Hi, 

I am a beginner and I had a problem about sorting.

I had many block with attributes "SORT_ORDER" and "NUMBER"

 

what i want to do is :

1. Select all block in a list

(setq lst1 (ssget "x" '((8 . "layer"))))

2. sort list by attributes "SORT_ORDER"

(no idea)

3.apply new number by lst1 form 001 to 100 into attributes (3 digit).

Because we need to change the number many many time but the number must in order.

 

such as

block format:("SORT_ORDER"== "NUMBER")

(1==001), (2== 002), (3== 003), (4== 004), (5== 005), (6== 006), (7== 007)

we want to del 3

(1== 001), (2==002), (4== 003), (5== 004), (6== 005), (7== 006)

and add back 3 and add 2.1 between b and c

(1== 001), (2== 002, (2.1== 003), (3== 004), (4== 005), (5== 006), (6== 007), (7== 008)

TEST-LSP FOR NUMBING2.dwg

thanks for the reply.

 

and here is what i am doing yesterday.

  

(defun C:nm ( / sel1 sel2 )

	(setq num 0)
	(setq lop 0)

	(setq sel1 (ssget "x" '((8 . "NUMBERING")))) 

	(foreach pp1 (ssnamex sel1)
	(setq num (1+ num))
	)			

	(foreach pp (ssnamex sel1)	
					(setq sel2 (ssname sel1 lop))			   
					(setq a (entnext sel2))
					(setq b (entnext a))
					(setq c (entget b))		
					(setq d (assoc 1 c))					
					(setq e (cdr d))			
					(setq num (1- num))
					(setq lop (1+ lop))
					(setq a1 (cons e a1))
	)	;foreach
	(vl-sort a1 '<)

);end defun

try this 

(defun C:nm (/ ss i blk atts lst a1 P O)
  (vl-load-com)
  (setq ss (ssget '((0 . "INSERT") (8 . "NUMBERING"))))  ;only select blocks on numbering layer
  (repeat (setq i (sslength ss))
    (setq blk (vlax-ename->vla-object (ssname SS (setq i (1- i))))
          atts (vlax-safearray->list (vlax-variant-value (vla-getattributes blk)))
    )
    (foreach x atts
      (if (= (vla-get-tagstring x) "PORT_NUMBER")
        (setq P (vla-get-textstring x))
        (setq O (vla-get-textstring x))
      )
    )
    (setq lst (list P O)) ;create a mini list
    (setq a1 (append a1 (list lst))) ;join all mini lists into big list
  )  
  (vl-sort a1 '(lambda (x y) (< (car x) (car y)))) ;sort by first item in the mini list
)

3. I don't know what you mean.

May i learn more about "ssget"

I am trying to let the computer know which layer i need and i set a value "E" to keep it,

is it possible, if i change the coding like this? (not working)

The issue is that the ssget filter list is quoted as a literal list, and therefore the symbol 'e' will not be evaluated as a variable to yield the value it has been assigned, but will instead remain as a symbol. To better understand this behaviour, and how to alter the expression to evaluate the variable, you may wish to read my tutorial on The Apostrophe and the Quote Function.

When in doubt I use all filters as cons this supports a variable by name and a value like "abc" or 1. Using '(( takes a little getting use to as per info by Lee.

  

(setq ss (ssget "X" (list (cons 0 "LWPOLYLINE")(cons 8 mylayer) (cons 70 1) )))

(setq ss (ssget "X" (list (cons 0 "LWPOLYLINE")(cons 8 "Design") (cons 70 isClosed) )))
