Exploding Smart Objects

[CADguy82]

Is there some way to prevent CAD Users from exploding any and all smart objects within a drawing?

2"x4"? If it's internal, then I'd say training, discipline, and
documentation.

Sorry, nothing snappy here to say.

There's no way to redefine the explode command via lisp or anything so that smart objects cannot be exploded?

[kcobabe]

with a little command call undefine. I undefine the xplode command and exhange it with the burst command in the hot keys. More times then not they never now the difference. About the only time you will get a question about it is on a pline.

I think if you make a lisp routine that uses the explode and have a box come up that asks if they are sure they want to do that and the amount of information that will be lost as a result may help as well.

the undefine is not dependable IMO, you can just type .explode to get by that.
I would write a little editor reactor with lisp that watched for the explode command:

This sets up the reactor:
(VLR-EDITOR-REACTOR NIL '((:VLR-commandWillStart . MyCallbackFunction)))

Then the callback function that runs whenever a command ended:
(DEFUN MyCallbackFunction (REACTOR COMMAND_L)
(IF (MEMBER "EXPLODE" COMMAND_L)
(progn
(do whatever here)
)
)
)

I have never written a reactor to cancel a command, look in the customization group a bit for code to filter the items
that will be exploded and cancel the command.
Its even easier as I recall in VBA, the events are just public functions.
The trick in this case might be dealing with theselection set, it might be better to react to commandended or other
options.
Reactors are good because they trap all ways of running a command...
