trouble with wires in Eagle ?

robb - 19 Oct 2007 19:41 GMT
so i am trying to use Eagle (latest freebie version 4.16r2)
to create a small schematic of  an old PCB.
( 4 ICs, 5 resistors, 12 buttons, couple diodes/ caps/ ribbon
connectors)

i added the components to the schematic and started wiring (with
problems)

Problem :
i can draw wires but the wires do not stick predictably to the
components and how do you join the wires ???

EG. i draw a wire to connect several components (i.e. component
pins) then i try to move some of the components and for one the
wire sticks and will follow the component  wwhen moved but for
another it leaves the wire behind ? when i try to fix by
re-dropping or moving the wire to the connection it does not stay
again

when i try to oin wires to others it does not seem to work ,that
is i can drop it onto the wire and it looks connected on screeen
but if you move the connected wire the joined wiree stays put and
will not follow move thus not connected.

what am i doing incorrectly ?

The Grid settings are wrong.
You need to set the grid to the default 50thou
Then place the components.
Currently the components are off grid and you cannot snap the wire to them.
You can salvage what you have by setting the grid to 1 thou.

Lots of schematic programs can do the near-miss thing, and most can
leave dangling wire segments. PADS can do neither. The only type of
schematic wire is a connection.

thanks John,
looks good but do they have an HE suite ? (hobby edition)
one that does not involve loans or leans :)

No, sorry, I think a package starts at about $5K.

- Use the "Net" command to connect, never "Wire".

thanks David,
that was the problem. i guess i am just not up to speed on the
schematics lingo.
i saw wire and  assumed it was used to wire things together.

now i am curious what a wire is for ?
thanks again ,

This trapped me badly also. Wires are *not* what you think they are.
They don't join to pads in Eagle. You need to use "signal", not "wire".

In addition, Eagle will, if you muck up the grid, create minuscule
connections when you join a signal to a pad, unless you drop exactly
on the centre grid point of the pad. The extra segment runs between
where you dropped (on the grid) and the active point on the pad - even
though you can't see the extra connection. Then when you drag the
component, it'll be those extra signals that get stretched, which is
very ugly. They should have been annotated internally as "extra", and
the drag should drag the intended signal to the nearest grid point,
before creating any necessary extra segments.

Bottom line is that you really should use a grid that will match
the exact pad locations of your component footprints. G*d help you
if you want to mix metric (say 1mm spacing) with imperial, say 1.27mm.
If you want that, you should first redraw the component footprint of
whichever chip is the odd one, using the grid you're going to use for
the rest of the board... or just make sure that you never need to move
it around once it's placed.

Hope this helps!

yes that was the problem exactly, i suppose i should have read
the instructions/manual

i guess i will read manual to find out what a wire is :)

Eagle sounds a bit poor, but what can you expect for nothing ?

Most CAD programs will capture the nearest pin to the net if it is
within say 100 thou.

No, Eagle is excellent, and will capture to the pin just fine, as long
as you don't use the ill-named wire feature, which isn't meant to.

The "capture to the the pin" is done by adding extra segments, which
aren't torn out and redone when you move the chip, and that's another
weakness. I wouldn't call it a bug, but it's certainly an inconvenience.

Lousy Spammer!

Stay on the grid.  I forget the exact units, but Eagle's schematic
capture uses something like a 1/1000th mil internal unit.  Wires only
connect if they exactly touch.  It's very hard to do that if you've
got any components off a grid.  Back when I used Eagle I had figured
out some CLI command to rescue off-grid items (once I orphaned the
entire power supply of a project by moving it all with the grid disabled
before I knew how to recover it).

It's far better developed and supported than your piece of software, Marra.

The claim that you're using ".Net 3.0 windows graphics interface" only applies
to your first image ("Click on a button to select a module..."), doesn't it?
The actual applications still run in DOS boxes, don't they?
Marra - 26 Oct 2007 01:06 GMT
You are completely wrong.

The software is a windows application using .net framework v3.0 and
Windows programming foundation.

The software is fully supported by email and phone.

If you find a bug I fix it and send you an update.
I cant think of any other company that does this !
And all for less than ?20 !

"If you find a bug I fix it and send you an update.

