Did you download the manuals too ? Much fuller than the
in-built help

And if you don't like it, fully refundable ;-) Heck, you could
put that $0.00 back in the coffers right now, ready to spend
on the next freebie

I guess not, I tried to read the turtorial but gave up. Trial-and-error gave
the answers much quicker.

Not for me, for now.

But still, I'm getting the idea that the tutorial is for the absolute
beginner, and is set up in an illogical manner.

Which brings me to this question: how can I fatten up the ground net or any
other net or trace for that matter? The "change" feature is completely
blurry to me, and every attempt to "change" anything results in an illogical
action. Boy, is that user interface illogical!

The autorouter, however, absolutely rocks! But what do all those cost items
mean?

Next question: on a single sided board, how can I insert bridge wires? I
only need 2 or 3 in order to stay single sided for my current project.

Anybody who has only a tiny bit more experience might easily answer these
questions.


Regards,
Joris.

Do:

 Change | Width | <value>

from the command line or the menu.

Can someone answer him about bridge wires (I've only
done single sided boards)?

I just had an idea - what about just wiring on the
bottom for single sided - and your 'bridge' wires
will be on the top and connected with wires using
the pads that will show up as the vias?

Couldn't you just insert a 0 ohm resistor in the signal you need to
bridge?

Hi-
1/ I don't have a problem with the change feature.  Choose: change, width, 0.04
(say), and left click on a board trace, it should immediately change width.  You
will need to touch each segment of the trace.  You can define classes, eg power,
and make them different widths.
2/ the cost items allow you to mofiy the behaviour of the autorouter, so if you
want less vias, you just make them more expensive, etc.  Sounds real simple ...
3/ to do single sided you set the prefeerences in the autoroute (1st page) -
means you want this side to be horizontal traces, | vertical, / diagonal, * any
direction, N/A NONE.  So, you want N/A.

From one newby to the next,
David

Workable I suppose, but the parts list will start
to build up and the name for the signal/trace won't
be there from start to finish.

I think using the bottom (blue) for the *real* trace
and the top (red) for the 'jumper' traces is the way
to go (or vice versa) - one can set the via pad size
and drill size as required for the guage of the 'bridge'
wire to be used.

But, again, all I've ever done have been double-sided
boards and this has just been conjecture on my part!

Jim

Ah, that's a help.  In my case I was confused because there didn't seem to be
any way to select anything.
One question:  is there a way to define your own pad shapes?

Regards,
Colin

No, but there is a selection of pad shapes.  While in the board layout, Edit>Design
Rules>Shapes and you can override the pad shapes.

I tried laying out a board with one layer, and it kept getting stuck.  I manually
inserted a trace with vias to the top, and then continued the autoroute.

By the way, centre mouse button will change from botoom to top while manually
laying traces.

Hi,  Joris!

The method Jim mentioned  works. You simply route on bottom side to the
point where you want to have  bridge wire, click once to stop there, then
you click on LAYER window (you drag the wire with you, but that doesn't
matter), click on TOP layer and continue routing. Signal wire will change
colour and pad will be inserted there automatically. You route the bridge
wire and then you once again change layer to BOTTOM the way I described
before. You can change size and shape of the VIA pad by clicking
EDIT/CHANGE, then SHAPE or DIAMETER or DRILL, choose what you want and left
click on the pad. But I preffer  to do that a bit differently - I first
place pads ( before routing ) to the place I want that bridge and then route
the wire the same way as above. Hope that helps, regards,
                                                                                                               Samo

Yes, using the top layer for your links is exactly the right way to route a
1 sided board.  There are also some autorouter control files that will
create straight tracks on the top layer, useful for autorouting a 1-sided
board.

Look on the EAGLE download section for 1-side.ctl or a similar file, and try
out the autorouter.

I just had a look in the "Jumper" library.  I think what you need is under "J".
