Altium > Solidworks Issues

I have found a workaround, but it is a bit inconvenient:

Open just the STEP-file from a board in Solidworks and save it using Pack and Go where one can add an extra suffix. 

But this is a somewhat time-consuming extra step that should not be necessary.

Then bring that step model into the Solidworks project.

Export to STEP with suffix does not add suffix to extruded parts, casing problems in SolidWorks - Altium Discussion Forums

Thank you per !

Another workaround would be to date/time stamp the board using special strings.

Example of using a Current date stamp

=PCB_PN+' '+CurrentDate

Example of using a Current date / time stamp

=PCB_PN+' '+CurrentDate +' '+CurrentTime

That's it !
