Writing better prompts

The AI is only as precise as your prompt. This walkthrough covers the prompting patterns that get you a usable model on the first try.

Before you start

1
Lead with the base shape and size
State the overall form and dimensions first — a 100 x 60 x 8 mm plate. Give the AI the envelope before the details.
2
Anchor features to references
Describe features relative to faces and edges: two 6 mm holes on the top face, 40 mm apart, centered. Ambiguous placement produces ambiguous results.
Tip: Include units on every number and name the face or edge a feature belongs to.
3
Ask for one change at a time
When refining, keep each message to a single clear change. A paragraph of simultaneous edits is harder to get right than four short prompts.
4
Use the result to correct
If the model is off, describe the specific difference — the fillet should be 3 mm, not 5 — rather than restating the whole part.
5
Inspect the generated code
Open the feature's generated code to confirm the AI did what you meant, and hand-edit for precision the last mile of the way.

A repeatable prompting style that lands accurate, editable geometry with far less back-and-forth.
