Topic: AutoCAD Crashes

[jonesy]

I seem to be having major issues with AutoCAD today.

I have had more than 5 crashes this morning (all different drawings) with similar error messages.

Does anyone know what could be causing the message as shown on the attachment?

Many thanks

You might AUDIT or RECOVER the drawing to solve some problems. Mostly these kind of errors mean there is a database problem.

[jonesy]

Thanks, but I've tried that, and it doesnt seem to make any difference.

The crashes seem to happen randomly, sometimes when moving from one layout to another, other times I am zooming to extents...

I have never known a set of drawings to be so unstable.

This error refers to the drawing's internal database of symbols and
blocks. Something has scrambled the drawing's database (possibly
contributed by fragmentation in the Windows swap file). Depending on how
much corruption has been done to the database, you might try inserting
the corrupted drawing into a new drawing and recovering or you may need
to revert to an earlier saved version or intact backup version.

If this drawing was ever edited in Mechanical Desktop or Architectural
Desktop and then edited in LT, the ADT or MDT objects may not have been
maintained correctly causing drawing corruption.

If LT continues crashing with any drawing, then it's likely unstable and
needs a thorough uninstall and clean reinstall.

Thanks Hedge... Bloody things just crashed again.
I'll go check the link

you might have some luck pulling the data through a MAP query; the process will only bring in valid objects....

This is just a stab in the dark; when you first open AutoCAD, check your variable setting 'Whiparc'.  If it is set to 1, check your 'Viewres'.  If this is at some large number like 10000, you may be having issues regenerating the smoothness of arcs and circles.  Change the 'Viewres' to a lower digit like 1000, or change the variable 'Whiparc' to zero.

Whiparc crashed my computer a ton as well:

Thanks for the suggestion. I've just checked the variable and it is set to 0, I assume that is OK?


This variable, is it persistant between drawings and sessions?

Many thanks

Command Reference >  System Variables > W System Variables > 
WHIPARC
 
 
Type: Integer
Saved in: Registry
Initial value: 0

Controls whether the display of circles and arcs is smooth.

0
 Circles and arcs are not smooth, but rather are displayed as a series of vectors
 
1
 Circles and arcs are smooth, displayed as true circles and arcs
 


Please send us your comment about this page


As it is a REGISTRY value, it would be persistent per machine.

You could also type WHIPARC on the command line ... press enter ... then hit F1 to see what Michael (spawn) posted.

unless of course she has reprogrammed the F1 key, or just ripped it off in frustration.....

Well, looking at the error message more closely, and eliminating some possibly obvious possibilities, Hedgehog is on the right track.  However, with it crashing on several different drawings, I would have to lean toward a corrupted block that is used quite frequently and recently placed within those drawings that are causing the crash  (eHadMultipleReaders) ??.  And where it was mentioned the 'database' being corrupted by contribution of the windows swap file (autocad uses it quite often), this could then be amplified and spread across to other drawings with the same block in it.
I don't have any other suggestions other than what Spawn mentioned:

you might have some luck pulling the data through a MAP query; the process will only bring in valid objects....

That would at least show you what is NOT in the drawing, giving rise to what may be corrupted.  Then you just have to go through the other drawings and delete whatever that is and have it replaced.
Could the corrupted block (or entire drawing) be exploded and therefore eliminate the issue ??  I would sure hate to do that, what a mess that would make.

I certainly don't envy your position and I do appologize, I have no further suggestions for you.

I know this sounds a silly question, but which software has the map query on it? I currently run vanilla 09 and revit.
