Size of a saved DWG file grows unexpectedly.

If your DWG file size increases a lot (compared to the originally opened file) when saved from AutoCAD (2012, 2013 or 2014) - up to multiples of the original size - it is most probably caused be processing of complex linetypes from a DGN file. Aply the DGN Hotfix -

Download - and then run the DGNPURGE command.

Other causes of smaller increases of the DWG file size:

Setting an older version of the DWG file format as the default (e.g. DWG2000 in AutoCAD 2014) - see Options
Processing AEC objects - try the command -EXPORTTOAUTOCAD
Processing other proxy objects - see SAVEFIDELITY
Saving thumbnails in high resolution - lower THUMBSIZE (see the tip 8754)
The incremental save mechanism - see ISAVEPERCENT
Anonymous objects - perform PURGE (or see tip 9553)
The original drawing file is not in the genuine DWG format
