Bentley Raceway and Cable Management (BRCM) reads and writes both MicroStation DGN file format and the AutoCAD DWG or DXF file formats. In cases where DWG files are opened in the application some tools like Clip volume and Clip mask are greyed out and a message “ This action is prevented by a capability variable” is displayed in the Message Centre.There are two WorkModes available in Bentley Raceway and Cable Management- 1. DGN WorkMode-Full MicroStation capability is enabled. 2.DWG WorkMode-Certain functionalities are disabled by default in order to restrict the application to create only the information that can be stored in DWG format. The WorkModes are specified by the value of the configuration variable MS_WORKMODE. By default the value for MS_WORKMODE is set to DGN.
1.After opening the DWG file, Go to File and select Settings and click on Configuration. Select Configuration Variables from the configuration settings. 2.In the Configuration Variables dialog, search for variable MS_WORKMODE which is set to DGN by default. 3.If DWG file is opened MS_WORKMODE value need to be set to DWG. Click on Edit and set the value of MS_WORKMODE according to the file opened. Note- While working with DWG files certain MicroStation functionalities are disabled so that the file will be compatible with the DWG format.
