Slow saves

We have several drawings that seem to cause an extremely long lag time
before saving. What I mean by this is that we issue the "save" or
"qsave"
command, and the computer sits for about 20 to 50 seconds (depending
on the
speed of the computer), then it saves the drawing quickly.

The problem doesn't seem to be the computers settings because some
drawings
are fine. Also, if I start with a "good" drawing and copy anything
(even
just a line) from the bad drawing to the good drawing, the good
drawing will
be corrupted and start doing the same thing. Even if I delete the
offending
line, the file is still corrupted. When the entity is copied from the
bad
file to the good file, the good file jumps in size from 24kb to 598kb.

I have recovered, purged, and WBlock-ed the entire drawing (-wblock *)
to no
avail. I have also done these remedies with the files in AutoCAD R14.
Saving in AutoCAD R14 works fine (fast), but the file is still in the
600kb
range, and when opened/saved in 2002, the problem remains.

HELP! Due to the nature of this problem, more and more drawings are
becomming corrupted as users copy entities from one drawing/project to
another.

Systems are running AutoCAD 2002, with Express Tools 1-9, on Win2000.

profile
and custom profiles.

 

How many "named layer filters" are there? They get transferred from
drawing to drawing.
If you have many, try this little routine to delete them all.
;downloaded from AcadX.com, author: R. Robert Bell

(defun C:LayerFiltersDelete ()
(vl-Load-Com)
(vl-Catch-All-Apply
'(lambda ()
(vla-Remove (vla-GetExtensionDictionary
(vla-Get-Layers
(vla-Get-ActiveDocument
(vlax-Get-Acad-Object))))
"ACAD_LAYERFILTERS")))
(princ "\nAll layer filters have been deleted.")
(princ))

(defun C:LFD () (C:LayerFiltersDelete))

Or, if you want to save some of them, use this one.

Tried it. It cleaned up the layer filters, but this had no effect on
the slow save problem. Thanks for trying to help me.

 

If the drawings have a lot of ttf text, that might be the problem.
