Question:

When opening a design file in Microstation alone, temporary survey graphics that have been previously displayed remain in the file.

or

When opening a design file with InRoads and MicroStation, graphics are visible until a MicroStation command is run, then the graphics disappear. 

Answer (for InRoads running in MicroStation):

When displaying temporary survey graphics in a design file using the command Survey > View Survey Data, it is important to recognize that these graphics are actually written to the design file as graphic elements.  What makes these graphics “temporary” is that they are marked with an XAttribute which only makes them visible when the fwd containing the data is loaded in InRoads.

To resolve this issue, Bentley has developed a utility that will delete temporary graphics from MicroStation design files.  With this utility, the user has the option to completely delete the survey graphics or strip the graphics of their element attributes.

The Delete Survey Graphics Utility can be downloaded HERE.

Once installed, the utility can be accessed from the Windows Start Menu - Start > All Programs > Bentley > Delete Survey Graphics.

At Directory (within the Delete Survey Graphics dialog box) navigate to the folder that contains the design files with survey graphics to be deleted or stripped and Apply.  All files in the folder selected will be processed.

Answer (for Power InRoads):

Download and install the Delete Survey Graphics Utility located HERE.

Once installed, launch Power InRoads and go to Utilities>MDL Applications and browse to the "DeleteSurveyGraphicsAT.ma" file in the "C:\Program Files (x86)\Bentley\Delete Survey Graphics" folder.

This will run the Delete Survey Graphics command inside Power InRoads, allowing the user to define a folder which contains the design files to repair.
