Title: Filter By a Layer Color
Post by: MSTG007 on July 26, 2019, 07:57:22 AM
I am trying to figure out a way to select all the Color "8"'s in a drawing and then Change them to Color "47".

Just received new plotters and color 8 does not plot right for our pen styles in our department. (I know, we could change the CTB file but it is used company wide).

So to print, we need color 8 to be changed before we plot.

Any ideas? lol. Don't you love brain storming in the morning!

Thanks for your ideas.

thanks CAB,

I start looking into these.

Question is, I wonder if I should create a custom button that will execute the command before it plots.

You might want to use a network stored style file, update it once and everyone has the new version.

Also I do not know how your color 8 is setup but I would check to see what is causing the issue and look for a remedy rather than the band-aid. From a standards perspective it'll be a nightmare getting everyone to change their plotting style just for this issue.

My understanding is we no longer use a plotter "in a sense". Its a large format ink printer. So our Color 8 looks the same as our Color 9.

Code - Auto/Visual Lisp: [Select]
  1. (defun c:foo (/ d)
  3.   (vlax-for x (vla-get-layers d) (and (= 8 (vla-get-color x)) (vla-put-color x 47)))
  5.     (vlax-for b a (and (= 8 (vla-get-color b)) (vl-catch-all-apply 'vla-put-color (list b 47))))
  6.   )
  7.   (princ)
  8. )

@Ron: Re this line:

  1. (vlax-for b a (and (= 8 (vla-get-color b)) (vl-catch-all-apply 'vla-put-color (list b 256))))

Changing an object's colour property from colour 8 to ByLayer could potentially alter the resulting display colour if the object resides on a layer whose layer colour is not colour 8 - I would advise that objects with an overridden colour property should have such property changed to the new colour (that is, unless you were to test whether the colour of the layer on which the object is assigned is equal to the colour override).

Agreed .. that should have been setting the color to 47. Will update above *cheers*!

Forget the code make a copy of your ctb edit it call it your plotter name, you can set pen 8 to any of the 256 colors, we had various ctb's depending on where it was being plotted. Just click on the color.
