How the PatentFig AI workflow runs

Start with the source, generate a controlled figure, review the result, then export only after validation.

1

Start from the strongest source

Use a clean product image, clear sketch, or focused prompt so the first output has less ambiguity.

2

Refine only what changed

Regenerate a view or adjust details instead of restarting the full drawing set.

3

Export after validation

Keep editable masters until composition, numerals, views, and file formats are stable.
