AutoCAD coordinates

Please help.

I need an AutoCAD VBA routine that can do the following:

1) Pick an existing block to get it's coordinates.

2) Pick another block and put the first block's coordinates into the picked block's attribute with the tag "PT1".

Welcome to CADTutor cabltv1, hope you like it here.

This thread may get more replies in the VBA/AutoLISP customisation forum - see if you can get a moderator to move it for you.

But - DO NOT DUPLICATE this thread in that forum - get this one moved.

The actual request shouldn't be too difficult - I'll see what I can do for ya

Your wish is my command

Cabltv - is this something that you need to do often or is it a one time thing? Sounds to me like it could be done via exporting the coordinates to Excel and ..then...I'm lost...

With this you can do one block after another:

(defun c:attpt (/ pBlk dBlk ptBlk aEnt aEntLst)
 (while (and (setq pBlk (car (entsel "\nSelect Block to Retrieve Coordinates >  ")))
         (setq dBlk (car (entsel "\nSelect Destination Block >  ")))
         (= (cdr (assoc 0 (entget pBlk))) "INSERT" (cdr (assoc 0 (entget dBlk))))
         (= (cdr (assoc 66 (entget dBlk))) 1))
   (setq ptBlk (cdr (assoc 10 (entget pBlk)))
     aEnt (entnext dBlk))
   (while (/= "SEQEND" (cdr (assoc 0 (setq aEntLst (entget aEnt)))))
     (if (= "PT1" (cdr (assoc 2 aEntLst)))
   (progn
   (setq aEntLst (subst (cons 1 (strcat (rtos (car ptBlk) 2 2) ","
                        (rtos (cadr ptBlk) 2 2) ","
                        (rtos (caddr ptBlk) 2 2)))
                (assoc 1 aEntLst) aEntLst))
   (entmod aEntLst)))
     (setq aEnt (entnext aEnt))))
 (command "_regenall")
 (princ))

Thanks Lee.

That did the trick!

No Probs, glad it worked for you

If you have any more questions, just ask

There is one other thing.

It works great but I need the function to stop after picking the second block with the "PT1" attribute without having to hit the escape key.

I'll modify it, but you shouldn't have to hit Esc, just either right-click or hit enter.

Here ya go buddy:

(defun c:attpt (/ pBlk dBlk ptBlk aEnt aEntLst)
 (if (and (setq pBlk (car (entsel "\nSelect Block to Retrieve Coordinates >  ")))
         (setq dBlk (car (entsel "\nSelect Destination Block >  ")))
         (= (cdr (assoc 0 (entget pBlk))) "INSERT" (cdr (assoc 0 (entget dBlk))))
         (= (cdr (assoc 66 (entget dBlk))) 1))
   (progn
   (setq ptBlk (cdr (assoc 10 (entget pBlk)))
     aEnt (entnext dBlk))
   (while (/= "SEQEND" (cdr (assoc 0 (setq aEntLst (entget aEnt)))))
     (if (= "SIZE" (cdr (assoc 2 aEntLst)))
   (progn
   (setq aEntLst (subst (cons 1 (strcat (rtos (car ptBlk) 2 2) ","
                        (rtos (cadr ptBlk) 2 2) ","
                        (rtos (caddr ptBlk) 2 2)))
                (assoc 1 aEntLst) aEntLst))
   (entmod aEntLst)))
     (setq aEnt (entnext aEnt)))
 (command "_regenall")))
 (princ))

Thanks. I really appreciate your effort.

I see your are a "Super Member". What exactly does that mean?
