Simple question about editing pads

Question

I've been trying to edit the spacing/position of the pads on this example .brd file-

http://www.instructables.com/files/orig/FG0/FRGD/I4PHX5J0/FG0FRGDI4PHX5J0.brd

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?

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.

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.
