Add a property from the drawing
Operation possible on parts or assemblies. 
This operation creates a property on the 3D document (part or assembly) based on a property from the drawing. If the property already exists, it will be modified.
Example:
Create the " Revision" property in the part or assembly by retrieving the " Revision" property from the drawing.
For this operation, you must specify, in the options, the folder(s) where the drawing files can be found.
