Dwg. size HUGE.....help

[SteelDet]

Using AutoCad 2000 and have drafting dwg's sized at 1600kb, even after purging EVERYTHING..........lol. Usually they're around 300-400kb in size. I've looked for a lisp program and can't seem to find one that works.

Thanks,
Betty

It could be an "unpurgeable" block that isn't being used. But quite possibly is one of many things that don't purge - Layer Filters, Registered Application, Layer States, Unnamed Groups. These can be purged with "cdgpurge". An older version can still be downloaded at http://www.caddepot.com/dcd1/Autodes...s/index-8.html
A likely culprit is Layer Filters. You just need a little lisp to get those. try this:

(princ "\nType LFD to start")
(defun C:LFD ()
(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))

hehe. I was just about to recommend that about the layer filters. It is something how much room that takes up.
