Drawing-to-Parametric-CAD

Drawing-to-Parametric-CAD turns a 2D drawing or hand sketch into a proper FreeCAD .fcstd file, not dead STEP geometry. Existing text-to-CAD tools output STEP with no sketch or feature history, so dimensions cannot be edited, drawings cannot be regenerated, and mold-production changes are impossible. This tool asks questions when a drawing is ambiguous, then builds a parametric Body with named sketches and features, verifying each sketch as it goes. Meta's Muse Spark model reads the drawing and writes the parametric macro; FreeCAD executes it locally. STEP is only an export. Verified on three parts: a gear (single valid solid, 2805.07 mm³), a harmonic-drive unit (2618.891 mm³), and a bracket (36.514 mm³, slots exactly 0.500 mm wide).
