CADFather: Autonomous CAD Reconstruction through Coordinated Tool Use
CADFather coordinates tools and a vision-language agent to reconstruct editable CAD programs from 3D meshes.
CADFather is an agentic system that recovers editable parametric CAD programs from 3D meshes by coordinating complementary proposal tools. A vision-language assistant inspects renders, chooses which programs to extend and which tools to call, and stops when reconstruction is complete. Learned and algorithmic tools propose operations, numerical optimization refines parameters, and executed programs are scored as feedback. The authors report quality, validity, and cost trade-offs on DeepCAD, Fusion360, MCB, CADENA-Bench, CADBench, and BenchCAD without extra training.
- Coordinates vision-language decisions with CAD tools and numerical optimization.
- Uses pretrained models without additional training.
- Evaluated on DeepCAD, Fusion360, MCB, and three CAD benches.
- Maintains alternative candidate programs and the best valid result.

Reconstructing an editable CAD model from a 3D shape remains a challenging engineering task. Existing methods can propose CAD operations, but no single source of proposals works equally well across different part geometries and stages of reconstruction. We introduce CADFather, an autonomous agentic system that coordinates complementary tools to recover parametric CAD programs from 3D meshes.