That's certanily commendable; companies' responsiveness to fixing bugs
certainly varies a lot these days... Eagle seems to be pretty good, as
Pulsonix ...mostly... is (and it's written using .Net as well) -- Cadence
and Mentor are pretty much the pits, of course.

So why don't your screenshots *look* like regular Windows... windows?  You
have a non-standard menu bar, no scroll bars, no resize "handle" widget in
the lower-right corner, etc.  I don't know of any other payware schematic
capture/PCB layout tool today for Windows that looks that way... perhaps
you've come up with what you think is an even better GUI than what Windows
provides?  (You wouldn't be the first -- back around 1992 or 93 I used EDA
software -- ProNet/ProBoard -- on Commodore Amiga computers that completely
ignored the standard Amiga windows menus and controls, substituting their
own...)

Why don't you place your users manuals on your web site?  If your software
really is any good, I'm sure it'll increase your sales.

Did you actually look at the website (http://www.cadsoftusa.com)? The
download area has a 248-page pdf "manual-eng.pdf" and a 71-page
"tutorial-eng.pdf" right there with the software in rpm and tgz formats.
There are also German versions.  Over in the User Download area, there's
a 418-page "eagle416r2_help_en.pdf", besides a number of other freely
downloadable documents in various languages.

As it happens, I use and like Eagle.  My previous experience has been
with pcad, autocad, and a couple of hobbyist-type programs.  I like the
freeware Eagle best of them all.  I hope someday to be able to be able
to pay for a pro-level version.

The software does what it says in the advertisement.
If it didnt I wouldnt have had 500 plus satisfied customers.

The software has been developed over 17 years.
The first version was 330,000 lines of assembler.
It was later converted to Delphi Pascal and then a couple of years ago
to C#.
Loads has been added as I have found a need for new functions.

That doesn't mean it necessarily does it as well as its competitors. :-)
You'll find me on here all the time whining about what crap ORCAD Capture is,
but I would admit that, indeed, it "does what it says in the advertisement."

> If it didnt I wouldnt have had 500 plus satisfied customers.

I'm sure that your product is worth the very low price you're charging.

But surely you'd still like to increase sales?  If only takes 10 minutes to
put up PDFs of your user manuals on your webs site.

If it's really as good as you suggest it's probably a bargrain at ten times
the current price!

But I am a non profit making outfit.
The software makes enough money to pay for PC consumables.
The software is sold at way under its marketable value.
I dont really want to sell masses of software as it is now just a
hobby.
I was a pro electronics and software engineer for 25 years and this is
just to keep my hand in.

My post would only be spam if I was making a living from the software
and I am not.
If people want to take advantage of the very low price then great, if
not I wont lose any sleep over it.

It doesn't work that way.  As far as I'm concerned at least commercial
spam is simply a rather large subset of the total.

Hi Marra,

OK, understood.

You might look into a couple different classes of licenses -- dirt cheap for
personal use, more expensive for commercial use.  Even if you're not
interested in the extra monies from the commercial use licenses, you could
donate it to a charity of your choosing and benefit someone without the
commercial user batting an eye at the higher price.

> My post would only be spam if I was making a living from the software

The idea was that you'd stick the PDF user's manual on that same web site
where you're advertising the software.  If you were to post it on
alt.binaries.sci.electronics (just ONCE! :-) ), that would be perfectly
appropriate too.

Heck, just e-mail me a copy... I'm j k o l s t a d 7 1 @ y a h o o . c o m ;
I'll be happy to stick it on a web site myself if you'd like.

I dont need to trash the competition.
The competition does it just fine on its own.
Had loads of people come across to me from numerous CAD packages.

They know that with me they will be fully supported.
I am happy to spend time with customers to help them, many other
companies dont want to know once they have your cash !

Type a command like "move IC1" (or whatever your part name is) then move
it with the mouse.   When you drop it, it'll be back on the grid.

Select the grid you need. Click the "Move" icon, press and hold "CTL" then
left click the off-grid item. It will jump on to your grid.
I use this a lot in package editor to move pads that were initially placed
on a metric grid that I later decided to place on a "close enough" division
(1/2, 1/4, 1/8, 1/16) of the default 0.1".
