Model faces created by section planes, and surfaces of specified Design primitives can be hatched automatically by defining and applying Hatching Rules. The hatching is carried out automatically as part of the Update Design process. Refer to Section Planes for further information.

The Hatching Rules (HRUL elements) define the faces to be hatched, and they reference Hatching Styles (HSTYL elements). Hatching Styles define the styles and colours to be used to draw the hatching. Hatching Rules are stored in Hatching Rulesets (HRST elements).

Hatched areas can be auto-blanked to allow annotation placed on top of them to be legible. Refer to Autoblank for further information.
