What Program Made a .DWG/.PLT?

Hi all,

Is there a way to determine the program that was used to generate a .dwg &
..plt file?

Also, if Acad was used to create the .dwg or .plt, can I find out what
version was used?


Simon.

 

If you use the Drawing Batch Converter, load the files, it will tell you
what file format of autocad the file is in. Also you can load a drawing
file into Word and the first characters will be something like AC1018, which
means 2004 file format. The 18 corresponds to the release number for 2004,
since the format hasn't changed for 2005 then drawings made in 2005 will
show that number also.

Can't help with plot files.

Hi Kent,

I get AC1015 which I guess is Acad 2000/02?

The reason I asked is that when I wblock and purge out files from
consultants, they get bigger by 300% even though I'm stripping out info! I
thought it might be because they are using another program to generate acad
compatible files... but perhaps not unless those progs generate the "AC10xx"
number automatically.

Simon.

 

Hi
AC1015 is Acad2000 format files, which spans from 2000 to 2002, which you
guessed.

Make sure isavepercent is set to 0, and make sure you are saving to 2004
format and not 2000. I did that early on and couldn't figure out why my
files were getting larger.

Hope that helps, good luck.
Kent

 

Thanks, Kent. isavepercent is set to 0, and I'm using Acad 02 & it's saving
in that format.

Still not sure why the bloat, however. I've exploded the odd attribute or
block here and there, but mostly that stuff gets stripped out. I just
wblocked 5 small exploded attributes (text, circle, line) and the dwg weighs
2.5 mb after purging!

Also go to the autodesk web site and check this out.

http://usa.autodesk.com/adsk/servlet/ps/item?siteID=123112&id=2886521&linkID=2475323

The knowledge base is a good place for anyone to check when having problems
with autocad.

The Delete Layer Filters did the trick! Used a free LFD.lsp and got rid of
27,995 filters!?! That reduced a 4.1 meg file down to 200k(!) after Purge
All. Also deleted dupes which also knocked off a couple hundred K.

Thanks very much Dean and Kent.

 

Also, is there a Standard set of filters included w/acad that I can reimport
to a dwg so I don't need to set them up from scratch? I have the originals
dwgs before using LFD.lsp to delete them, but sorting through 28,000 filters
is a little tedious...

Simon.

 

I posted a method in either the 2004 or 2005 section with the past week or
so. You define the layer filters you want in a txt file which is easy to
modify.

 

Hi Warren,

I downloaded your MakeLayerFilter.lsp on the Acad Customization newsgroup.
However, after loading it I can't get it to run. I've tried "MAKEFILTER"
"MAKEFLTR" and "GATHERFILTER" but those don't work. What is the proper
command?

Simon.

=========

 

Open the lsp file and see what it says right after defun c:
that will tell you what to type once the file is loaded.

 

Does the program load?

It is looking for a specific location for the txt file. Change to match
where you want it to be.

 

Hi Warren,

I have the .lsp file and the .txt file in the same location in the Support
folder path. Is this correct?

Simon.

 

Hi Walt,

The .lsp file says:

(defun GatherFilter (/ FP FL FILENAME)
;; swap next two lines if absolute location is desired.
(setq FP (open "C:/WLT/LIBRARY/FILTERS.TXT" "r") ; file in path
; (setq FP (open "FILTERS.TXT" "r") ; file in path


But "GatherFilter" returns "unknown command" in the command line.
Also, I'm not sure what (/ FP FL FILENAME) means exactly however.


Simon.

 

Back to your original question - the proper command is "gatherfilter".
However, this is ridiculously long for a name. I would have renamed it
"GF" (without the quotes of course) and saved it as GF.LSP. Then, when I
loaded it, I would have typed the following: (load "gf")

However, I cannot make it work as I get an "error on input".

Now, the lsp routine is trying to find FILTER.TXT which should be
located in C:\WLT\LIBRARY

And, unless I have gone completely nuts this monday am, I believe you
should have backslashes instead of forward slashes - but I'm not sure.
Too early.

 

I have a shortcut MF for make filter. I keep the long names in a file to
better describe the function.

Two backslashes = one forward slash.

Change the location to one you desire. I work with a base subdirectory of
"\WLT" so that I put all of my stuff in one location at work.

 

Even if they are in the support path it probably will not work if you do not
change the location in the program as it is hard coded to "C:/WLT/LIBRARY"

Also the "filters.txt" file is an example to show the format.

 

(/ FP FL FILENAME) -- makes the variables local.

 

Thanks Walt and Warren for your help, now I understand
I'll alter the subdirectory today and see how that works.

Simon.

 

My shortcut to do this:

(defun C:MF () (nl15 GATHERFILTER "MAKELAYERFILTER")(GatherFilter))

nl15 is just a function to look in a specific directory, GATHERFILTER is the
command name to check if loaded, "MAKELAYERFILTER" is the file to load, and
(GatherFilter) runs the funtion MF.

This could be rewritten:
(defun C:MF () (if (not GATHERFILTER) (load
"MAKELAYERFILTER"))(GatherFilter))

This assumes that the file is in the path.

I path as I have 6 directories with routines and do not want all in the
support path as some dirs have 1500+ files.
