Finding center of text

Part of the solution might be to use use Express tools "justify text" to change all to middle center. This works without moving the text objects.

Use the TEXTBOX lisp function...

Ah yes I had already tried that but the cht rotation "always" centers it's rotation on the insertion point no matter where the text is justified.

Thanks for the reply, but I don't know of any TEXTBOX lisp function. Is it downloadable somewhere? We are running AutoCad R-14 with Civil Design Softdesk8. We do have Bonus Tools but when I type in TEXTBOX I get "unknown command" .

In the Help files for R14 (text, bounding box, AutoLISP) there is a lisp routine for drawing a box around text:
(defun C:TBOX ( / textent tb ll ur ul lr) (setq textent (car (entsel "\nSelect text: "))) (command "ucs" "Object" textent) (setq tb (textbox (list (cons -1 textent))) ll (car tb) ur (cadr tb) ul (list (car ll) (cadr ur)) lr (list (car ur) (cadr ll)) ) (command "pline" ll lr ur ul "Close") (command "ucs" "p") (princ)
)
Use that; draw the diagonal and rotate the text around the midpoint of the diagonal.
There might be other ways...

Thank you! This will do it I'm sure, just some trig from here.

HiHo; Here is a R14 lisp program and DCL. Hope this helps. ............................................................................ ................

Thank you! I will try this as soon as I get home. Also I wonder if you could help me with my outdated version of VLisp. I'm running the R-14 Version of Cad and Vlisp which I just installed. However when I try to Debug a file all of my Step Into Step Over Step Out are grayed out ? I have the breakpoint set at the first function I have the lsp file loaded and open I've also tried creating a project but the step functions seem hopeless grayed off. Do you know what I am doing wrong ??

Well I figured it out. You have to set the breakpoint "before" you load the file. Seems like "load" should have been "run" to me, but whatever.
