Rule Name: Nested Primitive Geometry

Definition

When a Primitive Geometry contains a Union of Primitive Geometry for nesting reasons, the resulting geometry must be coplanar. Only Polygon, Ellipse, Line, Arc, and Point Primitive Geometries can have nesting, except for Elliptic Cylinder with Finite Element Mesh (see below).

The possible combinations at any level of nesting are:

• Polygon can nest:
  Polygon, Ellipse, Line, Arc, Point, and Finite Element Mesh

• Ellipse can nest:
  Polygon, Ellipse, Line, Arc, Point, and Finite Element Mesh

• Line can nest Line, Arc, and Point

• Arc can nest Line, Arc, and Point

• Point can nest Point

• Elliptic Cylinder can nest Elliptic Cylinder

• Elliptic Cylinder can nest:
  Finite Element Mesh as an interior 3-D mesh

• Finite Element Mesh cannot nest.

Rationale

When a Primitive Geometry contains a Union of Primitive Geometry for nesting reasons, the relationship means that the union represents a "subface" of the Primitive Geometry, i.e., it is part of the Primitive Geometry.
