Problem
Floor Manager is empty when i try to create a new floor and I am getting the below error message “Failed to check out BB_FloorMaster.dgnlib” when clicking on Grid Systems Manager:
Solution
The primary reason for this is that the two files BB_FloorMaster.dgnlib and Project_Materials.dgnlib were not present in your \Standards\DgnLib folder of your custom workset or somehow removed from the delivered workset. The steps below should help to resolve this issues.
For example, the location of the above variable for the Bentley delivered NM dataset is
[C:\ProgramData\Bentley\OpenBuildings CONNECT Edition\Configuration\WorkSpaces\Building_Examples\worksets\BuildingTemplate_NM\Standards\DgnLib]
Note that the workset from which these files are copied should use the same working units as your workset.
