This username variable is saved per computer, not per user. So if you have multiple people using a shared computer, the username needs to be manually changed each time Revit is used for a central file project.
However, you can create a desktop shortcut for Revit 2011 and add the startup switch /username. This will set the username to your username whenever you open Revit 2011 with this shortcut.
- Make a copy your Revit 2011 desktop shortcut
- The name of your Revit 2011 folder will vary depending on how it was installed
You can create one of these custom shortcuts for each user of a shared workstation. In my case, I use it on a remote computer in another office that a few of my co-workers also use.
Note: If you do not get the Target box when you right click over your new shortcut, you will need to create a shortcut from scratch. Open the folder on your computer that contains the Revit.exe file, right click over Revit.exe and select Create Shortcut. Move the new shortcut to your desktop.
