When exporting a Revit Architecture model using IFC 2x2 to AutoCAD MEP, the parameters come across pretty well, with a minor hiccup. Revit parameters can includes spaces - but ACAD MEP property set definitions can't read an item with spaces, so with every update, you need to open the newly exported file in ACAD MEP. Rename the Pset_Revit_Identity Data property set definition to Pset_Revit_IdentityData . Next, you can edit the ACAD Arch block definition used in the mvblock definition's default room tag's name and number attibutes to read this new property set instead of "spaceobjects".
Try it out - I've got a the block edited in a new Schedule Table style drawing if wanted - it's small enough to email, so send an email if you're interested.
