It is through the use of hatch patterns that you can easily determine at first glance whether the drawing represents a section view or an orthographic view of a part. Of these elements, hatch patterns breathe life into a drawing, helping improve the readability of the drawing. The clarity and readability are pegged on a number of elements, including but not limited to the dimensioning, the views used, line weights, and the use of hatch patterns. A CAD or technical drawing is intended to relay clear design instructions to fabricators, product designers, builders, engineers, architects, students, and all other parties involved.
