Hi all,

I have a major problem with the file I work on in Autocad 2008.

My file has many layouts and I wanted to set up viewport visibility
for each layout separately, so that I could show different contents
on different sheets. To do that I was setting up layer thaw/freeze in
viewports on respective layouts (obvious so far...)

I started playing with freeze/thaw/visible etc, all in layer manager
and that's where I hit a major problem!

Suddenly my computer got crazy with this file, it works EXTREMELY
slowly, it regenerates drawing for couple of minutes now, switching
layouts or sometimes even zooming in/out made it entirely impossible
to work!

Every time I enter/exit viewport, change layout or open the block
editor, CPU hits 100% and stays there for minutes! Status bar says it
is 'Regenrating the model again - buffering viewport' as well as
'Generating 600 (sometimes 1200!) modified elements' - even though I
merely switched layouts!

Computer was able to handle the file perfectly until a few minutes
ago, it's as if he hit a wall or somehting! I can still work with it
say in model space, drafing, hatching etc, as long as I do not change
viewport...

I do not get it but it suddenly made my work almost impossible!!!
PLEASE HELP!! I am moderately experienced user but honestly - have no
clue how to handle that behaviour!

PS. File is in 2D, does not have many xrefs etc, plain lines some
text, hatches, a few references to jpgs, that's it!

Taking a stab here-
try the command "-scalelistedit", including the hyphen, then "?". If you happen to have a whole lot, then "reset".

Hey Carl!

Thanks for the tip - I don't know if it was you, but it seems to be better now!
Question: what have I just reseted? And does this operation apply only to this file or to my Cad profile as well?

I assume when you checked your number of "scale lists" you found a whole bunch, so getting rid if them returned your normal speed. yes you should check your template or other standard drawings to clean them out. Somewhere some drawing contained all these and they get transferred to other drawings.

Problem AUTOCAD 2008 - 100% CPU usage, constant regenerating
