Add attributes to BLOCK in LISP with ENTMAKE

I get error while adding an attribute to a block using ENTMAKE "attdef".

What am I doing wrong ?

;makes a block and inserts to drawing
(defun C:test_blk()
(setq x 4 y 4)
(setq ot 0.3 )
(if (= ct nil) (setq ct 1))  
(setvar "CMDECHO" 0)
 (and
   (not (tblsearch "BLOCK"
   (setq blk_nm (strcat "SP" (rtos ct 2 2)))))
   (entmake (list (cons 0 "BLOCK")
             (cons 2 blk_nm)
             (list 10 0 0 0)
             (cons 70 0)))

 (entmake (list (cons 0 "ENDBLK")(cons 8 "0"))))
 (setq blk_rh (entlast))
 (while (eq blk_rh (entlast))
        (command "_.INSERT" blk_nm))


 (setq ct (+ ct 1))

 );defun

It woks fine.

Can you paste the error reply please ?

Regards

Look into group 70 of the BLOCK header call. The 2 bit should be set if variable attributes follow.

Also, a decimal is an invalid block name character. ( rtos ct 2 2 ) includes a decimal.

Those are for starters at least. -David

After the block is inserted in dwg I type "ATTEDIT" and select the block - there are no attributes to edit.

Command: attedit

Select block reference: That block has no editable attributes.

Thanks David - most of the code is from your post in the SWAMP.

fixed entmake block :

(cons 70 2)

Still have to get the attributes working.

Code below seems to work but it isn't satisfactory.

The ENTMAKE attdef code 3 asks for keyboard input while I want it to be a variable generated in LISP (a counter).

Is it possible with ENTMAKE or do I have to look for another solution?

(defun c:test_blk ()

(setq x 4 y 4)
(setq ot 0.3 )
(if (= ct nil) (setq ct 1))  


 ;BLOCK Header definition:

 ;BLOCK's ending definition:

   (command "_.INSERT" blk_nm)

try this

(entmake 
  (list

     (cons 8 0)
     etc...
     (cons 3 [i]variable[/i]);variable should be string
     etc.

This should perhaps point you in the right direction:

(defun GenerateBlock ( name pt )

 (if (not (tblsearch "BLOCK" name))
   (progn
     (entmake
       (list
         (cons 0 "BLOCK")
         (cons 2 name)
         (cons 70 2)
         (cons 10 '(0. 0. 0.))
       )
     )
     (entmake
       (list
         (cons 0 "POINT")
         (cons 8 "0")
         (cons 10 '(0. 0. 0.))
       )
     )
     (entmake
       (list
         (cons 0 "3DFACE")
         (cons 10 '(0. 0. 0.))
         (cons 11 '(4. 0. 0.))
         (cons 12 '(4. 4. 0.))
         (cons 13 '(0. 4. 0.))
       )
     )     
     (entmake
       (list
         (cons 0 "ATTDEF")
         (cons 8 "0")
         (cons 10 '(0.3 4.3 0.0))

     )
     (entmake
       (list
         (cons 0 "ENDBLK")
         (cons 8 "0")
       )
     )
   )
 )

Thanks Lee,

I will try it.
