Code to change text height

(setq newht (getreal "\n Enter new text height; "))

(setq name (ssname ss1 0))

(setq newlist (subst conlist oldlist ent))
(entmod newlist)
(setvar "cmdecho" 1)

what's that for?

can you be a little less cryptic in your posts please? We like threads to be useable and searchable

I'm assuming that you are posting this as code for others to use, so I'm moving this thread to the Autolisp Archive forum

Allow me to make a few changes for consideration...

1. declare variables local

2. restore cmdecho value that was set, not just set it to 1

3. use (getdist) in text height prompt so user can pick height

4. Add c: prefix so the parenthesis are not needed to call this function

(defun C:chgtext1 (/ CMDECHO CONLIST ENT NAME NEWHT NEWLIST OLDLIST SS1)
 (setq cmdecho (getvar "cmdecho"))
 (setvar "cmdecho" 0)
 (setq newht (getdist "\n Enter new text height; "))
 (princ "\nSelect text: ")
 (setq ss1 (ssget))
 (setq name (ssname ss1 0))
 (setq ent (entget name))
 (setq oldlist (assoc 40 ent))
 (setq conlist (cons (car oldlist) newht))
 (setq newlist (subst conlist oldlist ent))
 (entmod newlist)
 (setvar "cmdecho" cmdecho)
 (princ)
)

Just to elaborate on RKMcSwain's code, this filters out non-text entities and allows for errors in input:

(defun c:chgtxt  (/ ht ss)
 (vl-load-com)
 (if (and (setq ht (getdist "\nSpecify New Text Height: "))
          (setq ss (ssget '((0 . "*TEXT")))))
     (foreach x (mapcar 'entget
                  (vl-remove-if 'listp
                    (mapcar 'cadr (ssnamex ss))))
       (entmod (subst (cons 40 ht) (assoc 40 x) x))))
 (princ))

is it possible to change all the text height in block?
