    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?
  2. 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.
  4. 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

    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.

    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.
