.dwg File Growth

Ahoy, CadTutor,

I am a new member to this site. Not new to AutoCad, but not very accomplished.

Some fairly simple files have ballooned to 'large'. Autocad 16

Example: One crept-up from ~~ 3 megs to 12 megs. Saved -w- new name, erased all, purged, and with addition of a single 200" line, is way down to 11.9 megs!!!!!!!?????? That must be a pretty aggressive line.

Any fix? I'd hate to re-draw all, particularly if it may happen again.

Thanks /s/ Bob

Check your blocks for $acd12mhjj etc these are copied and pasted blocks often a block can be a whole dwg hidden away somewhere find it explode delete and purge. At worst wblock out your model space, copy paste/add your paperspace objects one at a time and find the offending object.

What does zoom e do a little dot in each corner ? Offending object will be at 1 of the corners.

Unfortunately as its 12mb you could if happy copy to a drop box and someone may have a look.

My guess is you have an over abundance of linetypes in your drawing that may have been associated with Microstation. Take a look. Do any of the linetype types include the letters DGN?

Sometimes multiple PURGEs are required. Try PURGE > AUDIT > PURGE, save, close and re-open drawing and repeat. Are you running any ACAD addon software that might be adding data/dictionaries to your drawings?

Also have a look here for some usual suspects... https://carefuldrafter.wordpress.com/2014/07/22/reduce-file-size-in-autocad/

The process I recommend is this...

Overkill

-Purge, Regapps

-Purge, All

Audit

Run the above sequence twice saving after the first run through.

If that doesn't do the trick try using the WBLOCK command.
