Sorry if this question was asked. I created a symmetrical room, I make my first drawing (of my parent room) then my second drawing (of my child room). My question being on this point, I would like to create an automatic block that would indicate the name of the parent part file on the plan of my child part to avoid redoing a new dimension that would make no point.
If I understand correctly, you want to retrieve the name of the parent part so that in the workshop, when looking at the child part, they refer to the parent part but in symmetry.
In my image, the parent piece is called the 500x500 sym couverrtine and the child and its symmetry.
In the concept your method works but what I am looking for or rather avoids doing these manipulations to add the view of the parent part (waste of time to mark the parent reference in annotation). So I would like to create a block that would indicate the filename of the parent part (for tracking in the workshop as you specified in your last comment).
