Change ALL dimensions to another existing dimension style?

[ILoveMadoka]

ronjon did this in vlisp HERE

 

I was wanting to do something similar using regular lisp (to incorporate into a larger existing routine...) - I can maneuver a bit better in regular lisp being a novice too

I was hoping that this would work

 

(defun c:test ()
  (if (setq T3 (ssget "_X" '((0 . "DIMENSION"))))
    (repeat (setq n (sslength T3))
      (setq tdata (entget (ssname T3 (setq n (1- n)))))
      (entmod (subst '(3 . "NewDimStyle") (assoc 7 tdata) tdata)) ;;;NewDimStyle exists
    )
  )
(princ))

 

I changed an existing dimension style using the property manager and the only thing that seemed to change was Assoc 3 - ie: (3 . OldDimStyle) 

 

My code does not work for me...

 

Is this a simple fix?

 

I found this in another post somewhere but did not know if you could mix vlisp/"regular" lisp (and don't know how)

 

(vla-put-Activedimstyle (vla-get-activedocument 
                          (vlax-get-acad-object)) 
                            (vla-item (vla-get-dimstyles 
                              (vla-get-activedocument 
                                 (vlax-get-acad-object))) "Name_dimstyle"))

Because it is going into another routine, I wanted to keep it as compact as possible..

Should this be a 3 for the assoc and not a 7?

(entmod (subst '(3 . "NewDimStyle") (assoc 7 tdata) tdata))

 

to be

 

(entmod (subst '(3 . "NewDimStyle") (assoc 3 tdata) tdata))

Dang! I was so close!!

 

You are my hero!!

..and Thank you!!

Close - the 2 parts have to match:

I personally hate it when someone has the same issue as me then posts "I fixed it!" and doesn't post their code...

 

Here is the final code:

 

(defun c:test ()
  (if (setq T3 (ssget "_X" '((0 . "DIMENSION")))) ; finds ALL dimensions
    (repeat (setq n (sslength T3))
      (setq tdata (entget (ssname T3 (setq n (1- n)))))
      (entmod (subst '(3 . "NewDimStyle") (assoc 3 tdata) tdata)) ;;;Assumes NewDimStyle exists / replaces the old Dimstyle with the new
    )
  )
(princ))

Thank you again Steven.

Thanks ILoveMadoka, hoping in this case that the discussion was clear - but a finished code makes the thread even better!!

 

 

It get's worse of course, people who post and asked a question in a single thread only and then delete their account so you can't ask them for a finished code later,

I walked away with not only my end goal met but I learned something as well...
