Large Empty Drawing

[Anonymous]

Been a while since I posted here but have an issue with a large empty drawing. Ran purge, audit, -pu and deleted reg apps. Everything gone from the drawing the file size is still 7.8 mbs. Opened it in a newer version of autocad mechanical and ran zombie killer on the file. Still shows over 200,000 proxy objects in it. Most of which are under AcAdParam as you can see by the attached. Seems to be caring over every time I copy and paste from one dwg to another like a virus making the drawing I copy into grow by 7-8 mbs every time I paste. Anyone have any ideas on how to get rid of these? Need to run it in 2009 since I can't save down from 2018 Mech. Currently running MDT 2009.

Thanks for any help with this.

If you would like to view the file, see atached.

I saw something similar to this about 20 years ago. In that case, the problem was eventually diagnosed as being caused by empty or invisible blocks. Does anything show up in the block drop down list when you use the insert command?

Dlanorh No blocks, -purge all etc Audit and son still 7.8mb.

There is a switch I think its "." for file name when doing new that makes a blank dwg, then I would use something like www.Lee-mac.com Steal.lsp to import layers blocks from another drawing this should essentially make a blank dwg. Or start with Wblock command and pick nothing, in CIV3D answer No to include Map maybe be something similar for Mech.

No, absolutely nothing in the drawing at all. QSELECT says empty also.

What is your value of ISAVEPERCENT?  I recommend setting it to 0, then save and reopen the drawing.  There's no guarantee that it will solve your problem, but it's worth trying.

Some old tricks that still occasionally work:

A) Open a fresh, empty drawing. Insert your problem drawing as a block, explode when inserted. Purge.

B) If your problem is in some newish feature, try saving as  DXF in an older format.

- By the time you get down to R12, anything more intelligent than a line has probably been stripped out.
