Define number of characters in Attribute

Hi

I am hoping I am posting on the correct board.

Does anyone know whether there is a way to limit the amount of text in an attribute (Like datafields in Microstation). I need to limit the amount of text added to a block (say 20 characters per line).

Thanks in advance

are you using the attdef or are you using lisp??? if you are only using the
attdef no you cannot limit the amount of characters but if you plan on using
lisp sure you can...

attribute (Like datafields in Microstation). I need to limit the amount of
text added to a block (say 20 characters per line).

 

Hi

Thanks for your reply.
I am currently using attdef. How would you use the lisp, where would I find out about getting a file to do this, and would it be noticeable for other users in the company as not all users like strange things happening...
Finally will the entities still be attributes, and are they edited in the same manner?
Cheers

well, is it a single attribute you are trying to change???(an existing
block) or are you creating an entire new block... if its an existing block
you coudl setup thing like:

(defun gettxt () (setq ss1 (getstring))(if (> (strlen ss1) 20)(do
this)(gettxt))(princ))(defun ea () (gettxt) (command "-attedit" "n" "n"
"enter block name here" "enter attribute tag here" "" "" ss1)(princ))

find out about getting a file to do this, and would it be noticeable for
other users in the company as not all users like strange things happening...
