A CAD operating system

Same tree. Mesh or SDF.

Every boolean tree in Rig Cad can run as watertight Manifold mesh or as an SDF. Stay in mesh for crisp solids and export. Switch to SDF when you want smooth union blends, soft fillets, and field-driven detail — same parameters, same structure.

One tree, two backends

Mix Manifold mesh and SDF freely

Mix freely: evaluate any part of the tree as SDF for soft blends, then continue with Manifold mesh operations for crisp cuts and hard edges — one parametric model, not two workflows.

Visual parametric workflow

Edit the CSG tree visually

See every CSG component in the tree and edit it visually — then evaluate as mesh or SDF depending on whether you need sharp features or soft blends.

Frequently asked questions

How is Rig Cad different from FreeCAD, OpenSCAD, or Onshape?
Rig Cad runs fully in the browser with multiple geometry kernels in one parametric project tree—solids, surfaces, meshes, and implicit SDF—plus shareable configurators and print-ready export without installing desktop software. Unlike tools locked to a single representation, the same CSG tree can be evaluated as mesh or SDF, so smooth blends and hard booleans live in one parametric model.
Can one project mix solids, surfaces, SDF, and voxels?
Yes. Different subtrees can use solid CSG, NURBS, implicit fields, or voxels in the same scene graph, connected through parameters and a shared workspace.
Can someone customize a design without learning CAD?
Yes. Owners expose selected parameters so visitors open a configurator, change the options, and generate a tailored model. Visibility, forking, and download permissions stay under owner control.
Does Rig Cad require installation? Do my files work offline?
No install is required—Rig Cad runs in a modern browser with WebGL. Projects save locally in the browser and sync to the cloud when you are online, so you can reopen recent work offline.
What formats can I export for printing or CAD exchange?
Common print and mesh formats include STL, 3MF, OBJ, glTF/GLB, and PLY; 2D workflows use DXF and SVG.
Is Rig Cad free to use?
Yes. You can start free in the browser. Upgrade when you need more private projects, storage, collaboration, or higher compute limits—see plans for current free and paid tiers.

Export for the next step: STL and 3MF for printing; OBJ, glTF/GLB, and PLY for mesh interchange; DXF and SVG for 2D.
