It can be convenient to use the same part numbers for the drawings of a specific part or assembly. With the correct settings, Onshape will automatically number drawings for you.

Release Management Settings

There are two important settings in the Release Management section necessary to have Onshape automatically generate drawing part numbers. 

First, set Part Number Generation to “Sequential part number generation”. Without this on, the button to generate part numbers will not be available. 

Additionally, set Part Number Uniqueness to “Drawing can reuse part number from an assembly or part in the release”.

Generating Part Numbers

When in a Release candidate, select the “Generate missing part numbers” button in the header of the Part Number column. Any drawings with a blank part number automatically populate with the associate part or assembly number.
