HEY! I need create walls inside my mass but I cant reach them and I got autocad file but when I want to export only few things it explore all the mass and I cant just massing first floor or other details. Outside ornomenths and walls I can create wall by mass but inside cant! Please help with advice. Autocad and revit file in attachment.

I know you've posted several times about this over the past week or so. I'm not really understanding what you are struggling with. I just inspected your CAD and most of it (not all of it) will import into a Revit In-Place Mass session. When you close out of the In-Place Mass Session (after importing the CAD into it), Revit creates a Mass Form from it.  Now it's just a matter of isolating, in the view, the CAD layers that the Walls are on and then using the Wall by Face tool to apply walls to the interior and exterior Mass faces that were created from the CAD Import. I just tested. I isolated in the view the CAD Import Layer named  "2.stavs-sienas" and applied walls to the exterior faces.  I had some issues which I had deal with, but the process works pretty smoothly for the most part.   Still, there is going to be a lot of work that needs to be done "manually".

You would be better off modeling this from the beginning in Revit.
