Topic: change nested block colour

[hudster]

Can anyone help me with this.

I'm trying to write a cleanup routine for use by non cad literate people.
I need a lisp routine that will change all all entities to colour 8 for use within xrefs, including nested blocks.

Does anyone have anything whivh will do this?

Cheers in advance for any help.

Look into nentsel. Also, you might try (car (nentsel)) and converting it to an object i.e. (vlax-ename->vla-object x) you won't have to decipher the dxf color. Just true color. Also, this topic seems more appropriate in the lisp forums, soooo....

May this one helps (doesn't work with attributes in Xrefs):

Code: [Select]

(defun MeChgBlkEntCol ( / AcaDoc BlkCol)
 (setq AcaDoc (vla-get-activedocument (vlax-get-acad-object))
       BlkCol (vla-get-Blocks AcaDoc)
 )
 (vla-StartUndoMark AcaDoc)
 (vlax-for Obj BlkCol
  (if (= (vla-get-IsLayout Obj) :vlax-false)
   (MeChgCol Obj BlkCol)
  )
 )
 (vla-Regen AcaDoc acAllViewports)
 (vla-EndUndoMark AcaDoc)
 (princ)
)

(defun MeChgCol (Obj Bcl)
 (vlax-for Ent Obj
  (if (= (vla-get-ObjectName Ent) "AcDbBlockReference")
   (MeChgCol (vla-item Bcl (vla-get-Name Ent)) Bcl)
   (if (vlax-property-available-p Ent 'Color)
    (vla-put-Color Ent 8)
   )
  )
 )
)Cheers
