Interface Shell

Complex, Composite, CompositeSurface, Geometry, OrientablePrimitive, OrientableSurface, Primitive, TransfiniteSet

@UML(identifier="GM_Shell",
     specification=ISO_19107)
public interface Shell
extends CompositeSurface

Represents a single connected component of a solid boundary. A shell consists of a number of references to orientable surfaces connected in a topological cycle (an object whose boundary is empty). Unlike a ring, a Shell's elements have no natural sort order. Like rings, Shells are simple.
