Im trying to understand the basic functions of "eagle" PCB creation
software. Before I buy the full version I want to see what it can / will do.


Unf I can't find the v basic pieces in the libraries - single resistor?
electrolytic cap? simple diode?

why is it all buried so deeply?

You will find resistors, capacitors and inductors in the RCL.lbr library.

ok. So once I've "opened" that library - do I click "add' to get the part to
drop in? I didn't see it listed there - just lots of esoteric bits.

First, make sure that the RCL library is selected for use. You can do that from
the Eagle Control Panel by expanding the Libraries folder and making sure that
there is a Green Dot beside the RCL.lbr entry. If not, "Right Click" on RCL.lbr
and select "Use". Only libraries that are selected for use, are available to
add components from.

Then in your schematic click "Add" (AND Gate w/ Cursor in Eagle toolbar), expand
the RCL library and select the resistor package you plan to use. You can change
the package later if you need to by using the "Change Package" command (see
Eagle Help).

If you haven't done so already, spend a few minutes going through the Eagle
Tutorial. I think you will find that it saves you lots of time in the end.

There is a tutorial you can get from Cadsoft's website that I recommend you
should read through and follow. After that you will have no trouble using
the program and libraries. Regards,

Can someone explain the diff between

wire
net
bus

in Eagle?

Please don't top-post.

I have used Wire on board layouts to fatten up things (a cheat)
or to draw a line in the copper not meant to be conductive.
(Wire really should have been called Line.)
It is best to avoid the Wire command completely.

Use Net for most paths.
Use Bus for things like a multi-bit address bus (A0, A1,...A7).

Outside of Cadsoft (you have read THEIR manual, haven't you?),
Kevin Bolding does the best EAGLE tutorials.

Jeff Hudson did a nice one,
but it disappeared shortly after I bookmarked it years ago.

Why not just "change width"

Yes. It was a kludge.
I don't remember if it was in the days before I'd learned all the tricks
or if I was just in a hurry to etch a one-off.
It seems to me it had something to do with limited space in one direction.

The bottom line is:
avoid using Wire for conductors; the command is poorly named.

What you just did. Never quote the whole message you are replying to.
Never place the answer before the question; you are not playing
"Jeopardy(tm)". Quote just enough of the message to establish the
context of your reply, and then put your reply right after each point
you are replying to. Elementary newsgroup etiquette.

Here is your latest "post".
http://groups.google.com/groups?&selm=_tZ8d.423885%248_6.386675%40attbi_s04
It comtains stuff that does not relate to the question at hand.

At the beginning of this post (mine)
is an example of what should have been posted (4 lines of text).
Notice that I have re-arranged the comments so that
the 1st comment chronologically is physically above the subsequent
comment.
It reads top to bottom like a conversation.
As David pointed out, it's about courtesy within the Usenet community.

An example of why not to top-post:
A. Because it breaks the logical sequence of discussion
Q. Why is top posting bad?

Here is what the original document on which Usenet is based
(Request For Comments #1855) has to say about top-posting
(pertinant part highlighted):
