Hey there.
If i copy/paste a via for example the pasted via don't have any net defined.
Now i want create a panel of x counts of the made pcb, all the copied pcbs get DRC errors.
All copied PCBs don't have any net signal names included, so all polygons with vias will be destroit now.
Hope altium will fix that too in the next versions...
Greetings, Bjoern
