Autonaming

Autonaming generates unique Titles for new or existing SOLIDWORKS parts, assemblies, and drawings when you save them to the 3DEXPERIENCE platform. Autonaming does not change the original file names. The system administrator activates autonaming on the server side.

This information applies to SOLIDWORKS if you enable the Design with SOLIDWORKS app.
Autonaming is not applied to Toolbox or PartSupply files.

In the Save As New dialog box, you can change the autonamed title to be more meaningful. If autonaming is enabled, the file name retains the original autogenerated name.
