Hi everyone..

I'm trying to find out what is the cause..

Thank you.

Drawing contains 3680 anonymous block definitions and 136575 entries in the ACAD_DGNLINESTYLECOMP dictionary.

Try the following:

Code - Auto/Visual Lisp: [Select]

1. (defun c:purgeall nil
2.     (dictremove (namedobjdict) "acad_dgnlinestylecomp")
3.     (command "_.-purge" "_r" "*" "_n")
4.     (repeat 3 (command "_.-purge" "_a" "*" "_n"))
5.     (princ)
6. )

Here's a tool as well.

Here's a tool as well.

That's exactly what I used to diagnose the drawing - a great utility from MP.

That's pretty sweet! Thanks for sharing.

Yup .. I've been using it for years . It's amazing how littered drawings are nowadays.

It's amazing how littered drawings are nowadays.

We do quite a large amount of plat production here and the drawing with the least amount of objects will have the largest file size ever! It's all from doing a "save as" on a drawing that was done a year ago and just reusing it over and over and over... 

Some of our production techs don't even know how to start with a TEMPLATE or how to create a NEW drawing. 

Most of this has been corrected by now but once in a while we'll come across one of those "old balloon" drawings.

Sorry,..my poor English...
I mean,...without this great tool....where do you start for looking at ?
after purge and audit,..what must be the next step to look ?
the fact is that each problem have a solution...but I resolve most of them by a combinaison of "logic" and "deduction" and make test for each steps.
but when I can't found any more steps....how you guys doing to find out what the problem can be ?
search on the net,...ok,...but having the answer do not tell me why this issue is present and how can I found the right direction to look at..
it's like proxy's entities...who we never know wich kind of proxy's are..

maybe I'm not clear again...sorry for that..
thank you.

Doesn't the -exporttoautocad command get rid of all the proxies? Explodes them into simple Autocad entities, I thought.

Any time Autocad tells me there are proxies in a file I'm opening, I use that right away.

Drawing size has to come from somewhere, and not everything is an entity (line, circle, etc.).  A lot of size comes down to data objects, which can be attached to entities or the drawing itself.  The latter is one of the first places I look, checking for various non-standard dictionaries (like AEC and AutoPLANT gunk).

Aside from an obvious abundance of graphical entities, I would simply look for collections (including dictionaries) which contain large numbers of objects - of course, MP's 'Counts' program performs this analysis automatically for you, making it very easy to identify such bloated collections.
