What does the "HATCH" command do in AutoCAD?

The "HATCH" command in AutoCAD is specifically designed to fill an area with a pattern or solid fill. This command allows users to create different kinds of hatching patterns within closed boundaries, which can help in representing different materials, and textures, or distinguishing various areas in a drawing. For instance, hatching can be used to indicate concrete, grass, or other materials in architectural plans.

Using "HATCH," a user can select a boundary—such as a polyline or a closed shape—and then apply a hatch pattern or a solid fill to that area. This is crucial for enhancing the visual representation of a drawing, making it easier to interpret and understand the various elements it contains.

The other choices describe functions that are not related to the specific purpose of the "HATCH" command. Measuring distances (the first choice) involves tools such as the dimensioning or measuring commands. Adjusting the view of objects (the third choice) pertains to commands that control the viewport or visual perspective of the drawing. Creating 3D models (the fourth choice) relates to a different set of commands focused on 3D geometry. Therefore, the specific functionality of the "HATCH" command in filling areas makes the second choice the correct one
