How to fix the REDSDK error?

Symptoms

During operations suddenly an error dialog appears mentioning a REDSDK error.

Cause

  1. The REDSDK display device is used for rendering as well as drawing with a range of visual styles. For instance, it is used for Realistic visual style, but not for 2dWireframe.

    This suggests a possible bug, for which we recommend submitting a Support Request.

  2. Roughly we can distinguish between cases where the error can occur over a wide range of graphics drivers, and cases where the error is specific to a specific driver of a specific card.

    It may be that the graphics card is not supported very well, or just that the driver of the card is outdated.

Solution

Generally, it is a good approach to start with an update of the graphics driver. This resolves a lot of cases. If that does not work, please file a Support Request and list the actual error as well as the output of the BricsCAD command REDSDKINFO.

Note:
  • Hidden, Gouraud and Flat visual styles may be drawn using REDSDK or OpenGL depending on GSDEVICETYPE3D system variable.
  • How to avoid using RedSDK when there is a problem (as a temporary workaround):
    • GSDEVICETYPE2D system variable can be set to anything but 2 (RedOpenGL). By default, the variable is set to 0. It is then safe to use visual style 2dwireframe.
    • Set GSDEVICETYPE3D system variable to 0. This allows using visual styles HIDDEN, FLAT, GOURAUD because these styles then do not use RedSDK.
    • Don't use RENDER.
