Topic: Layer Filter count

[Matt__W]

Anyone have a quick and dirty LSP to count the total number of layer filters within a drawing (2016)? I'm trouble-shooting a DWG and there must be a few HUNDRED layer filters in it and I was curious as to exactly how many.

Thanks!

Code: [Select]

(vlax-get (vla-Item (vla-GetExtensionDictionary
      (vla-get-Layers (vla-get-ActiveDocument (vlax-get-acad-object)))
    )
    "ACAD_LAYERFILTERS"
  )
  "COUNT"
)

Thanks!
No wonder the drawing is so slow when copying/pasting.

Command: (vlax-get (vla-Item (vla-GetExtensionDictionary (vla-get-Layers (vla-get-ActiveDocument (vlax-get-acad-object))))"ACAD_LAYERFILTERS") "COUNT")
16087 <<<<<

To help put things in perspective, there are maybe, MAYBE, a dozen layers in this particular drawing.
