Single source of truth: build123d drives BOTH the STL preview and the STEP export from the same script + params, so what you see is what you download. Verified live: generate → build123d → /api/build STL + /api/step STEP. - prompts: SYSTEM_PROMPT teaches build123d (Python) with # @param sliders - claude.ts: parse python fences - step.ts → generic geometry-service client (/tessellate + /step), GeometryError carries the Python traceback for the repair loop - worker: /api/generate returns code; /api/build tessellates; /api/step runs the same code+params (no separate Claude re-gen) - client engine: runJscad → buildModel (server STL); parseParams handles # @param - App: debounced param rebuilds + rebuilding indicator; STEP sends script+params - Viewer: Z-up→Y-up rotation; retire client-side JSCAD worker - VM service.py/runner.py: /tessellate + /step with params Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The model code must assign the final solid to `result`. A `params` dict (parsed
|
|
from <params_json>) is injected into its namespace so parametric sliders work —
|
|
the same code powers both the STL preview and the STEP export, guaranteeing the
|
|
preview matches the download.
