Yes,
I've been a design engineer for 25 years now and one thing that is critical are Datum planes. All features should be located relative to a datum structure. It would be very helpful if a construction plane could be designated as a Datum plane with a tag attached to it and have it showing on the screen. I'm at a loss why this isn't already standard operating procedure. These datums plane could then just be shown on a drawing instead of having to create them manually. Datum Targets for castings, forgings etc., would also be really helpful.
