I am trying to re-route my board, so I changed the board size using the "board planning mode". Now, I'm routing, and some tracks are "blocked" by something looking very much like the old board limit. Is there a workaround or I failed somewhere??

PCB Routing blocked

Another question linked to that, at the end of the "auto routing", it tells me there is 1 or 2 connection failed to complete, but I see none. How to find them?

  • \$\begingroup\$ Typically, keep-out areas are in pink. Are you sure you don't have keep outs where you want to route ? What does the 3D view show (key 3) ? To find unrouted tracks you can do a Design Rules Check in Tools, and look for Net antennaes. \$\endgroup\$ May 17, 2022 at 14:28

I think you are routing on the wrong layer, you should be running traces on red or blue (usually top or bottom) copper layers. Purple is usually a mechanical layer.

  • \$\begingroup\$ Purple is the colour I gave to these specific connections, it's shown at bottom left, I'm on the top layer \$\endgroup\$
