Bluebeam’s Revu is a popular Windows OS PDF markup and editing software amongst architecture, construction, and engineering firms. To have the full functionality of the software’s file-locking capability with LucidLink, the following 2 configuration changes must be made in the LucidLink Control Panel: 

1. The mount point of the LucidLink Filespace on each user’s Windows machine using Bluebeam Revu must be a UNC path. ( i.e. \\lucidlink\filespace ). 
   1. Failure to do so will not produce a popup window in Bluebeam Revu notifying a user that another user has that same file open. Only when the user tries to save changes to the file will they be notified that the file is read-only.
   2. Note: One can mount the LucidLink Filespace as a UNC path and a Windows drive letter simultaneously ( i.e. \\lucidlink\filespace;L: )
2. The file extension pdf must be entered into the File Locking Extensions list. This is done under Global Defaults in the LucidLink Control Panel while logged into the Filespace as a LucidLink administrator.
   1. Failure to make this change will result in no locking occurring amongst users opening the same pdf file, resulting in users potentially overwriting other users’ work on the same pdf file (the last write wins). 

First, let’s set the LucidLink mount point as a UNC path and make it the default for all user’s of the Filespace. To do this, login as a LucidLink administrator and go to Global defaults in the Control Panel. Under the Mount point (Windows) section, enter \\lucidlink\filespace;L: where lucidlink, filespace and the drive letter can be whatever you require. Then, click the checkbox to save your changes. 

After making the change to Global defaults as an administrator, each user will need to reconnect to the Filespace (logout and log back in) if they’re currently logged in to get the new default mount point. 

Next, the file extension pdf must be entered into the File locking extensions list under Global Defaults while logged into the Filespace as a LucidLink administrator. After doing so, click the check mark to save the change.
