Changing attribute layer and color

I’m in the process of updating nearly 400 blocks. I have to change the layer and override the color of one attribute. My test on the first block failed. It's just been a while and I can't remember what I'm missing.

My attempt for changing the first one:

(progn
(setq e (car (entsel ))
 d (entget e)
 n_e (entnext e)
 n_d (entget n_e)))
 un_d (subst (cons 8 "SYM") (assoc 8 n_d) n_d)
 un_d (append un_d (list un_d (cons 62 141)))
)
(entmod un_d)
(entupd (cdr (assoc 330 un_d)))
)

I've also tried:

(command "_.attsync" "_select" n_e "" )"_Yes")

note: as I step through the block entities I will be testing to insure I've got the right block with:

(and 
(= (cdr (assoc 0 n_d)) "ATTRIB")
(= (cdr (assoc 2 n_d)) "SIZE")
(/= (cdr (assoc 8 n_d)) "SYM")
)

If you only want to change 1 block using name no matter where the block is maybe use block edit, BEDIT this will update all.

I would use VL code its a bit easier using get & put to change stuff.

You should post a dwg with this block.

I'm getting closer to what I need with the code below. If I double click on the block, the attribute layer has been updated. But when I check the block defination it remains unchanged.

The commented out attsyncs didn't resolve the issue.

(progn
(defun get_ents ( ss / ents ss1 l cnt)
 (setq ents (list )
  ss1 ss
  l (sslength ss1)
  cnt  0
 )
 (while (< cnt l)
  (setq ent (ssname ss1 cnt)
   ents (append ents (list ent))
    cnt (1+ cnt)
  )
 )
 ents
)
(setq ss01 (ssget "x" (list (cons 0 "INSERT")))
 ents (get_ents ss01)
)
(foreach line ents
 (setq head_e line
  head_d (entget head_e)
  name (cdr (assoc 2 head_d))
 )
 (if (cdr (assoc 66 head_d))
  (progn
   (setq e (entnext head_e)
    d (entget e)
   )
   (if (and
     (= (cdr (assoc 0 d)) "ATTRIB")
     (= (cdr (assoc 2 d)) "SIZE")
     (/= (cdr (assoc 8 d)) "SYM")
    )
    (progn
     (setq d (subst (cons 8 "SYM")(assoc 8 d) d))
     (entmod d)
     (entupd (cdr (assoc 330 d)))
     (entupd (cdr (last (tblsearch "block" name))))
     ;(command "_attsync" "S" (cdr (last (tblsearch "block" name))) "Y")
     ;(command "_attsync" "S" head_e "Y")
    )
   )
  )
 )
)
)

BIGAL,

I don't have a lot of ex with VL. I have about 400 different blocks that each need to have the same update, so I'm not sure that bedit will work here. But I'll look into it.

Thank you.

I attached a file with three of the blocks that I need to update.

Try the following:

(defun c:fixatts ( / d e i s x )
   (while (setq d (tblnext "block" (null d)))
       (if (= 2 (logand 2 (cdr (assoc 70 d))))
           (progn
               (setq e (tblobjname "block" (cdr (assoc 2 d))))
               (while (setq e (entnext e))
                   (if (and (setq x (entget e))
                            (= "ATTDEF" (cdr (assoc 0 x)))
                            (= "SIZE"   (cdr (assoc 2 x)))
                       )
                       (entmod (cons (cons -1 e) '((8 . "SYM") (62 . 141))))
                   )
               )
           )
       )
   )
   (if (setq s (ssget "_X" '((0 . "INSERT") (66 . 1))))
       (repeat (setq i (sslength s))
           (setq e (entnext (ssname s (setq i (1- i))))
                 x (entget e)
           )
           (while (= "ATTRIB" (cdr (assoc 0 x)))
               (if (= "SIZE"  (cdr (assoc 2 x)))
                   (entmod (cons (cons -1 e) '((8 . "SYM") (62 . 141))))
               )
               (setq e (entnext e)
                     x (entget  e)
               )
           )
       )
   )
   (princ)
)

The second half of the code could be replaced by a call to ATTSYNC, but bear in mind that such a call would cause the properties of all attributes to revert to those defined in the block definition, which may be undesirable.

Brilliant!! Doeseverything I need!

Thank you Sir, you’re awesome!

Excellent to hear - thank you for your compliments!

Thank's a lot for that code you save me from a lot of pain.
