Topic: Block insert on points

[ronjonp]

So I have a bunch of points in a drawing on about 10 different layers and I want to insert a certain block at each point. The blockname that is inserted corresponds to the layer the point is on. I have the code below that I could duplicate 10 times and it would work but I was wondering what are the different ways to grab all the layers in the drawing in a list and evaluate with selection sets of point objects?

Code: [Select]

(defun c:symbols (/ path ss index obj pt)

(command "._undo" "_begin")

(setq path "C:/GPS_SYM/")

(if (setq ss (ssget "x" '((0 . "POINT")(8 . "FULL_CIRCLE"))))
     (progn
       (setq index -1)
       (while (< (setq index (1+ index)) (sslength ss))
(setq obj  (ssname ss index)
               obj  (vlax-ename->vla-object obj)
       pt   (vlax-get obj 'coordinates)
)
(vl-cmdf "_-insert" (strcat path "FULL_CIRCLE.dwg") pt "" "" "")
       )
     )
   )
(command "._undo" "_end")
)
Thanks,

Ron

Hi Ron,
You can try this, I have not tested it but I believe it will work.....providing the block/layer names match as you described.

Code: [Select]

(defun c:symbols (/ path ss index obj pt layname lay)
  (command "._undo" "_begin")
  (setq path "C:/GPS_SYM/")
  (while (setq lay (tblnext "layer" (not lay)))
    (setq layname (cdr (assoc 2 lay)))
    (if (setq ss (ssget "x" (list '(0 . "POINT") (cons 8 layname))))
      (progn
(setq index -1)
(while (< (setq index (1+ index)) (sslength ss))
  (setq obj (ssname ss index)
obj (vlax-ename->vla-object obj)
pt  (vlax-get obj 'coordinates)
  )
  (if (tblsearch "block" layname)
    (vl-cmdf "_-insert" layname pt "" "" "")
    (vl-cmdf "_-insert"
     (strcat path layname ".dwg")
     pt
     ""
     ""
     ""
    )
  )
)
      )
    )
  )
  (command "._undo" "_end")
)

Thanks Jeff. Exactly what I was looking for.

Here is the code I spawned from Jeff's example above if anyone is interested.

Code: [Select]

(defun c:symbols (/ scl path ss index obj pt layname lay fn AGGH)

      (vla-Get-ActiveDocument

      )
    )

      (vla-Get-ActiveDocument
(vlax-Get-Acad-Object)
      )
    )
    (princ (strcat "\n Undo begin set " (getvar 'dwgname)))
    (princ)
  )

  (defun UndoEnd ()
    (vla-EndUndoMark
      (vla-Get-ActiveDocument
(vlax-Get-Acad-Object)
      )
    )
    (princ (strcat "\n Undo end set " (getvar 'dwgname)))
    (princ)
  )
  (UndoBegin)
  (setq scl (getreal "\n Enter drawing scale: "))
  (setq path
(getfiled "Where are your blocks?"
   (getvar 'dwgprefix)
   "dwg"
   8
)

    (progn
      (while (setq lay (tblnext "layer" (not lay)))
