How to change all wires?

I 'am using Eagle 5.11

 

In my layout I have many traces with  WIDTH of 0.2mm.

Now I would like to change all that wires  in WIDTH 0.15mm.

I know I can do that with the command  CHANGE and GROUP but is there an

other way ?

With GROUP some other wires ( for example WIDTH of 0.5mm ) change too.

 

THANKS

Also, you should look into classes, by assigning nets to a certain

class, you can control width and clearance for that class. that way your

hi current or power nets don't need to change with your signal nets.

maybe this is what you are really looking for.

also, you can group by box and then ungroup certain elements, but I

don't remember how to do it, it is possible though.

I don't think so:

- Modifying classes does not change anything that is already routed;

- Class widths are used /only/ by the autorouter and have absolutely no

  effect when routing manually.

I somewhat agree with Gary. I use classes myself, but it needs to be

followed up with ULP's. I have ULP's for grouping classes (on specific

layers), and with that I can easily change width of a class,, no matter what

it used to be. It is very useful when doing impedance match and when you

play with stackup materials and distances.

You are right - but without additional ULPs, using classes wouldn't

solve the OPs problem.

(And even for what you described, the previously mentioned width change

ULP can be restricted to a particular signal - so for most cases it

should be sufficient.)

Thanks all for the information.

But I was thinking there maybe  a ULP so you can change all wires with width

0.2mm into 0.15mm without selecting all the wires seperate.

The mentioned ULP does it both ways. I'm referring to the ULP bundled with

Eagle v5.11 The ULP dialog has 1.5.1 as a version on it. The version that

came with v4.16R1 looks similar.

So you either:

- select the signals of interest

- or select none but check the box below ("Change without Signal name") and

you then enter the range in the bottom two fields. The fields are

'inclusive' so for your example above put 0.15  in the first box and 0.2.

Note the Units are whatever your board is in currently i.e.. mm  inch  mil

or mic

All the best
