Most drawing files that have been
around your plant for a while, and has been updated by multiple users,
usually contain excessive amounts of unused entities like blocks and layers.
Go ahead and use the PostalCAD PurgeAll command by typing PG at the command
line. This will vaporize all those unnecessary items that make your
file balloon in size. The PostalCAD utility will initiate the AutoCAD
Purge command with an All option, five times, to ensure there are no
entities left un-purged. The command line will show the history of
this action after it occurs.
A typical workroom floor drawing
should be no bigger than 1.5 Mb, after purging. If you have TMS or an APPS
unit, the file size will be a bit larger. 3D work will absolutely be
larger in size by a factor of five or more.
Also beware of manufacturers
drawings being inserted into the drawing file. This would definitely
be classified as excessive geometry and should be re-drawn to show only the
basic shapes, not every little nut and bolt.
