Hi JTB,

That shouldn't be necessary - you can just export solids or surfaces from MoI into SAT format and then inside of Revit use Insert / Import CAD to bring in the SAT file.

But I don't think that you can bring in curve data this way, only surface or solid data. I don't know how you bring in curves from a different file format, there seems to be an Insert from File / Insert 2D Elements from file command, but it only seems to be able to open Revit file format.


> How can I make it a Revit mass?

I think maybe the way you do it is to first create a new mass (I guess "Massing & Site" and then "In-Place Mass") and then while you are still in that mass creation mode, at that point go to Insert / Import CAD and bring in the SAT file, that seems to make it part of the mass. Then hit Finish Mass and it seems to be set up I guess? I'm not very familiar with Revit so I'm not totally sure, but that appears to work.

Something like this:
