Changing signal names to pads on board

i think you need to connect them in schematic to get the airwires first,

then route them on the board. but i must admit, i don't fully understand

your post.

Gary,

In the required process to replicate both a circuit to the schematic and

  its matching board layout, only one file is open at a time.  After all

copies are made, both files are kept open and the process of "cleaning

up" the inconsistencies begins.  In this case, as EAGLE does its

renaming thing, it has disconnected the signal from the pad.

While I cannot get an airwire to connect to the pad (and this rename the

signal to match the schematic, the "SHOW" command does highlight it...

At present, adding a part to the schematic does not add the part to the

board if I remember correctly, but will try that again.  If so, that may

only be true as long as the inconsistencies exist.

maybe you can disconnect the offending pad in the schematic and then

reconnect it to cause eagle to forward annotate to board, then you can

route the new airwire?

and yeah, i once got a schematic and board out of sync, not fun. can be

a true nightmare.

Gary,

Turns out the solution was pretty simple.

1. Add a wire (not route) on the appropriate layer near the pad needing

an air wire connection to it.

2. Rename the wire to the pad name, and an air wire is made.

This technique also worked well to force an air wire to the center of a

pad to thus provide for a clean routed trace: If the air wire is not on

the pad center, add a wire, rename, and the rip it up.  An air wire is

left behind, ready for the final routing operation.

Also proved having additional parts placed on the schematic will again

automatically appear in the board- once both are again consistent.

You can start routing at any point on a existing track by holding down CTRL

while cliking there.

Olin,

Thanks for the tip!
