block object insertion point?

[Glen Smith]

I'm trying to modify a LISP that Lee MAc Wrote for me a couple weeks ago, I'm using it to insert a block at the same insertion point as the existing block. Lee's code uses an excell spread sheet as input for a list of blocks to find in the drawing. Since the code already finds each block, I figure it ought to be able to insert the new block as well. I just can't figure out how to code the insertion point without making the user click it.

(defun c:BLOCKINSERT (/ file nl lst Minp Maxp pts elst ipt)
  (vl-load-com)
  (if (setq file
             (getfiled "Select Text File"
                       (if *load
                         *load
                         ""
                       )
                       "txt"
                       8
             )
      )
    (progn
      (setq *load file
            file  (open file "r")
      )
      (while (setq nl (read-line file))
        ;(princ nl)
        (setq lst (cons (car (StrBrk nl 9)) lst))
      )
      (close file)
      (princ "\n<< Closed file >>")
      (if (setq elst (vl-remove-if
                       'null
                       (mapcar 'handent
                               (mapcar
                                 (function
                                   (lambda (x)
                                     (substr x 2)
                                   )
                                 )
                                 (reverse lst)
                               )
                       )
                     )
          )
        (foreach Obj (mapcar 'vlax-ename->vla-object elst)
 
          (vla-getBoundingBox Obj 'Minp 'Maxp)
          (setq pts (mapcar 'vlax-safearray->list (list Minp Maxp)))
          (vla-ZoomCenter
            (vlax-get-acad-object)
            (vlax-3D-point
              (polar (car pts)
                     (apply 'angle pts)
                     (/ (apply 'distance pts) 2.)
              )
            )
            400.
          )
          (setq ipt (assoc 10 entget (Obj))) 
         (command "-insert" "KEY_MG_RED" ipt 1 1 0)
        )
      )
    )
    (princ "\n<< No File Selected >>")
  )
  (princ)
)
(defun StrBrk (str chrc / pos lst)
  (while (setq pos (vl-string-position chrc str))
    (setq lst (cons (substr str 1 pos) lst)
          str (substr str (+ pos 2))
    )
  )
  (reverse (cons str lst))
)

Can anyone point me in the right direction?

          (setq ipt (assoc 10 entget (Obj))) 
         (command "-insert" "KEY_MG_RED" ipt 1 1 0)

the above code should be

 (setq ipt (cdr(assoc 10 (entget (Obj)))))
         (command "-insert" "KEY_MG_RED" ipt 1 1 0)

if the Obj entity hasn't came out of a selection set the line would be

 (setq ipt (cdr(assoc 10 (entget(car (Obj))))))
          (command "-insert" "KEY_MG_RED" ipt 1 1 0)

Hope that helps

Using the first of the two, I get the error:
Command: ; error: bad function: #<VLA-OBJECT IAcadBlockReference 0be2eabc>


Using the second, I get:
Command: ; error: bad function: #<VLA-OBJECT IAcadBlockReference 0be2eabc>

I don't think that the obj entity came from a selection set, although I'm not entirely sure.

Thanks,

Obj is a VLA-Object represented as a symbol, through the foreach function.

i.e.

(foreach Obj ...

[Lee Mac]

...Lee's code uses an excell spread sheet...

I hope not!... I coded it for a txt file..

[Glen Smith]

Whoops, true, I just use Excel to modify the txt file so much that I forget that they are not the same.

I know you have posted a source for explaining VLA functions in the past, but my searching has been in vain. Would you be so kind as to repost it? I have also read that you have a LISP FAQ that is "coming soon" is it available yet?

Thanks,
Glen

[Lee Mac]

Obviously there are a good few sites to explain the VL functions, here are a few to look at:

http://www.afralisp.net/

VL method differences

Attributes in VL

Paperspace/Modelspace Objects

As for the LISP FAQ, this needs to be approved by the other members before being opened to the public, and this approval is taking some time it seems.
