Bentley’s MicroStation is a popular Windows OS CAD software used in infrastructure projects that has been in use for over 20 years. In order to have the functionality of the software’s file-locking capability with LucidLink, the following configuration change must be made at a command prompt.

The MicroStation file extension dgn must be entered into the File locking extensions list while logged into the filespace as a LucidLink administrator. After doing so, click the check mark to save the change.

Failure to make this change will result in no locking to occur amongst users opening the same dgn file, resulting in the potential of users overwriting other users’ work on the same dgn file (last write wins). 

Note: If using MicroStation to edit AutoCAD files (dwg extension), this file extension is already entered as a file-locking extension by default. Making this change will also allow successful locking of dgn files by other applications such as AutoCAD. 

You will need to capture the current list of locking extensions configured. To do this, type the following at a command prompt:

lucid --instance 2001 config --no-trim

This will produce output listing the EFFECTIVE and CONFIGURED options for each configurable option. Copy the CONFIGURED list of file extensions for FileSystem.LockingExtensions.

Then, type the following at a command prompt copy pasting the extensions list you just copied and adding ,dgn to the end of the list:

lucid --instance 2001 config --set --global --FileSystem.LockingExtensions indd,idlk,dbl,dwl,dwl2,dwt,dwg,ppt,pptx,xls,xlsx,doc,docx,rvt,revit:dat,dgn

Press the ENTER key. You will be prompted to enter the password of the LucidLink administrator you signed in as.

Changes will be effective immediately across all uses without a need to reconnect to the filespace.
