Auto-place, or at least "semi-automatic"

autodeskguest

Hello,

 

In the spirit of the Thanksgiving holiday tomorrow first of all a major

thank-you to Cadsoft for introducing a hierarchical schematic sheet

structure. This will hopefully bring Eagle more into the mainstream and

it was "the" reason why I bought V7 (I was a V4 hold-out).

 

Since Eagle does not have an auto-place routine and Jorge Garcia said in

another forum that there aren't any really suitable algorithms for that

I have a suggestion for a simpler fix:

 

When switching to board view for the first time let Eagle scatter the

components the same way they are on the schematic, with multiple pages

in sub-groups. It's ok if that occupies a large area because people will

then be able to concentrate on one stage at a time, drag that over as a

group and arrange the parts as need. Then the next cluster. And so on.

 

Right now Eagle just plops the parts down in a willy-nilly fashion. It

looks like neat rows but the designators are all mixed up, the ratsnest

is a mess. This lengthens the placement job because one has to search

for many parts.

 

Also, I strongly suggest to let the "lesser versions" such as Eagle

Standard pre-group clusters outside the board area just to get a grasp

of what belongs together. Right now it refuses with an error message

"objects outside allowed board area". You cannot move one little thing

unless you move it into the board area. You can't even move it back out

if you grabbed the wrong part. Just let people arrange parts outside the

board area wherever they want but without routing permission. That will

uphold the license limitations because they can only route after the

affected parts have been moved inside the board area.

    (1) If you pick up a part and realise it is the wrong part before

    dropping it onto the board simply hit ESC and the move command will be

    cancelled and the part will go back into the heap.

     

    (2) If you have just dropped it onto the board, Undo (CTL-Z) will put it

    back into the heap. If its a few actions back you can select from the

    undo list and undo everything back to that move that took the part out

    of the heap and then re-do everything after that point manually again.

     

    (3) I created a ULP a while back (for these "lesser versions") that lets

    you remove a single element, automatically placing it below and left

    aligned with the heap. If there is no heap then it is placed left

    aligned with the origin and below it.  It works well but needs a review.

    I'll endeavour to upload it before Christmas(this Christmas) so keep an

    eye out for it.

    Ok, but that method would be rather clunky.

    Thanks, I will keep an eye out. If it can drop it back outside the board

    that would be great.
