Eagle board layout newbie question

  1. Hello everyone.
    Hope someone can give me some pointers:
    I'm trying to position components on the board in some kind of orderly
    fashion, a pattern rather. The most important are the few LEDs , but for the
    rest of them I'd also like it to look good from an aesthetic point of view.

    Here is my problem: I cannot find a way to align components in the board
    layout window. I mean, you can move them, and they stick to the grid, but
    that's about as much control over positioning of the components as you have.
    Unless I'm missing something.

    Is there a way to select a group of components and run a command like any of
    the desktop graphic editors would have: align top, align center, align
    bottom, distribute equi-spaced, distribute centers etc, you got the idea. Am
    I asking too much of Eagle? Can someone please recommend a board layout
    software that is capable of more precise components placement if Eagle can't
    do?

    Thanks a lot to all responded!

    Pulsonix will do what you want:

    http://www.pulsonix.com

    apart from equi-spaced distribution (next version should have it)

    and EasyPC will do most of it:

    http://www.numberone.com

    considerably cheaper. Both are from the same parent company.

    Hi Leon,
    Thank you for the suggestion.
    The prices for both systems are way over my head, considering I'm a
    hobbyist. That was the reason Eagle got picked. I would consider another
    software if it can be kept as inexpensive as possible.

    So, is it definitely not doable in Eagle?

    I just checked with the copy I have, and it doesn't look like it. EasyPC
    starts at under 100 GBP (500 pins limit), which is about the same price as
    Eagle.

    AFAIK, not provided in Eagle.

    One time I wanted a uniform circle of LEDs, so I created a little
    basic program to calculate the positions using sin and cosine. I
    wrote out the results to a script file in the form:

    move d1 (1.125 2.125);
    move d2 (1.50768 2.04888);
    move d3 (1.83211 1.83211);
    move d4 (2.04888 1.50768);
    move d5 (2.125 1.125);
    move d6 (2.04888 0.742317);
    move d7 (1.83211 0.417893);
    move d8 (1.50768 0.20112);
    move d9 (1.125 0.125);
    move d10 (0.742317 0.20112);
    move d11 (0.417893 0.417893);
    move d12 (0.20112 0.742317);
    move d13 (0.125 1.125);
    move d14 (0.20112 1.50768);
    move d15 (0.417893 1.83211);
    move d16 (0.742317 2.04888);

    Then all I had to do was execute that script within Eagle board
    layout to move my parts before routing the board.
     
  6. Leon,

    Eagle is Free (0 GBP) in its hobbyist configuration.

    That's a great suggestion, David. I guess, I should spend more time
    learning the command language in Eagle. That would work perfect for me.
    Little cumbersome, but manageable.

    Glad you like it. Here's another trick:

    Since mouse clicks snap to grid, if you have a component misaligned
    relative to the grid (for instance, if you have changed the grid to
    a funny number) it can be tricky to move it where you want. Click,
    move, click leaves it still misaligned by the same amount, since
    both clicks were grid-relative.

    Instead, type
    move d1
    then click where you want it. The component is selected by its
    origin point, then dropped exactly at the grid snap point.
    Combined with suitably chosen grid, that may get you some of what
    you want.
