How To O DWG Prefix In AutoCAD?

Understanding Prefixes in AutoCAD

Prefixes in AutoCAD are characters added before command names that alter the way those commands are executed. Most commonly, they streamline the command input process, allowing users to operate more efficiently within the software. For instance, using an apostrophe (') triggers a command while another command is active, such as '_HELP for help while a command is in motion, whereas a dash (-) activates a non-dialog version of a command, exemplified by _-LAYER.
