Eagle Software

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

  • Thanks for all your help so far.

     

    How do I change the units to Metric.   Is it possible?   Is it possible to make it default?

     

    I made the following changes:   DRC/ Sizes/ Minimum Width/5mil

     

    I got rid of all my errors.

     

    If I run ERC on schematic, 28 warnings, and no errors.

     

    If I run DRC on the board with the setting at 5mils, as mentioned previously, I do not get any errors.   Things are improving.

     

    Now I want to Autoroute, and I have what is referred to as the Freemium version.

     

    If I try to autoroute it appears to try to start, but it flashes momentarily and finishes with 0% routed.

     

    Can somebody identify what I'm obviously doing wrong.

     

    Thanks

    The answer is in the manual: GRID command

     

    Is it possible to make it default?

     

    Please refer to the eagle.scr that I mentioned above.  Second section of the EAGLE manual: Configuring EAGLE  See the subsection on Mode Parameters...

     

    It may help you if you navigate to the bin directory of your EAGLE installation and double click on the file eagle_en.htm.  That will open the EAGLE manual in your web browser.  Sections are hyperlinked together and I have found that the HTML version of the manual is a great resource...

    I so appreciate your response.

     

    But now, I'm starting to get upset.

     

    I'm sure in about 3 months when I work through every damm nuance of Eagle I'll appreciate what I have.

     

    I didn't realize the dimensioning tool has its own toolbar and you can select its own units.   I'm not sure I understand what value that would be, or why it would not default to grid units, but hey, I'm only a beginner.

     

    The same way I can't understand why Eagle can't auto adjust it's DRC rules to standard components, or the way it forces me to perform excessive mouse actions to perform the stop function.

     

    Give me a few days, I'm sure I'll have more suggestions.

     

    Thanks for all your help

    You're going to love this, but you can use different units for x and y... image

     

    Grid units are where things snap.  I don't always want dimensions to be the exact same as the snap grid.  Heck, I'm usually using EAGLE 5 and it doesn't have the dimension tool...

     

    As for stop, are you clicking the stop button or doing something else?

    Because there's no such thing!

     

    The design rules are there to impose limits on what you are allowed to

    do - things like "no tracks thinner than 0.01 inches" or "no gaps

    narrower than 0.005 inches". These are not universal - they depend on

    your chosen board house's capability (and all professional PCB fabs are

    much better than home etch, which Eagle can cope with).

     

    If you are fitting an EM11B rotary encoder with two sets of through-hole

    pins at 0.05" (1.27mm) spacing on a board you intend to etch yourself,

    the only sensible thing for Eagle to do is TELL YOU that it's not going

    to work. Adjusting the rules you carefully worked out to suit a

    component you picked on a whim would be catastrophically stupid.

    Yes Rob, I agree, how stupid of me.

     

    Why would I not expect Eagle to impose a limit on me based upon an action I have never performed: Adjusting the rules you carefully worked out to suit a component you picked on a whim.

     

    Do me a favor!

    Do yourself a favour and READ THE ADVICE YOU ARE GIVEN.

     

    We are not here to waste our time on your personal whinge-fest. If you

    want to know why things are as they are, and somebody answers that

    question, rejecting an answer you don't like with sarcasm is incredibly

    rude and obnoxious. Please grow up.

     

     

  • in reply to autodeskguest

    I'm going to make this really simple for you.

     

    The next time anybody refers to anything I'm questioning, wanting to do, or thinking you should be allowed to do as catastrophically stupid, they will get an attitude from me.

     

    You don't have to act like you are the defenders of eagle.

     

    Everything about Eagle is not the greatest.

  • in reply to autodeskguest

    I want to clarify.

     

    I have been reading the advice given.   I have not rejected anything.   I'm here to learn how to do things.

     

    And I have tried to thank everybody who has helped me.

     

    None of these 4 things requires me to like Eagle.

     

    And I don't have to justify anything I would like to do.

     

    Now that we have that straightened out, if you don't want to help, don't!!!!

    LOL, but this is the EAGLE forum - we *ARE* the defenders of EAGLE!

    In some circles, that comment would be worthy of the title "troll"...

    Seriously though, what other EDA products have you used, why are they better than EAGLE, and why aren't you using them?
