Homebrew PCBs

I'm trying to create pads for a simple SPST NO switch.   After typing
PAD 0.06,
a dialog box pops up saying

"The Pad command can only be used in a package!"

What else must I do to place pads (filled circles or ovals) on my
schematic?   
Thanks.

I don't use Eagle, but pads only make sense in a PCB design or a PCB 
footprint.

  Look in the testpad library..

  A couple of other suggestions..

  Make a 'mydevices' library, and copy your most commonly used 
components into it.

  Once you have that going, go through every library.  Leave the ones 
that are obvious like 74TTL etc alone, but look at every component in 
most of the other libraries.  Copy the good components out of the 
libraries that only have a few components that you'd ever use.  Then get 
all the libraries you no longer need into a backup folder etc.  
Streamline everything into what you'll actually tend to use and things 
become a lot easier..

Or In the board you could just use the circle command on layer pad and
drag out a circle using the width adjustment at the top to get a pad
size with a id that is appropriate to the correct pad size you are
looking for then use the copy command to place it on all of the pads
you need to make bigger

That sounds like a good idea, Alan.  I did copy the library to
mylibrary.   When I figure out how to delete parts from a library and
copy and paste parts from one library to another, I will build my own
custom library as you suggested.

Right now, I'm taking baby steps with Eagle, staggering like
Frankenstein's monster on the loose.    Falling down on every second
or third step.

I tried your suggestion, Wag.   But I tried to make a completely
filled pad, and I don't know how to fill a circle, or if it's even
possible.    On the other hand, I guess it wouldn't hurt to use an
unfilled circle if I made the circle rather thick,  since I will be
putting switch leads into the middle of the circles.     Anyway, I did
change the color of layer 91 after reading your suggestionsâ€"just to be
sure my circles and wires were actually going into the copper on the
trace side of the board.   Thanks for the suggestions.

In Eagle, in a Device (the item you select from the library while
adding a component to the schematic), is composed of a Symbol, which
is what appears on the schematic, and a Package, which is what appears
on the board.  In order to remove a "component" from the library, you
must first open the library it is in, and then select Library/Remove,
and a dialog box will pop up asking you to type in the name of the
file or object you wish to remove.  First, you remove the Device,
which would be something like 2N2299.dev.  Then, if you wanted to, and
if the symbol and package are not used by any other devices, you can
remove them as well.  Eagle will not let you remove a device if it is
in use, by the way.

You may find this link useful.  Like you, I started from scratch.  I
copied and printed out the "Library Technique", "Schematic Making
Technique" and "Board Making Technique".  Maring new parts is covered
in sections of the "Library Making Technique" stuff.  Here's the link:
