Currently, when exporting a Revit model to .RVZ file, the Revit "Mark" (Identity Data.Mark) parameter only gets exported for certain Revit family types, such as a door family. Generic Model families, however, does not export the "mark" parameter and therefore is not part of the translation to another source, which in our case, ESRI Shape Files.
Being able to export the Mark parameter for all Revit types would be extremely helpful, especially here at the Denver International Airport where we work with big data.
