Anyone have anything that will save/restore layer states for xrefs ONLY?

I don't have one, but one could be written pretty easily I would assume. Just store the information in a dictionary within the drawing, and then you can call it when you opening it fresh again.

Code preferably... Not too keen on running something that I don't know what it'll _really_ do.  No offense.

This would just be like a one time thing.  It doesn't need to be run every time the drawing is opened.

How do you know which layers are supposed to be on/off frozen/thawed?  The information could be stored in a global variable, and then just called by a program to restore/save.

How are you visioning it working?

I don't remember fully but don't layer names with $ or | in them represent
attached or overlay xrefs?  Otherwise you just get the layer info through
normal means, with the addition that you need to check group code 70
bit 5 to see if the layer is dependent on an attached xref.

What I'd like to do is basically match another drawing's layer states for selected xrefs.  The more I think about it, the more I realize I'm not sure how to approach this.  I could do some sort of DBX thang that loops through layers checking them against the good drawing's xref layers?  Or maybe save an external file and restore......whenever??  I dunno.  I guess I'm open for suggestions.

If you just want to copy from one drawing to the current, than that shouldn't be too hard, as long as the xrefs are named the same.  If not, then some mapping will come into play.  This could be done with VBA ( stated because I know you can code in it ).  If that is what you are after it wouldn't be too hard to come up with something.  Do you want to code it in VBA ( I can't really help, but give some ideas that I would use with Lisp and ActiveX )?  Or do you want to do it in Lisp?

Are you just doing for one drawing one time?   (If am I reading you correctly)
IN that case creat and then export a layer "filter" from the "to be match" drawing and then import that filter into the file to the matching.  But I am probaly all wet. 

I will go back to drooling this :-D
I + XI = X is true ...  ... if you change your perspective.

That would give me EVERY layer... I just want the xref layers.

Have a look at the following:

The following code opens and closes a DBX document

Code: [Select]
;;; Open a dbxDoc ;
;;; use (setq dbxDocument(kb:OpenDbxDocument dwgname)) ;
(defun kb:OpenDbxDocument (DwgName / app doc dbxopen dbxDoc)
  (setq app (vlax-get-acad-object)
        doc (vla-get-ActiveDocument app)
        )
  (if (/= dwgname (vla-get-fullname doc))
    (progn (cond ((= (substr (getvar "ACADVER") 1 5) "15.06")
                  (setq dbxDoc  (vla-GetInterfaceObject app "ObjectDBX.AxDbDocument")
                        dbxopen (vl-catch-all-apply 'vla-open (list dbxDoc DwgName))
                        )
                  )
                 (t
                  (setq dbxDoc  (vla-GetInterfaceObject
                                  app
                                  (strcat "ObjectDBX.AxDbDocument." (substr (getvar "acadver") 1 2))
                                  )
                        dbxopen (vl-catch-all-apply 'vla-open (list dbxDoc DwgName))
                        )
                  )
                 )
           (if (vl-catch-all-error-p dbxopen)
             (setq dbxDoc nil)
             )
           )
    )
  dbxDoc
  )

;;; Close dbxDoc
;;; (kb:CloseDbxDocument dbxDocument)
(defun kb:CloseDbxDocument (dbxdoc)
  (if (= (type dbxDoc) 'VLA-OBJECT)
    (progn (vlax-release-object dbxDoc) (setq dbxDoc nil))
    )
  )

This code will return a list of layer names to change.
arguments: xref; "*" returns ALL layers
                       nil returns the active doc layers only
                       "xr" returns ALL xref layers (filters "|")
                       "xrefname" returns only the layers of a single xref (filters "xrefname|")

Code: [Select]
(defun kb:GetLayerList (xref / layers ret)
  (setq layers (vla-get-layers (vla-get-activedocument (vlax-get-acad-object))))
  (cond ((= xref "*") ;gets all layers
(vlax-for x layers (setq ret (append ret (list (vla-get-name x)))))
)
((= xref nil) ;gets only active doc layers
(vlax-for
x
layers
   (if (not (vl-string-search "|" (vla-get-name x)))
     (setq ret (append ret (list (vla-get-name x))))
     )
   )
)
((= xref "xr") ;gets all xref layers
(vlax-for
x
layers
   (if (vl-string-search "|" (vla-get-name x))
     (setq ret (append ret (list (vla-get-name x))))
     )
   )
)
(t ;gets a specific xref's layers
(vlax-for
x
layers
   (if (vl-string-search (strcat xref "|") (vla-get-name x))
     (setq ret (append ret (list (vla-get-name x))))
     )
   )
)
)
  ret
  )

This code will match the layer in the active drawing, local and / or xrefs, with the states of the layers in the dbx document.

arguments:
lstatename - the Layer State to use
dwgname - the drawing to be referenced (dbx doc)
layerList - which layers to change: see above.

Code: [Select]
(defun kb:LayerStateEngine (lstatename   dwgname layerlist     /
    dbxdoc   dbxdict dict       dbxplotstyles
    dbxlayernames dbxlinetypes
    )
  (setvar "clayer" "0")
  (princ "\nSetting the current layer to 0")
  (princ)
  (setq dbxdoc (kb:OpenDbxDocument DwgName))
  (if dbxdoc
    (progn (setq lstateobj (vla-GetInterfaceObject(vlax-get-acad-object)(strcat"AutoCAD.AcadLayerStateManager."(substr (getvar "ACADVER") 1 2))))
   (if lstateobj
     (progn (vla-setdatabase lstateobj (vla-get-database dbxdoc))
    (vlax-invoke lstateobj 'restore lstatename)
    (setq dbxlayers (vla-get-layers dbxdoc)
  layers    (vla-get-layers (vla-get-activedocument (vlax-get-acad-object)))
  )
    ;get a list of layers in the dbxdoc - because there's no "has" method!
    (vlax-for
   x
    (vla-get-layers dbxdoc)
      (setq dbxlayernames
     (append dbxlayernames (list (strcase (vla-get-name x))))
    )
      )
    ;(setq n "X_Base43|A-Wall-Patt")
    ;(setq n(nth 3 layerlist))
    (foreach
   n
    layerlist
      (if (and (not (= n "0"))
       (member (strcase (kb:striplayername n)) dbxlayernames)
       )
(progn (setq lobj    (vla-item layers n)
     lobjdbx (vla-item dbxlayers (kb:striplayername n))
     )
       (foreach
      property
      (list "Freeze"   "LayerOn" "Lineweight"
    "Lock"   "Plottable" "color"
    )
(vlax-put lobj property (vlax-get lobjdbx property))
)
    ;set plotstyle
       (setq ps (vlax-get lobjdbx "PlotStyleName"))
       (kb:load-plotstyle dbxdoc ps)
       (vlax-put lobj "PlotStyleName" ps)
    ;set linetype
       (setq ln (vlax-get lobjdbx "Linetype"))
       (if (not (tblsearch "ltype" ln))
(setq newln
(vl-catch-all-apply
  'vla-CopyObjects
  (list dbxDoc
(vlax-safearray-fill
  (vlax-make-safearray vlax-vbObject '(0 . 0))
  (list (vla-item (vla-get-linetypes dbxDoc) ln))
  )
(vla-get-linetypes (vla-get-activedocument (vlax-get-acad-object)))
)
  )
       )
)
       (if (tblsearch "ltype" ln)
(vlax-put lobj "Linetype" ln)
)
       )
)
      )
    )
     )
   (kb:CloseDbxDocument dbxdoc)
   (vlax-release-object lstateobj)
   )
    )
