Issue on how to switch layer and place via without a middle mouse button on a Mac OS.

Hello,

I use Eagle 6.2 and I use a MAC OS.

I want to be able to switch between layers when routing pcb

connection wiring and automaticly get a via where I happens to have

my mouse pointer pointing.

 

When I google this I have found out that I use the middle mouse

button to do this.

Unfortunately there is no middle mouse button on my iMac mouse.

 

So, I was hoping to be able to use some shortcut key for this purpose.

If I go under the menu Options I can select Assign and that seams

like a solution.

But I do not know what commands I should use for this.

 

I want to press the key '1' to select the top layer and the key '2'

to select the bottom layer and also place a via at the same time that

I press '1' or '2'.

 

Can someone help me out how to do this or tell me some other smart

way to do this?

Niklas

Search for ASSIGN in the HELP

It demonstrates what you should do

The command you will need to assign is LAYER (see HELP again)

On a WINDOWS PC to have the F1 and F2 keys to do what you ask I would  type

into the command line the following:

ASSIGN F1 LAYER 1

ASSIGN F2 LAYER 16

The via is placed where the layer change happens (the place you need a via)

but it won't be where your mouse pointer is currently as the click that will

trigger the via is the one that confirms the  first segment of routing on

the new layer (makes sense). The via is place retrospectively.

Place the two command lines you decide on in your eagle.scr file in the BRD:

section. That way that functioanity will always be available

Hi Warren,

Thanks for your reply.

Well I cant make it to work.
I cant use F1.... as it assigned by the Mac OS to do stuff that I want the OS to be able to do. Increase brightness, lower the volume etc.

In option -> assign I select: "CMD + 1" : for switching to layer 1 by pressing the command button plus the '1' key.

I set the command to "LAYER 1" as you explained. (same as using the ASSIGN command but using the option menu to do it)

It sure switch to layer 1 but no via is placed.
So I expanded the command to say LAYER 1; VIA

But then only a via appear. No layer switching and the wire is lost.

Also tested:

LAYER 1;route

Or:

LAYER 1;route;via

Not working as I want it to work.

(e.i when trigger this button while I draw a connection wire I will jump to another layer plus dropping a via at the point where my mouse pointer is.)

I also tested the help file suggestion to do the following:

ASSIGN F7 'change layer top; route';

Well maybe I just do some syntax error when typing the commands? (I am new to Eagle).

If someone, not nessesarily Warren happens to have a working command to use on a Mac OS please share.

Regards

Niklas
