Modify Xref list

my line of thining was the following

Get list of Xref names with "*_ELC" at the end

For each Xref in list

get Insertion Point

insert first new xref at Insertion Point

insert second new xref at Insertion Point

With the function vla-put-path would take care of all and using codes much better than using commands as you are planning to.

but wont that only work with an Xref that already exists in my drawing?

insert first new xref at Insertion Point

insert second new xref at Insertion Point

Can you explain these two phrases a little bit more ?

for example

XREF_1_ELC and XREF_2_ELC exist in my drawing .

they will be replaced with 2 Xrefs each

XREF_1_ELC_Sub_1 & Xref_1_ELC_Sub_2

XREF_2_ELC_Sub_1 & Xref_2_ELC_Sub_2

These must be inserted at the same Insertion Point as the original XREF

for example

 

XREF_1_ELC and XREF_2_ELC exist in my drawing .

 

they will be replaced with 2 Xrefs each

 

XREF_1_ELC_Sub_1 & Xref_1_ELC_Sub_2

 

XREF_2_ELC_Sub_1 & Xref_2_ELC_Sub_2

 

These must be inserted at the same Insertion Point as the original XREF

So did you or were you able to test the program that I posted in post No# 14 ?

no, I didn't test it because that will only replace the existing Xref, and will not insert the second xref

no, I didn't test it because that will only replace the existing Xref, and will not insert the second xref

You are wrong , as I said before after running the program you need to save and close and open the drawing again to see the changes .

(defun c:test (/ lst fnd pth)
 ;; Tharwat 23.06.2015 ;;
 (setq lst '(([color=red]"Xref_1_ELC"[/color] [color=blue]"Xref_1_ELC_Sub1"[/color]) ([color=red]"Old"[/color] [color=blue]"New"[/color])))
 (vlax-for blk (vla-get-blocks (vla-get-activedocument (vlax-get-acad-object)))
   (if (and (= :vlax-true (vla-get-isxref blk))
            (setq fnd (assoc (vla-get-name blk) lst))
            (setq pth (findfile (strcat (cadr fnd) ".dwg")))
       )
     (vla-put-path blk pth)
   )
 )
 (princ)
)(vl-load-com)

"Xref_1_ELC" needs to be replaced by 2 Xrefs"Xref_1_ELC_Sub1" and "Xref_1_ELC_Sub_2"

on a side note:

adding (vla-reload blk) to the end of the code would probably avoid having to save and reopen the drawing to see the Change

by the way I do really appreciate your assistance on this!

(defun c:findxref ( / idx ins sel td xrf xrn )
   (while (setq td (tblnext "block" (not td)))
       (and (= (logand (cdr (assoc 70 td)) 4) 4)
            (wcmatch (setq xrn (strcase (cdr (assoc 2 td)))) "*_ELC") ;; Must pass this criteria before being added to the list
            (setq xrf (vl-list* "," xrn xrf))
       )
   )
   (if (setq sel (ssget "_X" (list '(0 . "INSERT") (cons 2 (apply 'strcat (cdr xrf))))))
       (progn
           (repeat (setq idx (sslength sel))
               (setq ins (cons (cadr (assoc 10 (entget (ssname sel (setq idx (1- idx)))))) ins))
           )
           (print ins)
       )
       (princ "\nNo xrefs found.")
   )
   (princ)
)

was able to solve my problem using the code from Lee Mac by making the following modifications which gave the Name and the Insertion Point. Then while in the Repat funtion I was able to add my xrefs using the Insertion Point and delete the original.

(defun c:findxref ( / idx ins sel td xrf xrn [color=red]Xrn2 xrefN[/color][color=red] Path[/color])
 [color=red](setq pfad "C:/XXXX/Xrefs/")[/color]
    (while (setq td (tblnext "block" (not td)))
       (and (= (logand (cdr (assoc 70 td)) 4) 4)
             (wcmatch (setq xrn (strcase (cdr (assoc 2 td)))) "*_ELC") ;; Must pass this criteria before being added to the list
             (setq xrf (vl-list* "," xrn xrf))
        )
    )
    (if (setq sel (ssget "_X" (list '(0 . "INSERT") (cons 2 (apply 'strcat (cdr xrf))))))
        (progn
            (repeat (setq idx (sslength sel))
                [color=red](setq ins (cadr (assoc 10 (entget (ssname sel (setq idx (1- idx)))))))[/color]
               [color=red](setq xrn2 (cdr (assoc 2 (entget (ssname sel idx)))))[/color]
[color=#ff0000]                (print (strcat xrn2 " at " (rtos x)))[/color]
[color=#ff0000]        (setq xrefn (vl-string-subst "_ELC_Sub1.dwg" "_ELC" (strcase xrn2)))[/color]
[color=red]       (if (findfile (strcat pfad xrefn)) (command "_.-XREF" "_overlay" (strcat pfad xrefn) (strcat (rtos x) ",0,0") "1" "1" "0"))[/color]
[color=#ff0000](setq xrefn (vl-string-subst "_ELC_Sub2.dwg" "_ELC" (strcase xrn2)))
[color=red]       (if (findfile (strcat pfad xrefn)) (command "_.-XREF" "_overlay" (strcat pfad xrefn) (strcat (rtos x) ",0,0") "1" "1" "0"))[/color][/color]
[color=#ff0000][/color]
            )
            
        )
        (princ "\nNo xrefs found.")
    )
    (princ)
)

Probably not the most eloquent method but it achieves the purpose!!

Thanks again for all your help Tharwat and Lee!
