Something funny happening here, I think something similar has been reported before. After doing a new schematic design and then translating to PCB, a lot of net connections are not showing. Go to the net list and you see some of the nets are marked to be NOT shown !!!. Why is this happening ? ... Also to undo this you need to double click every NO to change to YES .... very laborious when there is a lot of them, can this not be changed to allow you to change the whole column to Yes ?.
Further to this in the spacings dialogue before V15 you could "apply to row" but you cannot do this now !!
I get this all the time - it's extremely irritating and for some reason not always picked up using 'net completion' reports. The global show nets tick box doesn't work correctly - it should cycle between clear (all off), grey (some showing) and ticked (all on) but doesn't seem to reset the individual show connections correctly when it is ticked.
