Topic: Are there anymore tools to clean a drawing of junk?

[Krushert]

I am getting a coordination drawing from food industry engineer (I don't know what to call them) that bloated with stuff and I have to beat the heck out of it just to get it be usable.  Just by opening and saving the drawing I knock it down from 37 meg to 14 meg.  After hitting it with the following routines I get it down to 12 meg.

copy of delnul.lsp
Delete zero length lines in drawing
QuickClean

The drawing contains a smattering of 3d objects, 2d objects and objects that are 2d but were 3d at one time.   What is also hurting performance is that the drawings is very far from 0,0 but that is due to this being a huge plant for some reason way before this project they pick the lower left corner of the property as the 0,0 for all cad files.  So I have to live with that.

Is there anything that I can throw at?

[M-dub]

layer filters likely have something to do with the file size, too...

Have a look at this thread, counts.lsp may illuminate the nature of the rubbish.

Ok, now run the 'AnalyzeThis' code in this post (let's find out what makes up that model space count of 68050).

[Krushert]

MP I remember you throwing up the two routines Counts and AnalyzeThis.  So I hit it with the AnalyzeThis also for your benefit.  I don't what it all means except that it counts all stuff in a file.  What I suppose to do with it or how it helps me that I do not know.

Already ahead of you.    See above post.

Have you tried AECTOACAD or exporting it to 2007?  Both basically do the same thing - they strip out all of the AEC junk and turn those "special" objects into blocks and plines... basic AutoCAD entities.

Give it a whirl!

[MP]

Well ... what stands out to me are these 2 block definitions:

        A$C33915B18.Count = 800
        A$C460E5761.Count = 513

These are created by CopyClip / PasteClip activities. Seems a pretty high entity count for copy/paste clips.

In model space there are 94 block instances. If said instances are predominantly either of the 2 above your drawing would be rather, ummm, portly.

Knowing your drawing does it seem reasonable that there would be 94 block instances?

Do you know what the majority of those block instances are?

I could pen something to do yet another analysis to examine the block reference distribution but I'd pretty much be fired for working on your stuff rather than my boss' stuff. If the problem remains unanswered by this weekend I'll code something up then. </shrug>

Interesting.  Exported it and then open the file and peform a quick save.

file size 12,809 kb = Before exporting the
file size 11,339 kb = after exporting but before opening the file
file size 12,557 kb = opening and saving the file

I bet my Arch Desktop put the AEC back into the exported file.

Using quick select to Filter for block names, I get the following.  See attached image. 

[Krushert]

Deleted the paper space tab and stuff in that tab.  Reduce the file by less than a 1/10th of meg.

The other thing  I noticed with the blocks is that I can only see and touch 3 blocks with the name fork_truck but the counts is stating that there are 94.  Am I reading info from the counts correctly?

I window selected everything in model space and came back with following from the properties pallet.  It is showing 5 less items than the counts report is showing

MP If you want to pen something for something just to mess around - go ahead.  however by comparing what I can select and what your routines came up I don't think there is going to be much savings.  That being said if that little bit will save time on massive time it takes to regen and open/closing of the file than that would be greatly appreciated.

Background
this file and 6 others all get xref to coordination file and when opening that file I have to close all other files or it will crash Acad with a run time error.    Just in opening the file I have enough time to; go to the loo, get a cup of tea and BS the way there and back.

Thanks MP and Guys

Here is something that will count the inserts of blocks.

Code: [Select]

(defun c:CountBlockInserts (/ EntData tempEnt tempData InsCntList)
   
    (while (setq EntData (tblnext "block" (not EntData)))
        (setq tempEnt (tblobjname "block" (cdr (assoc 2 EntData))))
        (setq tempData (entget tempEnt))
        (setq tempData (entget (cdr (assoc 330 tempData))))
        (if (setq tempData (member '(102 . "{BLKREFS")  tempData))
            (setq InsCntList (cons (cons (cdr (assoc 2 EntData)) (- (length tempData) 2)) InsCntList))
        )
    )
    (foreach i InsCntList
        (print i)
    )
    (princ)
)
