AutoCAD: CAD files slow to opening or slow to regenerating?

August 7, 2014

When working with large files, and electronic files that have been active through many releases of CAD or just a very involved file there may be excess information that is not relevant to the project anymore that could be slowing you down.

Solution:

Purge command offers a quick way to clean out your drawing files of unused, unwanted information.

*Caution: The command Purge should only be used when and if you know the data you are purging will no longer be needed in this drawing or any other drawing file. *Once an item is purged it is removed from that CAD file and is not recoverable. Yes you can recreate the information that was purged but that is now a time consuming factor, especially when blocks are part of the mix.

Purge command is found:

  1. Through the Command Line type in Purge then Enter.
  2. Through the Application Menu select Drawing Utilities then select Purge
  3. Both options bring up the same dialog box.
