has not been not well-architected :)
as long as the output is something my manufacturer can understand (downloadable mesh: STL/STEP/etc (they dont take links)), the tool did its job for me
i would probably start the final model from scratch no matter what the output was, so i can match my chosen manufacturer's tolerances/design rules/optimizations, and to give breathing room for my quirks/workflow (i like to design subtractively, some people design additively)
