Hatch patterns are vector patterns that are made up of diverse combinations of horizontal, vertical, or diagonal lines.
hatching, also called cross-hatching, technique used by draftsmen, engravers, and other artists who use mediums that do not allow blending (e.g., pen and ink) to indicate shading, modeling, and light and shade.
Click Tools > Options > System Options > Area Hatch/Fill to configure Area Hatch/Fill options. When adding an area hatch or fill pattern to a drawing, specify the following attributes. When editing an area hatch or fill pattern in a design, specify the following properties.
To generate darker values on the opposite side of your light source, press slightly harder with your pencil. Working your way to the darkest region of the drawing, build up layers of shade. The core shadow is the deepest of your shadows. On the other side of the light source, rounded forms will have reflected shadows.
