Demos

Real parts, built by the kernel an AI agent drives.

Engines, machines, printed parts and circuit boards. Open one, turn it, slice it, download the STEP.

Generative CAD

From a sentence to a STEP file.

Type what you need. The agent builds the solid, runs the shop's rules on it and hands back the part, the drawing and the STEP.

You ask
“Make an L-shaped sheet metal bracket 0.125 inches thick with 4 mounting holes. Do a manufacturing design pass.”
The agent calls
  1. cad_sheet_fold one bend, real bend face
  2. cad_drill_hole four clearance holes
  3. cad_dfm_check laser + press-brake rules
  4. cad_sheet_fold rebuilt at the shop's radius
  5. cad_design_review A3 sheet and DFM packet
  6. cad_export_body STEP AP242
You get The finished sheet-metal L-bracket with four mounting holes
