All hatch patterns are constructed using lines but hatch patterns are inserted as a single drawing object. There are many predefined hatch patterns including ANSI standards, ISO standards, and a solid fill pattern that are part of AutoCAD’s software. The first method works well most of the time but for more complicated drawings, the second method must be used.
The first method is picking an internal point and allow the HATCH command to find an enclosed boundary and the second method involves using an existing closed polyline to define the hatching boundary. It allows you to select two different methods of selecting the boundary of the area to be filled in with the hatch pattern. The HATCH command is used to insert hatch patterns. There are many uses for hatch patterns on a drawing including displaying an object’s material type, the solid material that was cut through in the sectional view, difference materials used in one area to another, plus many other applications. This is called crosshatchingor just hatching.
Many drawings require areas to be filled with a pattern. When you have completed this module, you will be able to:
