Field notes
The described workflow includes edits to feature type, nominal value, tolerances, quantity, and notes, with changes to the same drawing carried forward when reopened. Reports can suggest measurement instruments by feature and tolerance, and the page says default tolerances can be filled from national standards. The site also describes a rule manager for recording recurring corrections; these are product claims, not independently verified capabilities.
