In Autocad what is Batch Plotting?

In Batch plotting you can plot more than one layout & model at once. Even you can plot more than one drawing with different layouts & models at once. its very very useful tool.  normally we plot only layouts.

Perform tasks automatically whether it is simply Batch Plot, Batch Purge, Batch Insert, Batch Xrefing, Batch Exporting DXF/DWF, Batch Changing Text/Attributes etc. or more complex tasks, Multi-Batch is the program you need. Basically any command or routine you use in AutoCAD or AutoCAD LT, can be set up to work automatically on thousands of drawings.
