Lesssetup
A physics-first CAD platform built to cut down hardware-to-simulation iteration time.
No Migration Needed
LessCAD acts as a lightweight and painless check that fits into existing workflows. Import your geometry for fast, meshless physics with no per-run cost.

Signed Distance Fields
Physics setup has changed: 3D models drop into a solver grid with no mesh to build. This is the hard part that incumbents built on meshing won't touch.
Best of Both Worlds
Full .STEP interoperability: import from and export to the tools you already use. Our hybrid engine keeps an exact mirror between B-rep and SDF for every change, so CAM-ready exports come through intact.
Organic sculpts and lattices export as STL.
Road to Air-Gapped
GPU-native means LessCAD can run 100% offline. A local LLM drives CAD and physics workflows, all of which render and solve on the parallel processing power of GPUs. Built for sensitive industries where designs can't leave the building.
