What it looks like

What is inside

DWG & DXF that round-trip

Reads and writes DWG/DXF from R12 through 2018 with its own native engines — no converters in the middle. Output is continuously verified against AutoCAD® itself.

Real 3D solids

Boxes, sweeps, booleans and friends are true 3DSOLIDs other CAD applications open as solids — not meshes pretending to be them.

Speed as a feature

A GPU-accelerated viewport that stays smooth on drawings with hundreds of thousands of entities — pan, zoom, select, edit.

A workflow you know

Command line with the classic commands and aliases, dimension and table styles, layouts, blocks, AutoLISP scripting. Muscle memory included.
