Hello,

I have noticed You have there multiple block references that might not be edited/removed for some reason (maybe because they origin from other AutoCAD product).

If you want to get rid of those, a solution would be to either:

- EXPORTTOAUTOCAD command

- WBLOCK command

Kind Regards,
Pawel

Hi @nadel-b,

I ran through all the usual clean up items such as:

Audit
Purge
-Purge>All
-Purge>Regapps

But, as @swieciakpawel points out, there are some AEC proxy objects in the file. His recommendation of -EXPORTtoAutoCAD got the file done to 99k.

I used the command -EXPORTtoAutoCAD and was OK

Thanks a lot

Hello,

I have one drawing with enormeous size (28MB) even there is only about 1500 entities. I tried the steps above, but the size is almost the same.

Can be other solution for it?

Thanks a lot Kamil

Hi,

I looked at it yesterday and also saw the problem
with a line of code I can also delete the data with one row of code,
but I knew no way "from a user point of view" to solve the problem.

Today I did a test and it works with native commands and the GUI,
how the user usually works.

However: I have not found a way how the user can find out about the problem at all,
that was only possible in other ways.
So I present the solution, but you cannot check in the program beforehand whether this problem exists at all.

Problem: Data from sheet sets / Sheet list tables and other data / perhaps from XRef-binding in the past.
Solution: Create a new table set table of contents, this causes an update of AutoCAD which deletes the obsolete data.
Then you can delete the table of contents.

Add one layout to a sheet set and insert a sheet list table to your Layout.

(You are familiar with sheet sets and Sheet list tables? -> SheetListTable[F1])

That's all, you can delete the new sheet list now.

Hello,

thanks for the answer. I understand the reason of the big size now but I undestand that remowing the unused data from the drawing is not possible by normal AutoCAD commands.

Can you send me the code you using to delete it? We have NET/LISP application and the clearing of the data can be part of it.

Thanks a lot Kamil

"Can you send me the code you using to delete it?"

It's nothing i saved

If i would save such single lines, the time for searching is much longer then searching the problem and re-writing it again.

And: I am in Holliday, without AutoCAD.

Sorry.
