My grouping LISP no longer works, HELP!

[pete592]

I have been using a LISP routine to simulate the old 'group' commands in AutoCAD Mechanical 2012.

This program has worked flawlessly for SEVEN STRAIGHT YEARS, including my current install of AutoCAD.

Suddenly and mysteriously, it has stopped working.  The program starts normally, asking the user to select the objects to group, then appears to complete normally, but the selected objects are not grouped.

Other users in my office on the same CAD version can use this program with the expected results.  The problem is limited only to my installation.  I have tried compete reboots of both AutoCAD and my entire system, but to no avail.

Is there a system variable that could be causing this? Or anything else that may come to mind?

Thanks,

Pete

Here is the LISP code...

(defun c:mgrp ( / ss)
   (princ "\nSelect object to group: ")
   (if (setq ss (ssget))
      (command "-group" "_create" "*" "" ss "")
   )
   (princ)
)

(defun c:dgrp ( / ent gname)
   (if (setq ent (car (entsel "\nSelect group to ungroup: ")))
      (if (and (gnames ent) (setq gname (nth 0 (gnames ent))))
         (command "-group" "explode" gname)
         (princ "\nSelected object is not a member of a group.")
      )
   )
   (princ)
)

(defun gnames (ename / key dct rtn)
   (setq key (cons 340 ename)
         dct (dictsearch (namedobjdict) "acad_group"))
   (while (setq dct (member (assoc 3 dct) dct))
      (if (member key (entget (cdadr dct)))
         (setq rtn (cons (cdar dct) rtn))
      )
      (setq dct (cddr dct))
   )
   (reverse rtn)
)
(princ)

CTRL+SHIFT+A or manually set PICKSTYLE back, does it work now? Your lisp doesn't check or address it if it is turned off.

EXCELLENT.  Thank you so much!

I'm going to read up on PICKSTYLE.  You're probably amazed I'm not the least bit familiar with it.

[pendean]

it's hard keeping track all of them: edit your Lisp to always turn it on if that was the cure.

I will. 

Thanks again!
