Move wire from bottom to top layer

Community PCB Design

I have a question about Eagle Cad. I used the Auto router function and for some reason Eagle placed a route (wire?) on the bottom layer while it isn’t a problem to have it on the top layer.

I could delete the route on the bottom and make a new one on the top layer, but Eagle Cad says that it ’ Can not back annotate’ it and I should do this on the schematic.

Is there a way to move a route on the bottom layer to the top layer automatically?

Thanks in advance!

In eagle you can’t “delete” routed wires because eagle sees them as an interconnection between two points. What you want to do is unroute the wires using the “ripup” tool (it is next to the route button).

If you want eagle to autoroute on the top only, in the autorouter setup window change the “cost” of routing on the top to a higher number. The particular value you’ll want to change is in the “layer” tab of the autorouter, and is in the “layer costs” section.

Hi,

Thanks, I used the ripup command and it after that I was able to do what I wanted.

Thanks again!

Greetings JanDirks,

I think you have a working answer, but for future reference

you should know that any routed trace on any layer (by

hand or auto-routed) can be changed to different layer

with the ‘Change’ command.

1 click the change icon (a wrench)

2 select layer

3 select the desired target layer

4 select the trace sement you want to change with

the L-mouse button.

EAGLE will make the change and add a via as needed to

connect back to the original layer. On long traces you

can continue to click segments until all the desired layer

changes are in place.

Another method is to type commands, so the above

sequence would start with typing “change layer”

and selecting the desired target layer as before.

There’s a lot of EAGLE horsepower that most of us

don’t know.
