What T3D does

Three ways T3D moves you forward.

Built on TopMod's topology kernel, for the real modeling and fabrication work you already do.

Model topology, directly.

TopMod's DLFL kernel keeps every mesh a valid 2-manifold, so you can punch handles, weave surfaces and add holes without breaking it.

TopologyInsert and delete edge, extrude, handle, crust, wireframe, remeshing.
GeneratorsGyroid, TPMS, Voronoi, metaballs, chain mail, woven tubes, mazes.
StackLayers and a non-destructive modifier stack you can reorder and bake.
Bejewel · gems on every face

Test it before you make it.

Run air over a form, load it and see where it bends, and check walls and overhangs before anything goes to a printer or a shop.

AeroA wind tunnel with streamlines around your mesh.
FEAStress analysis with a live heat map.
ChecksCurvature, wall thickness, overhang, interference, section plane.

From mesh to material.

Every form can leave as a print, a cut file or flat parts with joints.

PrintBed preview, tree supports, split, drill, voxelize.
Sheet + plyPapercraft unfold, plywood layers with dowels, finger joints, waffle slicing, nesting.
ExportOBJ, STL and STEP for 3D; DXF and PDF for cutting.

AI empowered by Claude

Describe a form. Claude builds it.

Ask in plain words. Claude plans the form with T3D's own primitives, modifiers and generators, and every step lands in your scene as a live, editable mod.

How it works

«Add your own Anthropic API key in the app. Every step Claude takes stays a mod you can edit.»

Research

Built on real research

TopMod was created by Dr. Ergun Akleman and his students at Texas A&M University. T3D keeps all of it and carries it to the browser, the phone and Rhino.
