Prompt library

Copy a request, paste it into Claude and change the numbers to yours. Claude does the work in the CAD program that is open on your PC.

1. How to ask

  • Say what to do, on which part or feature, and with which numbers.
  • One job per message works best; you can chain the next one after it.
  • Attach a drawing, photo or PDF when you have one: Claude reads it.

2. Build a model

Make a steel plate 200 x 120 x 10 mm with four 9 mm holes, 15 mm from each edge, and save it as Base Plate.

Build a welded frame from 40 x 40 x 2 box section: 1200 long, 600 wide, 750 high, with four legs and a cross member halfway up.

Make a stepped shaft: 30 mm diameter for 50 mm, then 40 mm for 120 mm, with a 1 mm chamfer at both ends.

3. Change a model

Change the plate thickness to 12 mm and update everything that depends on it.

Make the frame 1500 long instead of 1200; keep the legs at the corners.

Set the material of every part to stainless steel 304 and tell me the new total mass.

4. Drawings

Make a manufacturing drawing of this part: three views, an isometric, all dimensions, tolerances and the title block.

Make an assembly drawing with a parts list and item numbers.

Add a section view through the holes and dimension the hole depth.

5. Export

Export this drawing to PDF in the same folder.

Export the flat pattern of this sheet-metal part to DXF for the laser cutter.

Save this assembly as STEP for our supplier.

6. Ask about your model

What is the mass of this assembly and which part is the heaviest?

List every part with its material and quantity.

Which fit should I use for a 25 mm shaft in a ball bearing?

7. Your own rules

Remember: our default material is S275JR unless the drawing says otherwise.

Remember: bolt holes on our frames are 9 mm for M8 unless I say otherwise.

Show me the rules you have saved for me.

Keep our CADbyAI rules in the shared folder \\server\CAD\CADbyAI so the whole team uses them.

Saved rules stay on your PC, or in your company's shared folder so a broken PC loses nothing, and apply every time. New to CADbyAI? Start with the install guide.
