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
