[sdiy] Building parts in Eagle - continued

[Julian]

Firstly, thanks for evreyones initial comments.

On the strength of them, i have begun.

The tutorial i was working from suggested coppying and then modifying existing parts.  I couldnt work out how to do that, so i 
started from scratch.

I now have my component (a slide switch) and have made the package, the symbol, and have then made the device.  All thats fine.

Ive now been messing with it in a schematic and board file.


However, now i want to go and alter some things in the package.  Notably, i want to increase the pad sizes.

If i try and edit the package, i get the "package is in use" error.  I assumed this ment it was in the scematic and board file, so i 
coppied and renamed the whole lib. file, and im still getting the error.


So, what im wondering is -

How do i get to edit this package now?
And, when i can, i didnt initially see any way to increase the pad size.
And... how do i copy 'devices' between libaries?

Another minior irritation is that i seem to have ended up with different names for the symbol, package, and device.  Ideally i would 
like to name them all the same, but now cant find a way to rename them : (


...but, yeah, appart from these irritations, simpler than i thought it was going to be.  So far at least : )

Thanks again,
Julian
