Using an Environment Variable so when attaching a raster image it will not matter if a different share drive letter is used when the DGN file with a raster image attached is opened by another user. 

Background

When attaching a raster image an Environment Variable will be used as the folder path, which will show the UNC path instead of the folder path.

Steps to Accomplish

1.)  Define Environment Variable in Workspace > Configuration

• Variable Name: “Variable Name to be used”
  
       (Ex: RASTEST1)
• Variable Path: “Machine path to be used”
  
      (Ex: \\”Machine_Name”\test\)

2.)  Raster Manager > File > Attach

3.)  Attach Raster Reference

• On the top right next to the Bentley “B” you will see a folder with a star in the middle
• Click the folder with the star in it
• Select Configuration Variable
• Select the Environment Variable that was defined from the list

 4.)   Select raster image 

• In raster manager right click on the raster image name and the Environment Variable path name and the raster image name will display.
• Define the Configuration Variable name on all workstations.

If MicroStation and Descartes are used or if custom userspaces are used then the Environment Variable must be defined in both MicroStation and Descartes and all custom userspaces that are used. The Environment Variable will only be valid in the userspaces that the Environment Variable was defined.
