I was trying to create a relation that would simply see if PTC_MODIFIED:D for the drawing was YES and then add a + sign to the rev on the drawing title block. However:
1 - Regular relation functionality does not exist for a drawing file, only the model
2 - Relations in repeat regions only use localized parameters, not the model parameters.
PDMREV will show the +, but it will also show the iteration, which I don't want to put on the drawing.
Either or both of these being available in future releases would be great!
