I am trying to set a global property mapping rule so I can get the revit family type identified in takeoff description. I added a takeoff property "Description 1" Category "Element" and Property "Type" and selected ok. I am unable to figure out how to get this new column added to the Choose Details Columns. I have a column for Description, but my new mapped Description 1 takeoff property is not a column option to be shown? Please advise how I get the Description 1 column into the takeoff details.
