Simple question about editing pads

And though I have accidentally modified the traces plenty of times, I have no way to modify the pads in the center.

 

So my question is- how can I edit, and more specifically, redimension and move already existing pads in a board file?

 

Moving and editing pads that are just pads, placed on the board as just

pads, is easy. But that's not what you have. You have a board with two

SOIC-like devices placed on it. They're probably ICs that exist as such

in the schematic. This is, of course, the RIGHT way to do it, and it's

your question that's fundamentally wrong.

I'll assume, for the sake of an example, that what you have are buffer

ICs that are available in SOIC, but that you now want to fit the TSSOP

versions. You're looking at this as "so I need smaller pads, closer

together". That's WRONG. What you need is... TSSOP packages. So the way

you do this, and it's really obvious once you know, is to "CHANGE

PACKAGE" the ICs. Either enter that on the command line or click the

spanner icon and select PACKAGE from the menu. Then click on the little

origin cross in the middle of the IC. You will be offered all the

available packages for that device. Select TSSOP.

Your parts (devices) in the centre are BLK-MD-SPK-B with a package of

the same name in a library (same name). (I don't know what is is

supposed to be)

Devices one cannot  change in schematic or board. They must be edited in

the library, or one must create a new device that fits the suits.

Also a package has a body and a name/value. just check a package in an

eagle library to see what is necessary to make a correct device.
