Automatic Hatching

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).

Hatching Rules and Rulesets are similar to Representation Rules and Rulesets. Hatching Styles and Rulesets are stored in RPLBs. Local Hatching Rules can be defined by creating HRULs owned directly by Views. The Local Hatching Rules directly reference Hatching Styles (HSTYL).

The hierarchy of database elements for hatching is similar to the Representation Rules, and allows you to impose company or project drawing standards.

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