I did this and it works for all new files:
Mapping Model Custom Properties ($PRPSHEET Annotations) to Drawing File Cards in the EPDM help files
This works when creating a new drawing from a part or assembly file but what about for files I am importing into the vault for the first time for a legacy file? All my data cards for the drawings are empty because they were created prior to Enterprise PDM. What can I do for all these files to prevent manually updating all the drawing data cards. Shouldn't there be a way when importing into the vault the first time to automatically link the properties to the model's properties?
