Method to change hatch background in multi block to none...

[wee]

I have a drawing that was exported from Revit that has multiple blocks with a hatch background set to a color and I need them all set to none. I can use the blockeditor and do them one at a time but there are over 1000 blocks. Looking for a way to get them all at once. Small example file attached.

 

Thank You

Brian

Like this?

(defun c:effh (/ a c d)
  ;; RJP » 2020-11-16
  (vlax-for l (vla-get-layers (setq d (vla-get-activedocument (vlax-get-acad-object))))
    (cond ((= -1 (vlax-get l 'lock)) (vlax-put l 'lock 0) (setq a (cons l a))))
  )
  (vlax-for b (vla-get-blocks d)
    ;; This line will only process block definitions
    (if	(= 0 (vlax-get b 'isxref) (vlax-get b 'islayout))
      (vlax-for	o b
	(cond ((and (vlax-write-enabled-p o) (wcmatch (vla-get-objectname o) "AcDbHatch"))
	       (setq c (vla-get-backgroundcolor o))
	       (vla-setrgb c 0 0 0)
	       (vla-put-backgroundcolor o c)
	      )
	)
      )
    )
  )
  (foreach l a (vlax-put l 'lock -1))
  (vla-regen d acallviewports)
  (princ)
)

That helps but deletes the hatch, I would like to leave the hatch just set the background color to "None".

Post an example drawing of before and after of what you're looking for.

while I am using this, all hatches will add background 0,0,0. if there is no background colour also will be changed to this 

 

 

 

 

I have different Hatch background colours. Someone is true colours someone is index colour and someone is without background colour (none).
Need all hatch without background colour (need to set none). but I don't want to change any hatch type, pattern, and general colour. need to change background to none

I'm not sure I follow .. the code HERE does that already? Nevermind .. I see what you are saying... let me take a look.

 

Try this version:

(defun c:foo (/ a c d)
  ;; RJP » 2023-08-13
  ;; Sets hatch background color in blocks to 'none'
  (vlax-for l (vla-get-layers (setq d (vla-get-activedocument (vlax-get-acad-object))))
    (cond ((= -1 (vlax-get l 'lock)) (vlax-put l 'lock 0) (setq a (cons l a))))
  )
  (vlax-for b (vla-get-blocks d)
    ;; This line will only process block definitions
    (if	(= 0 (vlax-get b 'isxref) (vlax-get b 'islayout))
      (vlax-for	o b
	(cond ((and (vlax-write-enabled-p o) (wcmatch (vla-get-objectname o) "AcDbHatch"))
	       (setq c (vla-get-backgroundcolor o))
	       (vla-put-EntityColor c -939524096)
	       (vla-put-backgroundcolor o c)
	      )
	)
      )
    )
  )
  (foreach l a (vlax-put l 'lock -1))
  (vla-regen d acallviewports)
  (princ)
)
