## Summary

Kern says that asking Claude to build a robot cat from one picture produced a toy-like model after eight rounds. He reports that switching to four flat orthographic drawings, with an open 3D model making the body and Claude handling plates, details, rigging and rendering, produced a 471-plate robot cat. The article gives the full pipeline, prompts, costs and mistakes.

Claude can't draw. 8 rounds of code and my robot cat was still a toy.

Then I gave it 4 flat blueprints instead of 1 picture. 471 plates, 132 parts, a drop test with real numbers.
