Hello everyone!

I have a general question. I am working on a LOD 200 small retail chain that wants their shelving racks to be modeled and sized. I am using generic parametric families with WIDTH, LENGTH and HEIGHT as the fields. I want to create a tag that would read these length parameters but have had no success. Is there a way to create this? I am in Revit 2019 and willing to change the type to specialty equipment or something like that in order to get this tag to work properly as I have several locations that are needing this information.

Thank you in advanced!
