What is hatching in CAD terms?

Hatching in CAD (Computer-Aided Design) refers to the technique of filling an area with patterns, lines, or solid colors to represent different materials, textures, or design elements. It enhances visual clarity and aids in distinguishing various components within a drawing. Hatching is often used in architectural and engineering drawings to indicate sections, elevations, or to provide visual contrast in plans. Different hatch patterns can convey specific information about the materials or functions of the represented areas.
