I am a complete newbie to Eagle. I am designing my first schematic and PCB layout, and while I've read many tutorials and found them helpful, I'm running up against two questions I can't answer because I don't know the right terms to search for! I keep coming up empty. Here are my questions:
1) What is this dotted red line that is hiding under my trace, and why can I not delete it or move it? It exists in the Top layer. It appeared after I used the autorouter and then added a pad/trace in the schematic later. All I want to do is delete the dotted red line. Even when I group all and rip up all the traces, it stays.
2) I've draw lines to change the board dimensions, and they exist in the dimension layer, but there are blue lines on the outside which I cannot move or delete. They exist in the bottom layer. Here I am displaying only the bottom and dimension layers. The white line shows the dimension I want. The outside blue lines are what I want to change.
Thank you so much in advance for your help. Even if you can just give me links or the right search terms, that would be amazing.
