can only display one layer's polygon plane of copper?

huayuliang

I often need view the only one rastsnested polygon of two layers, but the rastsnested polygon top layer will block my view.

such as I'm place via to connect ground plane between the top layer and bottom layer, and the other case..

 

of cause I can cancel the display of top layer, but I need view the top layer, just don't need process polygon when rastsnest.

 

 

it is too hard for my bad english..sorry.

    Hello,

     

    to bring the polygon back into the outlines mode, use RIPUP and click onto the polygon's contour.

     

    There are some options for RATSNEST and RIPUP that might help. I simply take it from the help:

     

     

     

    The RIPUP command changes routed wires (tracks) into airwires. That can be done for:

    • all signals (RIPUP;)
    • all signals except certain ones (e.g. RIPUP ! GND VCC;)
    • one or more signals (e.g. RIPUP D0 D1 D2;)
    • certain segments (chosen with one or more mouse clicks)
    • all polygons (RIPUP @;)
    • all polygons of certain signals (e.g. RIPUP @ GND VCC;)
    • all polygons except those of certain signals (e.g. RIPUP @ ! GND VCC;)

     

     


    Sometimes it may be useful to hide the airwires of selected signals, for instance if these will later be connected through a polygon. Typically this could be supply signals, which have a lot of airwires that will never be routed explicitly and just obscure the other signals' airwires.

    To hide airwires the RATSNEST command can be given the exclamation mark ('!'), followed by a list of signals, as in 

    RATSNEST ! GND VCC

    which would hide the airwires of the signals GND and VCC.
    To have the airwires displayed again just enter the RATSNEST command without the '!' character, and the list of signals: 

    RATSNEST GND VCC

    This will activate the display of the airwires of the signals GND and VCC and also recalculates them. You can also recalculate the airwires (and polygons) of particular signals this way.

    The signal names may contain wildcards, and the two variants may be combined, as in 

    RATSNEST D* ! ?GND VCC

    which would recalculate and display the airwires of all signals with names beginning with 'D', and hide the airwires of all the various GND signals (like AGND, DGND etc.) and the VCC signal. Note that the command is processed from left to right, so in case there is a DGND signal the example would first process it for display, but then hide its airwires.

    To make sure all airwires are displayed enter 

    RATSNEST *
