I have written briefly about advantages to the Autodesk eTransmit for Revit, the 2018 version made a small but significant improvement. While talking to the Revit Colaboration Team and upgrading a project Kyle had pointed me to this post about upgrading a Project Hub. The document had a hidden gem in it about the eTransmit tool. In the 2018 version they added the button “Browse folders …”, previously we could only browse for a single .rvt file. This button allows a user to upgrade an entire folder. The files will still have to be opened after the etransmit, such that they can become central models once again. But the time saved not having to wait for each file to finish only to open another is eliminated.
