How can layers be controlled in AutoCAD?

Using the LAYER command is a fundamental way to control layers in AutoCAD. This command opens the Layer Properties Manager, which provides users with a comprehensive interface to manage different layers within a drawing. With the LAYER command, you can create new layers, modify existing ones, set layer colors, assign line types, and control visibility by freezing or turning off layers.

This command allows for an efficient workflow, especially in complex drawings that contain numerous layers for varying purposes such as organization, visibility management, and specific design elements. Accessing layer control through the command line is often faster for users who are comfortable with keyboard shortcuts, making it a preferred method among experienced AutoCAD users.

While the other options such as clicking on the layer icon or using the properties panel can indeed manage layers, they may not provide the complete functionality that the LAYER command encompasses. The menu bar option under "Edit" may also not directly lead you to effective layer management as streamlined as the LAYER command does. Understanding the versatility and commands available in AutoCAD is crucial for efficient drawing management and organization.
