Table 6.93 — DRM_Geometry_Face

Property

Description

Class
  • <DRM Geometry Face>

Superclass

Subclass
  • None.

Definition

An instance of this DRM class specifies a significant polygonal area.

The external boundary of a <DRM Geometry Face> instance is specified by its <DRM Geometry Face> component.

Clarifications

1 The <DRM Geometry Edge>s that border the <DRM Geometry Face>.

2 For level 3 topology or higher, any <DRM Geometry Node> instances contained within the boundary of a <DRM Geometry Face> instance have an association relationship with that <DRM Geometry Face> instance to indicate the relationship.

For topology of less than level 3, the association relationship between instances of <DRM Geometry Face> and <DRM Geometry Node> has the same meaning, but data providers are not required to supply the information.

3 The <DRM Geometry Volume>s on the front and/or back sides of the <DRM Geometry Face>, respectively.
