I have been trying to learn how to detail in Revit with Fabrication CadMep. I am switching from AutoCad. It seems that the Fabrication objects can only be tagged with Fabrication tags (in Revit). There is a bottom of duct elevation tag. There is a top of elevation tag. But there is no top and bottom elevation tag. Combined top and bottom tags are the industry standard. How do I get a top and bottom duct elevation tag? I have learned how to combined Revit mep tags, but Fabrication tags seem to be separate from mep. Thank You
