I was just at the subscription center to ownload the latest build and found this in the download page:
Download Autodesk Revit Building 8.1
Download Revit Building 8.1 for AutoCAD Revit Series
First one I know but the second I have no clue what it is and cannot find anything on the autodesk website.
What is Revit Building 8.1 for AutoCAD Revit Series? Anyone know?
