Hatch Patterns

Material hatches were traditionally drawn by hand so it was important that each drafter was consistent in how they drew the hatch symbols. However, as we have transitioned to computer design software like AutoCAD and Revit, designers can simply select the hatch from a library and make modifications to the scale, angle, or fill region. Keep in mind that some office have their own standards, but the hatches shown below are very common across the industry.

There are a wide array of hatches used in construction documents, but some of the more common architectural material symbols are shown below.
