    I am new to scripting in autocad and am looking to create a script that will reference the Standard Scale attribute of the viewport and use this to scale my text. Is this possible?
    I am use to scripting in Alias Maya and Side Effects Houdini where attributes are easily accessible. Does Autocad work this way at all.

    apprecitate the help and info,

    Hello chris
    this is a modified snippet from one of my programs. It scales all TEXT elements to the hight h*vps*factor, where h is the old text hight, vps is the scale factor of the selcted viewport and *factor* is a constant value wich i set to 1 for default.


    (setq *factor* 1.0)
    (defun c:chtext ( / A B D E F H vp)
    (Setq A (Ssget "x"))
    (Setq B (Sslength A))
    (setq vp (entget (car (entsel "\nSelect viewport: "))))
    (setq C (* (/ (cdr (assoc 41 vp)) (cdr (assoc 45 vp))) *factor*))
    (While (> B 0)
    (Setq B (1- B))
    (Setq D (Ssname A B))
    (Setq D (Entget D))
    (If (= "TEXT" (Cdr (Assoc 0 D)))
    (Setq E (Assoc 40 D))
    (Setq H (* C (cdr E)))
    (Setq F (Cons 40 H))
    (Entmod (Setq D (Subst F E D)))
    (Setq A nil)
    (princ "\ndone")
