Undo does it all without asking

[sandy.sebastian]

A gentleman in my office was using real-time zoom and suddenly the drawing undid everything that he had worked on in that session of Autocad. No warning. Redo command will not work.

We have had a couple of instances that are just random with no commonality at the moment. We are currently using Map 3D 2005.

The really bad thing is that the bak & sv$ files are nowhere to be found.

Any Suggestions?

I haven't had that happen to me, I'm not sure what might have caused it. but, I do know that the only time that you'll have an sv$ in 2005 is when your program crashes, otherwise they're automatically deleted when you close out. don't know about the bak... did he have his autosave set to decent intervals?

[sandy.sebastian]

Auto save was set to every ten minutes, and he was doing incremental saves of his own.

Your auto save files may still be accessible. They are defaulted to go to a temp folder in your profile and can be difficult to find. to check where the files are to be stored go into the files tab in the settings dialog. the listing under "Automatic Save file Location" will show where they are stored. The files will appear with the drawing file name followed by some other characters and the "sv$" extension.

Back up copies can also be stored here depending on your settings.

Unfortunately, after a detailed search of local machines & servers, we could not locate a file.

I guess what I need to know is if someone else has had this problem, and has a workaround for it.

First off, most of the newer cad programs erase the backup (sv$ or ac$) files once the program is closed, unless it crashes or has to be recovered. I'm not happy about that one either...

Someone in my company has had the same problem, and I have not found how to fix it either. When he went to UNDO, it jumped back about 15, 20 commands, and lots of information was lost. I know that this happens more often with the dimension command, and it will sometimes undo all of the dimensions that were done while inside the DIM subcommand. I have been told that I might need to do a total re-install, that there might be faulty lisp routines being run, but I haven't been able to find anything along those lines that fixes the problem. Sometimes when they go to print, it will close AutoCAD and bring up the overlook email program.

I vaguely remember this happening to me. I think it was happening to me in 2004, and I think the fix was to get the lastest patch, or, upgrade to 2005

i doubt this is in-line with whats going on but i thought id throw it out there...

Is it possible that you have a "bad" lisp that is marking a position and then when you use the undo it is actually going back to that marked position?....just a thought.

[dfouch]

Is it possible that you might have your sticky keys are enabled in windows, or you might be triggering another hot key, ie Ctrl. that would make undo jump to the beginning?

Please see this from the command refference:
Reverses the effect of commands

Command line: undo

Enter the number of operations to undo or [Auto/Control/BEgin/End/Mark/Back]: Enter a positive number, enter an option, or press ENTER to undo a single operation

UNDO displays the command or system variable name on the command line to indicate that you have stepped past the point where the command was used.

You could be entering BE somehow.

[kennet.sjoberg]

Check the UNDOCTL system variable, it may be a reason

1 UNDO is turned on
4 Auto is turned on
16 Zoom and pan operations are grouped as a single action

I do use 21 ( = 1+4+16 )

: ) Happy Computing !
