If you have an explicitly mapped attribute, and you populate that attribute in a drawing from within Windchill, should not this attribute populate in the mapped parameter of the CAD model once that CAD model is opened in a Creo session? Shouldn't the client-side workspace automatically synchronize the metadata? The example follows.
Attribute Name = My Box
Attribute internal Name = MyBox
Creo Field Mapped Name = CARTON
Creo Drawing Parameter = CARTON (designated)
Creo Model Parameter = CARTON (designated)
Operation
Perform Check Out and Edit Attributes on drawing in Windchill (MyBox = Standard)
Check In drawing
Open associated model (,prt) in Creo
Should not CARTON = Standard?
