hide a net?

fritzz Level 5

I know I can SHO to highlight, but is there a way to hide all routed nets except fot VCC and GND?

    Select a signal, open the properties window and flag "airwires hidden".

     

    Read the help about "RATSNEST" you'll find other information about

    hiding airwires...

    I don't want to hide airwires. I want to hide all *routed* nets, except for VCC and/or GND.

    You can only hide layers.

    You can't hide routed traces and leave only, say, VCC and GND showing.

     

    You can get SHOW to highlight both simultaneously

    SHOW VCC GND

    This may be what you are after.

     

    Another option is to make use of the ULP copy-layer-to-any-layer.ulp

    Make a new user defined layer, say 100

    Use the ULP twice.

    First time through copy Layer 1 VCC and GND traces to layer 100

    Second time through copy Layer 16 VCC and GND traces to layer 100

    You will see VCC and GND much like the higlighting of SHOW. To get a view

    like you requested turn off layer 1 and 16. Downside is the problem of

    editing layers 1 and 16 after this. It's a bit messy as layer 100 needs to

    be managed also.

     

    Another technique that comes to mind is to temporarly change palette colour

    for the un-highlighted colour of the layer to one close or equal to the

    background. When you go SHOW VCC GND it will be a view close to what you

    are asking for.

    Trouble is you loose this highlighting of VCC GND as you attempt edits. The

    up-side is you can easily get it back with an 'up arrow' if you previously

    typed SHOW VCC GND in the command line so in practice it's quite usable.

    The downside is you really need a ULP to manage the changing and restore of

    the palette colours.

    So you want to hide traces rather nets.

    I think it's not possible, anyway what's your purpose?

    If you hide some tracks you cannot route anything else because you may

    overlap them easily.

     

    Perhaps there is another way to fix your issue.

    I'd like it just to be sure I hae made good choices in routing these important nets. The highlight on my monitor is hard to see.

    Define other colors so you can see the highlighting better.

    Can I somehow keep the regular color, but change just the highlighted color?

    Sure can.as they are defined separately.

    The palettes are a bit tricky. Read the manual to understand them.

    In essence the first row of the palette is 'normal' or lowlight.

    The next row is the highlight for the previous row.

    The third row is lowlights again and the forth row is their highlighted

    color.

     

    Then there is a consideration that I cannot find a previous mention of.

    If you turn off alpha blending the following happens

    When an object is highlighted it does not appear in the color of the

    palette, as expected.

    i.e. That object is not redrawn in the expected highlight colour.  When

    highlighting, an object is replicated and placed on top of the chosen

    object. As  you have one object on top of another the bits of the color

    codes are ORed together(Assuming the black palette).

     

    Have a look at the default red for the TOP layer. The RGB components are

    200,50,50

    The highlight red is 255, 0, 0

    But when you analyse the resultant color it is 255,50,50

    Be aware of this interaction of the normal and highlighted colors. Odd

    results can happen.

     

    Something that may work for you

    lowlight red 200,50,50

    highlight 50,50,200 ( The blue color normally used for lowlight Bottom

    layer)

    When ORed during the highlighting process you get a bright Magenta color.

    You see this color happening normally when a trace on the Top layer crosses

    a trace on the lower layer(default colors assumed)

     

    You said earlier you had problems discerning the highlighted objects on your

    monitor. Many users turn off alpha blending, this helps with brightness.

    Experiment to find something you can livewith.
