Make me a keychain that holds a ¼" hex bit.
01 · Describe itNobody drew
this part.
Describe a part. Claude asks a few questions, models it in FreeCAD or AutoCAD, and checks its work before you print.
It starts with
a sentence.
No sketch and no CAD skills. You say what you need, Claude asks what it has to know, then builds the part in real CAD.
25 or 50 mm long? Snap it in, or friction fit?
02 · It asks firstPocket measured in the model: 6.55 mm across flats. Exporting STL.
03 · It checks, then exportsReal CAD,
not a picture of it.
AdderCAD connects Claude to FreeCAD and AutoCAD. It drives the real application, so what you get is a real model you can open, edit and print.
Asks before it draws
A few questions up front instead of a wrong part and a redo.
Measures its own work
Every dimension is checked in the model before anything is exported. Each edit is one undo step.
Runs on your machine
It drives the CAD install you already have. Your drawings stay put.
- Drives FreeCAD · AutoCAD
- Exports STEP · STL · DXF
- Works in Claude, via MCP
Nobody drew these either.
Each one started as a sentence. Every image is rendered from the real model.
