Display Problems - Stray Lines or No Lines in DGN

Product(s):InRoads, MX, GEOPAK, MicroStation
Area: Basic Settings



If you experience problems with your graphics display, it is most likely caused by your computer hardware graphics card.  See example screenshot below If you have Unstructured, Stray or NO lines are displayed.

In this case, the issue was caused by the NVIDIA Graphics Card Driver.


  1. Go to your Graphics Card manufacturer’s support webpage, download and install the latest version of Driver Software for your particular graphics card. Close down your Bentley produce and start it again.
    Did this solve the problem? If not or if the latest version was already installed, continue to Step 2.

  2. Change the computer Environment Variable to force MicroStation to use DirectX version 9 instead of DirectX 11 or 12.

    1. Go to Control Panel\All Control Panel Items\System\Advanced System Settings.

    2. Click on Environment Variables.

    3. Under System Variables click on New.

    4. Create a New System Variable

      For V8i:
      Variable name:                  QV_D3DVERSION
      Variable value:                  9
      Click OK

      For the CONNECT Edition:
      Variable name:                  QV_DISABLE_D3D11
      Variable value:                  1
      Click OK

    5. Back in the Environment Variables dialog, click OK

    6. Back in the System Properties dialog, click Apply then OK.

    7. Restart your Bentley product. The issue should now be resolved.
