Please advice. What is the difference when check marking GROUND PLANE PREDICTION? I don't see it. I have done Prediction with and without it,

the prediction looks the same.

I have the same question. This images show a pair of 2 stacked 1100 LFC's, one with ground plane activated and the other without it, I realy can't tell the difference.

Update: I found in the HELP page this:

Hi Bruce, you should activate only 1 geometry as "Ground Plane" in the Object Settings tab, also in Menu>Edit> Ground Plane Prediction as you mention, you should actually see the difference in the model view after Predict and see the difference in Measurement View
