cad-human-loop

To add human-in-the-loop checkpoints to parametric CAD, this skill uses a script-first workflow with build123d or CadQuery, pausing at visible progress points to export PNG previews and parameter tables for human review before finalization.

Script-first parametric CAD uses maintainable code to generate designs, preventing silent finalization by enforcing visible progress artifacts and human-in-the-loop review checkpoints before the model is completed.

Yes, you can use FreeCAD as a review surface to inspect and intervene in parametric models. The skill exports STEP artifacts that are compatible with FreeCAD for detailed human-in-the-loop review.

During a script-first CAD workflow, the skill exports PNG previews for visual checkpoints, STEP files for geometry inspection, and parameter tables to document the design variables for human review.

Yes, the skill provides plugin-friendly packaging that allows you to organize multiple script-first parametric CAD workflows into scalable collections for maintainable and reviewable coded design.

The approach requires exporting intermediate artifacts like PNG and STEP files at each checkpoint, meaning the human-in-the-loop review process is manual and necessitates a separate review surface like FreeCAD to inspect the generated geometry.
