When calibrating an Optiv 321-gl the "Calibrate Optics" part...
after the pixel size part runs on the concentric rectangles it goes to check the "Rotation and 2d lens distortion>>> (which automatically turns on the Camera Rotation part)
... the cmm moves above these rectangles to find the line for camera rotation...
This line on the B&S Glass calibration standard is actually located beneath these rectangles
thus it can not find the line and it can not finish the camera calibration.
This routine Calibrates fine in 2017 32 bit, but not 2020 R1 in 64 bit... anyone else experience this???
