Have a question about CadSoft EAGLE?  Ask our Expert, Jorge!

Jorge,

Can you please refer me to a comprehensive manual(.pdf preferred) for EAGLE Professional 6.5 in English?

The ones I have been able to get are either incomplete, or are written in German.

I appreciate having the community here for help but I am not the one to bother people thus opting to study a well-written OEM guide.

It has been many years since I have used EAGLE for any work project. I am almost ready to give up on EAGLE and buy Orcad which I was company trained to utilize.

All I need is a complete guide.

Thank you in advance,

Emjay

Emjay: You have seen the manual PDFs that are installed with Eagle, at [Eagle Install Directory]\doc\manual_en.pdf, and also tutorial_en.pdf?

My apologies. The version is 6.3 not 6.5. And yes I have. The technical writing is not coherently structured to seamlessly flow from process to process in detail.

Thanks,

Emjay

Hello Jorge,

I am doing fine and feeling great! Soaking up a lot of this sunshine in my sunroom laboratory from a long wintry hades.Thank you for asking. Same to you Sir. I appreciate your expertise as well as the fast response. Jorge, may you have a wonderful rest of your day followed by a great weekend!

If anybody has found anyway around that I would be more than happy to

I don't know for certain, but I think somehow there might be some kind of coordination between the EAGLE Central account and the Element14 account.  When I post from either place, it seems to be correctly attributed.  (For example, I posted this from the EAGLE Central site: Re: Essay on the Eagle Interface   You can tell by the signature block where it came from.)  You might contact James to see if that's it.  (NOTE: I don't access the NNTP groups directly.)

I'd love to see a solution to posting lists and source code snippets so that they can be read on both/either Element14 and EAGLE Central.  For example, I posted these Element14 links from Element14:

Element14: Re: Essay on the Eagle Interface

But nothing showed up on the NNTP feed:

EAGLE Central Forums: eagle.suggest.eng » Essay on the Eagle Interface

Same for source code snippets.  Github gists look good on Element14, but don't seem to get propagated to the NNTP groups...

Jorge often posts as "CadSoft Guest", so actually the reply you read may

have been from him.

Now I asked if the resizing of the grid will affect the component's

size? which I never got a response back from Chuck.

I appreciate dealing with you on this subject being you are kind enough

to respond when you can.

 

I built the component using 1 mil increments on the symbol instead of

keeping it at 0.1". Chuck's instruction set is clear I only need to know

will it affect the size of the component.

I also need to know why is it that when building a component one must

use 0.1" when like in my case the component is a micro-smd which the

package measures in millimeters and the pads measure in mils, which is

why I used mils?

 

I built the component's pads using mils(as the pads are 9x12mils in

dimension) but I am instructed by Chuck to built the entire symbol using

0.1" which doesn't make sense to me.

Hi Emjay,

I hope you're doing well. Chuck's suggestion is correct and here's the why.

As far as the schematic symbol goes, its not necessary for it to match

the physical parameters of the real component. The goal with the symbol

is to aid understanding of the design.

In the schematic the 0.1"(2.54mm) grid recommendation comes up because

all of the symbols in EAGLE's default libraries are made to that grid,

so if you use a different grid spacing the pins aren't going to line

properly which will make connections almost impossible. In order for a

connection to be valid in the schematic nets must start and end on very

exact points if you're off by a hair the connection won't be defined. By

using a 0.1" grid you insure that your pins are always on grid and your

connections are reliable.

The grid in the schematic has no bearing on the grid in the layout. For

the layout you need to use whatever grid is convenient and the package

you use for a component must match it's physical parameters precisely in

order to make a useable board.

As you can see the grid in the schematic will have no effect on the

package size so your layout will still be accurate sized even if your

schematic symbols are larger for the sake of readibility and understanding.

Let me know if there's anything else I can do for you.

Best Regards,

Jorge Garcia

Thank you Graham. Much appreciated. I have the entire schematic done with exception of this one issue so porting it over to OrCad will not be a problem.

My bank card is out with Cadence(Industry leader) on the phone. Should have known better dealing with a German company & its product. I support American companies. Much appreciated Graham. Take care and have good one!
