Is there a way to change display order of layers?

Former Member

Hi everyone,

 

I was just wondering if there was a way to change the order in which layers are displayed in Eagle.  For example, I'm trying to route a six layer, double sided board, and when routing the components on the Bottom, I need to have the Top layer displayed so that I don't place any vias underneath parts I've already placed.  However, having the Top layer displayed on top of the layer I'm trying to work on is distracting and sometimes confusing, so it'd be great if there's a way to have the Bottom layer displayed over the Top layer.

 

Thanks in advance!

    vias underneath parts I've already placed.  However, having the Top

    layer displayed on top of the layer I'm trying to work on is

    distracting

    and sometimes confusing, so it'd be great if there's a way to have the

    Bottom layer displayed over the Top layer.

    Hi James,

     

    While there is a very powerful alpha-blending engine under the hood, the

    implementation doesn't allow for many options like what you are suggesting.

    I use EAGLE just like you are suggesting (almost required for multi-layer,

    dense boards) I had to write a whole ULP and supporting infrastructure.  I

    have a ULP that maps to a quick key sequence that will increase the

    alpha-value of the colour for a given layer which means that one layer will

    be highlighted relative to the other layers.  Works great.

     

    But to do this I have to re-write the entire colour palette every time I

    use the key sequence.  And since the colour palette is stored with the

    installation, and not in the design files, no one else can really see my

    designs without reseting the palette indices (which I try to do before I

    send my files to anyone else).

     

    See these threads for a bit more info:

    I'll create a new thread again on eagle.suggest.eng and add your voice to

    the thread if you want to see this.

     

    Cheers,

     

    James.
