forgecad-3d-reconstruction

Converting an STL mesh to a parametric CAD model requires staged source inspection to understand shape families and symmetry. This Skill authors real parametric ForgeCAD geometry rather than returning a simple import wrapper, outputting a runnable .forge.js model.

3D reconstruction scoring evaluates how closely a rebuilt parametric model matches the source mesh. It runs reconstruction scoring with alignment controls and iterates from coarse silhouette to localized features using metrics like RMS, p95/max, coverage, and bounds/volume deltas.

You can reconstruct a STEP or STP file into a ForgeCAD model. The Skill accepts existing 3D CAD or mesh files including STL, OBJ, 3MF, STEP, and STP formats, rebuilding them into a readable, parametric .forge.js model.

Validating reconstructed geometry against a source mesh is best done through evidence-based scoring and iteration. The Skill executes reconstruction scoring with alignment controls and uses returned metrics like RMS and coverage to iteratively refine the model from coarse silhouette to fine details.

Mesh to CAD conversion works with OBJ and 3MF files. The Skill accepts these formats alongside STL, STEP, and STP, performing reference-first inspection to understand shape families, symmetry, and key tolerances before rebuilding parametric geometry.
