How to Toggle Metal Layer Visibility Sequentially with Bindkeys?

You can use this code and call CCFsetToggleVisBindkeys(10) to set the bind keys:

procedure(CCFtoggleVis(layerName @optional (purpose "drawing"))
  let(((lpp strcat(layerName " " purpose)))
    pteSetVisible(lpp !pteIsVisible(lpp))
  )
)

procedure(CCFsetToggleVisBindkeys(maxIndex @optional (prefix "M"))
  for(ind 1 maxIndex
    hiSetBindKey("Layout" 
      ; modulus allows 0 key to toggle M10; beyond that
      ; doesn't make sense as would overwrite the earlier layers
      lsprintf("<Key>%d" mod(ind 10))
      lsprintf("CCFtoggleVis(\"%s%d\")" prefix ind)
    )
  )
)

Hi Andrew,

Thank you so much for your help – the script is working exactly as I need it! I have a couple of additional requests, if possible:

1. Would it be possible to extend the script to include the ability to toggle the visibility of the M0 metal layer? For instance, pressing the **  '  ` ' **key should toggle the visibility of the M0 metal layer while preserving the visibility of all other active layers.

2. Similarly, toggling the visibility of multiple via layers (from V0 to V10) pressing ** Ctrl + ' ` ' ** should toggle the visibility of the Via 0 via layer, pressing ** Ctrl + ' 1 ' ** should toggle the visibility of the Via 1 via layer again maintaining the visibility of all other active layers.

3. Additionally, is there a way to control the visibility of metal layers, via layers, and blockage layers using the middle mouse button click? This would provide a more intuitive and efficient means of toggling these layers.

Thank you once again for your response and time 

Best regards

I'd have hoped that you'd have been able to adapt the code to suit your additional needs (it is fairly straightforward). Anyway, I made a small modification to the code here:

procedure(CCFtoggleVis(layerName @optional (purpose "drawing"))
  let(((lpp strcat(layerName " " purpose)))
    pteSetVisible(lpp !pteIsVisible(lpp))
  )
)

procedure(CCFsetToggleVisBindkeys(maxIndex @optional (prefix "M") (modifier ""))
  for(ind 1 maxIndex
    hiSetBindKey("Layout" 
      ; modulus allows 0 key to toggle M10; beyond that
      ; doesn't make sense as would overwrite the earlier layers
      lsprintf("%s<Key>%d" modifier mod(ind 10))
      lsprintf("CCFtoggleVis(\"%s%d\")" prefix ind)
    )
  )
)

Now you could do:

CCFsetToggleVisBindkeys(10)
CCFsetToggleVisBindkeys(10 "V" "Ctrl") ; add the via bindkeys
; since the key used for M0/V0 is not going to be 0-9, just define a specific bindkey for these
hiSetBindKey("Layout" "<Key>`" "CCFtoggleVis(\"M0\")")
hiSetBindKey("Layout" "Ctrl<Key>`" "CCFtoggleVis(\"V0\")")

The last item (to toggle all metal, via and blockage layers) would need bit more work (it's not hard - just needs a loop to set the visibility of multiple layers and other objects in one go), but look at pteSetVisible documentation to do this - I'll leave this as an exercise for you (I don't have the time this week...)
