Resolving YELLOW X via Keyboard command?

From another post I have determioned that I have an unrouted connection

Background:

I have a small SMD electret microphone (3mm dia) who pads form 2

concentric circles (like a target bullseye). The center pad must

include a via to the bottom layer (of a 2 sided board) for routing.

I can not seem to finish this manual route through selecting via

mouse... how do I route this and get rid of the YELLOW X ?

Good morning, Chuck

If you ripup the trace on the bottom side of the board, you'll be left

with an air wire from the center pad to the next trace segment.  Start

routing the air wire from the end of the trace on the bottom to the

center of the pad, then change layers to the top, and route some

distance away.  This will leave a via in the center of the pad.  All

that's left is to ripup the last segment on top.

Is there a keyboard command that I can execute on the route?

Sure.  See help via.  The command will be something like

    via 'signal name' (x y);

where x and y are the coordinates of the center of the pad, and "signal

name" is the name of the net to which the pad and via should connect.

Optionally, you can leave the x and y coordinates off and click on the

center of the pad:

    via 'signal name'

then click on the center of the pad.

HTH,

Awesome. Thanks for the detail Chuck, I'll give it a try.

The cross is likely being caused by no routing between the top of the via

and the centre pad.

The quickest remedy is:

(1) Drag the via away from the mic. pad. You should see the air-wire

attached to the mic. and via. (Remember the via must have the same name as

the trace).

(2) Run a top route from mic. to via

(3) Move the via back under the mic.

Edit: #4 may be the keyboard command you are looking for

Adding to what warren said, the yellow x you see is where two same-net traces of different layers align endpoint to endpoint or endpoint to center.  You can get rid of this x by placing a via precisely at the center of the X.  However in order to do this, the X must be centered per your board grid.

1) set your routing grid

     example: routing grid of 2 mils

     type the "" enclosed text below followed by enter

     "grid mil 2"

2) Using the move tool press (left-mouse + ctrl) to select the endpoints of the traces,  By using CTRL the endpoint is pulled to the nearest grid point.

3) Move the endpoints to where they are aligned center to center, and hit ratsnest.  You should see the yellow x appear at the new pseudo connection you made.

4) either use route (left-mouse + shift) or the via tool itself to connect the traces.

5) Hit ratsnest again.  If all is well the yellow x should go away.  Also take a look at the bottom of the eagle window after hitting ratsnest.  If all connections have been made you should see the message Ratsnest: Nothing to do!
