Why are my Acad2000 dwg files so big when they have so little in them?

[FredBear]

My office uses ACAD2000. (kinda old but works for our purposes.)

I have noticed that some drawing files are very large for their
content. One example is a drawing with 8 lines which has 3 layers, no
blocks, and its size is about 3 megabytes.

The drawing is totally purged.

I'm looking for any recommendations. Are there any utilities out
there that can clean up hidden garbage?

Unfortunately my CAD team can't be taught good drawing hygeine.

Thanks in advance.

Try purging the DWG files of Layer Filters. Create the following Layer Filter
LSP file (LFD.lsp), load and run it. Then Save the file and compare it with
the origina (BAK) file. If that works, then I'd suggest that you set up to
run the LFD.lsp file automatically each time you open any file. This way it
will Purge the drawing of Layer Filters all the time.

ps... whatch out for word wrap in the Lisp file cut/paste info that I've
included

Download "SuperPurge" and run it. It will let you "hard purge" anything
(even used layers, dictionaries, etc..).

This will allow you to not only just clean the file but also to find out
what's causing the bloat.

HTH,

Thank you both. SuperPurge, alas was no help. My 8 line drawing is
still at 2.7 meg.

If you want to email me the dwg I'll take a look at it.

HI
I would be interested to hear your comments Michael

I recall a couple of months ago a similar situation
We procuce drawings typically of 200k to 500k bytes in sizes and
superinpose them onto architectural backgrounds. At one time we
created a small note of 5 lines of text on a drawing which was approx
3meg is size and subsequently write blocked the text for future use.
The block file for the text was a little less that the original
drawing but was still close to the 3megs. We tried purging but there
was nothing to purge and the original author of the architural drawing
could not provide us with any help. After disfcussions with several
colleagues we noted that there was a similar situation with just a
single line (instead of the text) and assumed that the original
drawing had some kind of watermark that was transfered to subsequent
changes and gave up. We were using ACAD 2000i and the architect said
that his original drawing was authored on ACAD 2004. We subsequently
made sure that our blocks were on virgin stardard sheets

One thought came to mine. If you have some blocks which are lots of JUNK in
them, you might want to try to clean them up (and redefine them) and see if
that makes a difference. That is one reason why you can't purge some stuff
because they are part of a block.
Unfortunately my CAD team can't be taught good drawing hygeine.

That is something you should deal with. In my humble opinion (having been
drafting manually/CAD for over 30 years)... SLOPPY drafting is NOT excusable.
And if a 'draftperson' doesn't understand the necessisty of clean CAD work,
they read them the riot act.

My 2-Bits worth.

Well, there's lots of reasons for drawing bloat. Blocks, X-Refs, Dim
Styles, Text Styles, Template, Layer Filters, Etc. Etc. can all add bloat.
For instance, I used to use an "add-on" product that ran inside of AutoCAD
(Arch-T) and it would add layers and other info to every file I opened. I
could purge the stuff out but it would come back the next time I opened the
drawing.

I can't give a definitive answer to what you're experiencing without looking
at a problem file.

The offer stands for you too, if you want to send me a "problem" file I'll
take a look at it and let you know what I find.

When drawings become huge compared to their content I use the "wblock"
command, save what the monitor screen shows, and create a new drawing
file. This has always brought huge files dowm to size. The command is
in 2000.
