For a workflow process to enhance collaboration with Revit, i would propose to enhanced export capability’s to export from factory design utility's to a RVT file with the sub assembly’s in the lay-out as RFA documents. allocated with the right category and connections so that the engineer working with Revit can use these connections and categories. an assembly can already be exported to RFA with this functionality, and the factory lay-out should be able to place these in a RVT file.
Now it makes a simplified document and loses all the category detail and connections.
You can also already get the MEP data from different assembly’s to the factory lay-out to use these but it is not possible to get these in the RVT file.
