Hello,
I am using Allegro 16.6 and have finished a PCB but after checking it over I am a little confused as to why some vias on the GND net show a cross over them (I guess this indicates they're connected to the GND plane?) but others do not. The crosses seem to be affected by the views drop down menu in the visibilty window. I also see that the power planes on power layers don't show any clearance around vias that aren't on the net of the plane, but all other shapes have some clearance around the vias. Is this normal? I don't have any indication that there are unconnected nets or shorts, but I cannot figure this out. What exactly does it mean if there is a cross? Is it possible for the via to be connected if it doesn't show the cross? I want to be sure everything is in order before exporting gerbers to the board house. Thanks
