Eagle Software

e14 Contributor
e14 Contributor over 12 years ago

Greetings

 

My name is Brian, and I am a new user of Eagle, for right now the free version.

 

First question, is there any way to stop Eagle from carrying on point to point connections.   I am sure at times this is a very useful feature, but I need it to stop after automatically after it connects 2 points.   I hope this is possible, as if this is a persistent feature, it will really turn me off to Eagle.

 

But more importantly, I did a practice design and have a problem.

 

I am using a XF2H-3415 surface mount connector, .5 mm spacing.   I have a bit of a problem with the datasheet, as it doesn't clearly state the measurement units, but since the first page notes a measurement in mm, I'm assuming they are smart enough to carry those units throughout the datasheet.

 

Let me describe what I did, and perhaps did not do.

 

I have my board layout done, I have two 12 pin single row headers on each side of the board, and the other connector on the other side.   And I see the Ratsnest.

 

I think the pad color denotes side of board, but I'm not sure how to check or change that.

 

This is where the confusion starts.

 

I can't get the autorouter to start, and I come up with 34 DRC errors.

 

I'm a beginner, probably making a silly mistake, but Eagle also has a much more complicated set of DRC rules than I'm used to.

 

I have attached an image.

 

Help is most appreciated.

 

Thanks

 

Brian K

    I really don't understand your response.

     

    I've not ignored, nor have I tried to be unappreciative of any advice or directions directly relevant to a problem I was trying to solve.

     

    But if you want to get into a debate about underlying philosophy and default settings, I'll take this as far you want.

     

    I'll call technical support from now on, open till 7pm est.

     

    I wont have to put up with their attitude, and they get paid to put up with mine.

     

    What do you think you offer that they can't?

     

    And who do you think you are to me.   I have helped plenty of people in my time I wouldn't spend 2 minutes with if I didn't have to.   You think you're any different?

    I won't.  It seems you've pretty much burned all your bridges here.

    Hi Chuck

     

    I appreciate your response, but

     

    Nothing is going to make feel better about the way Eagle is defaulted.   You could spend all day teaching me how to set up my design rules, I would certainly appreciate and learn something from it, but it wouldn't change my opinion about the default parameters.

     

    Perhaps the clue here is right in something you said.

     

    "But many of us use bench-top etching systems to fab our own

    boards.  I used to do this with PTH boards.  Once I moved to surface

    mount, I couldn't achieve the tolerances required so I've had to use a

    real board fab house."

     

    real board fab house?????

     

    Is this what Eagle is initially set up for, amateurs and hobbyists etching their own boards.

     

    Don't be insulted, hear me out.

     

    Perhaps when Eagle initializes, it might try setting itself for default rules according to how the user is going to have his boards made.

     

    Perhaps even a warning that the default rules don't reflect current manufacturing capabilities

     

    I appreciate your response, you told me how to change things.   You can do nothing more, please don't try.

     

    Sincerely

     

    Brian

    Here is where I'm having a problem with the design rules.

     

    This particular part that was giving me problems was obsolete 7 years

    ago.  It has been replaced with the M model, but the spacing is the

    same.   This particular obsolete part has been around 10 years.

     

    What legitimate board house could not handle that spacing.

     

    Most can.  But many of us use bench-top etching systems to fab our own

    boards.  I used to do this with PTH boards.  Once I moved to surface

    mount, I couldn't achieve the tolerances required so I've had to use a

    real board fab house.

     

    So let me retract my question, why are the DRC rules not self

    adjusting.   I could further debate the point, but I wont.

    Self adjusting to what?  Just automatically change the tolerances so DRC

    doesn't produce errors?  That would defeat the purpose of DRC.

     

    I never changed the DRC rules.

     

    Perhaps you should change them to what suits your design.  10 mil

    spacing is fine for PTH boards.  SMD boards clearly need smaller tolerances.

     

    Now my question is this.

     

    Why would Eagle default to parameters that don't reflect current

    manufacturing capabilities.

     

    Is that spacing really beyond typical manufacturing capability?

     

    If it isn't, I was caused unnecessary trouble by the parameters it

    defaulted to.

     

    If you don't like the defaults, change them.  You can do so through the

    control panel.  In the tree, expand Design Rules, double click

    default.dru and edit as necessary.

     

    HTH,

        - Chuck

    Seriously though, what other EDA products have you used, why are they

    better than EAGLE, and why aren't you using them?

    You should really listen to yourself.

     

    I haven't refused any advice, or ignored anything that was told me that was relevant to my needs.

    And maybe this will help you.   Was there a necessity for this response.   Did I insult you because I didn't give you the respect you think you deserve?   I moved to Eagle because my Multisim / Ultiboard combination has become unusable due to package type availability, and that is the only reason.

     

    I much prefer it over Eagle, of course when Multisim was purchased by National Instruments the price escalated.   Like most people I have to move to what I can use and afford.

     

    You have any other questions?   And you can take your laughing out loud or lots of love, like I know which it is, and stick it

    I'm always amazed by some people for whom the HELP section included in most software in unused.

    The same people expect others to guide them through a learning process, but then bite the hand that feeds them.

     

    You tried your best Doug, now its time to let Brian discover it on his own.

     

     

    No I'm not an expert on Eagle and I'm learning it as well, but I've used the help section to find out many things.

    Like everything you don't know, it takes time to learn and this is no different.
