add a prefix

[k005]

There are text objects in the form of xxx m². and on the 'TABANALANI' layer... how can we prefix them with a prefix like Kln :?

* There are other text objects that belong to the 'TABANALANI' layer. they have the prefix "Alan". The transaction will not cover it.

Thankyou

I guess thats prefix the string of the text objects? "Kln : 132.00  m²" ?

Does that mean you want those replaced? suffix "Alan" to "Kln :" ?

Hello my friend, how are you?

We will not handle text objects with a field prefix. We will only add a KLN : prefix to text objects without a field prefix. ( TABANALANI Layer )

All good, thank you for asking 🙂

(defun c:demo ( / ss i str)
(if
  (setq	ss (ssget 
		  '((0 . "TEXT") (8 . "TABANALANI")
		    (1 . "#*# m²"));<-- only with leading number values
	   )
  )
  (repeat (setq i (sslength ss))
    (setq str (cdr (assoc 1 (setq ent (entget (ssname ss (setq i (1- i))))))))
    (entmod (subst (cons 1 (strcat "KLN : " str))(assoc 1 ent) ent))
    )
  )
  (princ)
)
