    Civil 3D: Grading Optimization Problem

    Do you have an issue displaying the Grading Optimization (GO) window with Civil 3D 2022.1 and GO 2022.2?  If so, read on.

    I have been working with GO since it arrived, but when I installed the Civil 3D 2022.1 and GO 2022.2 updates, GO failed to display once I click “Optimize”.  The windows actually appear, but only the shadow edge.

     

     

    Autodesk is working on a public fix, but they asked me to try this, and it worked.  Create a new Windows Environment variable with this name and value.

    Variable:              USE_ANGLE

    Value:                  d3d11
