Good morning
I'm an Architect in the phase of ךקשרמןמע moving for CAD to BIM - AutoCAD2019 to REVIT.
In my CAD projects i use a spot elevation mark that indicates the level of the floor and th hight of the floor - net from flooring to the UK of the floor above. it is an important information in the design phase
I'm looking for a way to define a tag that includes a parameter that takes that data from the REVIT model.
Tx for throwing your ideas at me 
Eric
