Auto-m8

AutoM8 - Batch process drawings with Change, Plot or Purge.
System requirements: Runs inside AutoCAD versions 2000 through 2011.
Computers are really good at replicating our mistakes, especially when drawings are created from other drawings.

You can make changes to drawings where repetitive errors have occurred, whether you need to change some drawing notes, insert new or revised blocks, do an attribute data extraction, zoom limits or extents, create saved views, make layer changes, move, create, erase or copy objects.
