Which command is used to edit a block reference in AutoCAD?

The "BEDIT" command is specifically designed to edit block definitions in AutoCAD. When you use this command, it allows you to open the Block Editor, where you can make changes to the geometry and properties of the block. This is essential for any user who needs to modify the contents of a block after it has been created, enabling updates to the design without having to recreate the entire block from scratch.

Using the Block Editor is particularly efficient as it provides access to all of the components of the block, allowing for detailed edits and adjustments. After making changes in the Block Editor, you can save them, and every instance of that block throughout the drawing will update automatically. This ensures consistency and saves time during the design process.

Other commands, while useful in their own right, do not specifically focus on editing block definitions in this way; they either perform different types of modifications to objects or change properties without providing a dedicated environment for block manipulation.
