From words to manufacturable geometry.
Describe what you need. kernelCAD designs the part, checks it holds together, and hands you a file your shop can manufacture.

Three steps from idea to part.

Connect your agent
Add kernelCAD to Claude, ChatGPT, Codex or Cursor. No agent? Use the one built into the app.
Connect your agent → -
Describe the part
Say what it must do, its sizes and the parts it must fit. The agent writes editable .kcad.ts source and runs a deterministic review of the geometry with review_cad.

Download or print
Open the checked model, change a size, then download STEP or STL for your shop or your 3D printer.

Make the dimensions part of the conversation.
Generate a drawing from your model, review each dimension and hole callout, then export a vector PDF. Choose baseline, chain or symmetry dimensions and save your sheet and projection preferences in a drafting profile.
Follow a mounting plate and a bearing mount from editable source to dimensioned views, datum references and a section through the bore.
