AUTO-BLOCK Improvement

If you have 100 of polylines...then select all object at once

                                                    Should  create 100 of block individually

This will make a block of anything selected but only one entity per block. the old macro was picking point 0,0 as the block point. this will give each selection a unique point. currently set to the lower left of the boundary box of the entity. you can change it to UR or MPT depending on what you want. had to put a delay in because the (Set_BlkName) runs off the time and it would generated the same name and caused errors. you could possibly make it lower so this runs faster.

(defun C:AB1 (/ ss i blk obj LL UR)
  (setq ss (ssget))
  (setq i 0)
  (setvar 'cmdecho 0)
  (command "_undo" "be")
    (repeat (sslength ss)
    (command "_.delay" 100)
    (Set_BlkName)
    (setq obj (vlax-ename->vla-object (setq blk (ssname ss i))))
    (vla-getboundingbox obj 'minpt 'maxpt)
    (setq
      LL (vlax-safearray->list minpt) ;lower left point
      UR (vlax-safearray->list maxpt) ;upper right point
    )
    ;(setq MPT (polar LL (angle LL UR) (/ (distance LL UR) 2))) ;midpoint of bounding box
    
    (command "-block" blkname "none" LL blk "")
    (command "-insert" blkname "none" LL 1 1 0)
    ;(prompt (strcat "\n   Block [" blkname "] Created. ")) ;alot of spam if enambled
    (setq i (1+ i))
  )
  (command "_undo" "e")
  (setvar 'cmdecho 1)
  (setq i (rtos i 2 0))
  (prompt (strcat "\n " i " Blocks Created. ")) 
  (princ)
);end C:AB1

--edit--

added undo marks

misspelling

got  ; error: no function definition: SET_BLKNAME

 

You asked to improve the lisp. What i posted is to replace the original AB1 function lines 41 - 52 in AUTO-BLOCK.LSP.

This is what AUTO-BLOCK.LSP should look like after you replace the original AB1 Function with the one i came up with.

Now selecting any entities with the new AB1 command will create that number of blocks automatically as shown below. Again be careful of what you select because anything will become a block. 6 poly lines and 3 text will become 9 individual blocks.
