Hatched Elements
Significant elements (BRAN, EQUI, SUBS and FRMW) are sectioned, not their primitives, and so a Hatch Rule that applies to Sectioned Faces must select on significant elements. If it selects on BOXes or VALVs (say) no hatching is applied.
For example, you can define three Hatching Rules for to a View to apply different hatching patterns to concrete and steel items cut by a section plane, and a different hatching pattern again to the top surfaces of panels representing an escape route.
A Hatch Rule can only be applied to Sectioned Faces or Primitive Surfaces, not both. Only one Hatch Rule can be applied to a Design element. For example, you cannot hatch both types of face of a Design element, and it is not possible to hatch differently the three surfaces of a BOX element that are visible in an isometric View.
