Topic: Drawing with errors, open very slow only in AutoCAD (Bricscad OK)

)Some of the entities ("ACAD_ASSOCPERSSUBENTMANAGER" and "ACAD_PERSUBENTMGR") are proxy entities and cannot be deleted.

In BricsCAD copy-pasting the block in a 'clean' drawing works.
I would try that, and check how this new drawing opens in AutoCAD. Then you will know if it is the block or the dictionary entries that are to blame.

[roy_043]

Wblocking ('Entire drawing') also works.

I have tried Wblock from Bricscad but I get same problem when open the wblocked DWG in AutoCAD... 

[ronjonp]

Try the drawing in this thread.

[Marc'Antonio Alessi]

Try to Google "BlockPurgePreventer":

Code: [Select]

Dynamic blocks
US 7860691 B2
 Estratto
Tools and techniques for creating and editing a master block definition for a dynamic block, and manipulating a block instantiation of a dynamic block are described. One or more data structures that can be used to implement a dynamic block feature are described

[roy_043]

So the block does seem to be the culprit.
Maybe removing the draworder (AcDbSortentsTable) from the block definition will help?

Code - Auto/Visual Lisp: [Select]

1. (vla-delete
2.   (vla-getextensiondictionary
3.     (vla-item
4.       (vla-get-blocks (vla-get-activedocument (vlax-get-acad-object)))
5.       "A$C6E506268"
6.     )
7.   )
8. )

I get nil (Bricscad) then in AutoCAD nothing happen.   

[roy_043]

I get nil (Bricscad) then in AutoCAD nothing happen.   

(vla-delete) always returns nil. So that is to be expected.
If wblocking combined with the removal of the draworder does not work then I can think of only one other solution: SAVEASR12.

Note that wblocking is effective in the sense that the file size is drastically reduced (from 3.3 Mb to 60 Kb).

Thanks again for your time   
1) if I saveasr12 all is ok, but I would not lose some important >R12 features... 
2) if I delete only "A$C6E506268" block, all is OK (open in AutoCAD is normal)
...
9) it is very strange that AutoCAD takes several minutes to open a 80kb DWG! And I can not recover the problem 

[Marc'Antonio Alessi]

News: if I open in AutoCAD (2013) and (after 10 min.) I explode the "A$C6E506268" block AutoCAD hangs for further 10 min... for ever   

[cmwade77]

Have you tried exploding it in BricsCAD, then copy and pasting it into a new drawing in AutoCAD?

ETA: Nevermind, that didn't work either. This one is strange, even more normal cleanup routines for dealing with bricsCAD files aren't fixing this one.

Tested in the full original DWG (where there are other similar block and many other things) I can normally open the DWG in AutoCAD only if the delete fully the block, exploding only not solves. Thanks.

After many tests I was able to isolate the only entity responsible but I could not understand where the problem lies.   
Attached a 50kb dwg with only an hacth that hang AutoCAD:
