Certain custom Autolisp Routines quit working in AutoCAD 2025 error: no function definition: acet-ui-message

[Sean.Boseman]

Hello, I've been using a couple custom lisp routines for several years now that appear to not work in AutoCAD 2025, yet they've worked in all previous versions. I have both 2024 and 2025 installed and the routines still work perfectly on 2024, but in 2025 I receive the message "error: no function definition: acet-ui-message". Will ask you whether you want to plot to the printer and if so, ask how many copies and will proceed to print to our particular printer. If you say no, it will just change the current drawing's plot settings to our desired settings. Does anyone one know why all of a sudden the long used lisp routine stopped working for AutoCAD 2025? is this just a bug? See below copy of the program, I've also attached the file. I appreciate the help in advance.

(defun c:isg (/ a k qty)
(setq k (acet-ui-message "Do you really want to print a color copy to the ISG Printer?" "Print Confirmation:" 52))
(if (= k 6)
(progn
(setq qty nil)
(setq qty (getreal "\nEnter number of copies <1>:"))
(if (= qty nil) (setq qty 1))
(setvar "cmdecho" 0)
(setq a (getvar "tilemode"))
(while (/= qty 0)
(progn
(if (= a 0)
(command "-plot" "y" "" "\\\\print\\SALES_KM_C558" "11x17" "inches" "landscape" "no" "extents" "fit" "center" "no" "" "yes" "no" "no" "no" "no" "yes" "yes")
(command "-plot" "y" "" "\\\\print\\SALES_KM_C558" "11x17" "inches" "landscape" "no" "extents" "fit" "center" "no" "" "yes" "as" "no" "yes" "yes")
)
(command)
(setq qty (- qty 1))
)
)
)
(progn
(setvar "cmdecho" 0)
(setq a (getvar "tilemode"))
(if (= a 0)
(command "-plot" "y" "" "\\\\print\\SALES_KM_C558" "11x17" "inches" "landscape" "no" "extents" "fit" "center" "no" "" "yes" "no" "no" "no" "no" "yes" "no")
(command "-plot" "y" "" "\\\\print\\SALES_KM_C558" "11x17" "inches" "landscape" "no" "extents" "fit" "center" "no" "" "yes" "as" "no" "yes" "no")
)
(command)

)
(princ)

acet-ui-message is an Express Tools function that displays a message box.

Perhaps check if you have Express Tool installed for 2025?

[Sean.Boseman]

Express Tool does appear to be installed for 2025.

try running a couple of Express tools (start to finish), if they work fine, try your LISP again.

[Sean.Boseman]

Wow, that seems to work! Any idea why I have to run an express tool for the routine to work? I've never had that happen before in subsequent AutoCAD versions. Is this some sort of glitch with 2025?

The value appeared to be already set to 3.

it seems so. add this expression (load "acetutil") at the beginning of your code.

[Sean.Boseman]

excellent, that worked! Thank you!

AutoCAD 2025 does not preload express tools automatically anymore. They wanted to speed up the application startup. So now there is a new function. It works similarly to vl-load-com.

(acet-load-expresstools)

I've tried inserting that expression before and after the (DEFUN C:XD (/ bl blst ent ans).  There are indentions shown in the attached. Are you able to tell me exactly where to insert the expression? Thanks!

(load "acetutil")
(DEFUN C:XD (/ bl blst ent ans)
(setq bl (entsel))
(setq blst (entget (car bl)))
(setq ent (cdr (assoc 0 blst)))
(if (= ent "INSERT")
(progn
(setq xname (cdr (assoc 2 blst)))
(CHKREF)
(if (= check_val 1)

Use the other tip

Seems to work here.

[komondormrex]

you can put it any place outside any function. but very top is likely to be the best place.

thou did not find any et function in your code.
