* This is not a problem with the PCB Editor or the Autorouter. The problem is that somehow you have got a set of nets with duplicate names. See red highlighted nets in the screenshot below: ![enter image description here][1] You can see these by checking using the Design Manager (left panel). You can also see them in the unplaced/unrouted PCB by using the Design Manager: ![enter image description here][2] * To fix this, delete the nets with duplicate names and redraw them. To help avoid issues like this, please follow the guidelines and checklists described in: https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f [1]: /editor/20180114/5a5a4c9bea683.png [2]: /editor/20180114/5a5a4dc32ea7f.png

Hello, i can not fix the problem. when i delete all connections net A and C also exists. New connections allways bind to net A or C. Please help me. Best regards Toni

I do not know why but there was a problem with the pin definition of the `zener diode` schematic symbol in the library. This has now been fixed. Delete the symbols in your schematic and then replace them with the same symbol chosen from the system library and your `A` and `C` nets will go away. :) :)

Thanks is work very well :)
