What is the function of the "HATCH" command in AutoCAD?

The "HATCH" command in AutoCAD is specifically designed to fill an enclosed area with patterns, solid fills, or gradients. This feature is essential for representing different materials, textures, or to visually differentiate various sections within a drawing. When using the "HATCH" command, users select an enclosed region, and the software applies the chosen fill type, making it a powerful tool for enhancing the visual detail and information content of technical drawings. This functionality is critical in fields such as architecture and engineering, where clear representation of different materials or areas is necessary for communication and documentation.
