I am not on my CAD computer at the moment but the first thing I would check for is the presence of a large number of linetypes with the letters DGN somewhere in the name. These would have come from someone incorporating content first created in Microstation.

It looks like all those linetypes are your problem.

 

The screenshot only shows a very small part of the linebloat you are espousing.

Need to open it in Autocad 2015 or newer, or try the linetype bloat tools on the Autodesk site.

 

Carrying a lot of baggage there.

Linetypes! Hey, Dadgad, were they mostly DGN linetypes?

[Dadgad]

I don't see DGN in their names, but there sure are a lot of them.

 

If you look at the screenshot, a fair number of them look surprisingly similar.

Solution:

Run command line:

 

(DICTREMOVE (namedobjdict) "ACAD_DGNLINESTYLECOMP")

 

and

 

_purge

 

Save file, close, open.

maratovich: Are you saying you recognize the linetypes as having come from Microstation?

Maybe. I just can not say.

I only suggest solutions.

[ReMark]

So, in essence, you were offering the suggestion without first determining the facts? Sweet.

[maratovich]

Yes. it is impossible to determine exact problem.

I saved the file to the .dxf.

It opened in notepad.

I found many descriptions DGN lines.

I suppose that the author uses AutoCAD 2013-2014.

Found fix from Autodesk

End.

maratovich did you try the hot fix it did not work for me at the time. (2016 now)

[maratovich]

BIGAL : hot fix only AutoCAD 2013, 2014.

For 2016 - Run command line:

(DICTREMOVE (namedobjdict) "ACAD_DGNLINESTYLECOMP")

and

_purge

Save file, close, open.

[BIGAL]

Thanks maratovich, we are unlucky to get maybe 1 DGN a year.

Nice one, thanks Maratovich!

I just tried that on 2013 Vanilla, and it reduced it to 399k.

[designerstuart]

wow, guys, thanks so much! you've been busy while i was away!
