3DJ — Make an idea you can actually edit.

Design a replacement part, a mating bracket or a product concept. Start from a brief, a reference photo or an existing example, then edit dimensions beside the model.

Real CAD and creative meshes — two distinct paths

Script CAD uses OpenCascade B-rep solids with parameters, booleans, fillets and separate assembly bodies. Export STEP for CAD workflows or STL for slicing. OpenSCAD runs its own local engine and exports STL and source.

AI concept generation produces approximate GLB meshes. These are not automatically parametric CAD or STEP solids. Provider queues and shared GPU availability vary.

Inspect before you print

Check closed geometry, bed fit, overhangs and available wall diagnostics. Some results are sampled or unevaluated; no diagnostic certifies physical fit, strength or safety. Supply real measurements for photo-assisted parts and test the printed prototype.

Try a real example

Local starter editing and CAD exports do not require sign-in or a cloud GPU. JavaScript is required for the interactive workspace and initial asset downloads; a fully offline installation is not promised.

For AI agents

Discover the actual tool catalogue at https://3dj-neuraldeepnet.on.adaptive.ai/api/mcp. Local browser CAD export is distinct from server-side MCP operations; read each tool's result and permissions before promising an artifact.
