Not sure if this is a bug, but it seems that settings in the View/Nets menu are overriding the CAM settings?
If you set a net to a color (other than black) in the View Nets area, then want to do an assembly dwg in CAM set up
and have ALL pads set to light grey, the output of that CAM to PDF displays & prints those pads set to that other color in View Nets.
This does not seem like it should be an intended action??
