org.sikongsphere.ifc.model.schema.resource.topology.entity中IfcTopologicalRepresentationItem的子类

限定符和类型	类和说明
class	IfcClosedShell In the current IFC Release only poly loops (IfcPolyLoop) are defined for bounds of face bound (IfcFaceBound).
class	IfcConnectedFaceSet A connected_face_set is a set of faces such that the domain of faces together with their bounding edges and vertices is connected.
class	IfcEdge An edge is the topological construct corresponding to the connection of two vertices.
class	IfcEdgeCurve An edge curve is a special subtype of edge which has its geometry fully defined.
class	IfcEdgeLoop An edge_loop is a loop with nonzero extent.
class	IfcFace A face is a topological entity of dimensionality 2 corresponding to the intuitive notion of a piece of surface bounded by loops.
class	IfcFaceBound A face bound is a loop which is intended to be used for bounding a face.
class	IfcFaceOuterBound A face outer bound is a special subtype of face bound which carries the additional semantics of defining an outer boundary on the face.
class	IfcFaceSurface A face surface (IfcFaceSurface) is a subtype of face in which the geometry is defined by an associated surface.
class	IfcLoop A loop is a topological entity constructed from a single vertex, or by stringing together connected (oriented) edges, or linear segments beginning and ending at the same vertex.
class	IfcOpenShell An open shell is a shell of the dimensionality 2.
class	IfcOrientedEdge An oriented edge is an edge constructed from another edge and contains a BOOLEAN direction flag to indicate whether or not the orientation of the constructed edge agrees with the orientation of the original edge.
class	IfcPath A path is a topological entity consisting of an ordered collection of oriented edges, such that the edge start vertex of each edge coincides with the edge end of its predecessor.
class	IfcPolyLoop A poly loop is a loop with straight edges bounding a planar region in space.
class	IfcSubedge A subedge is an edge whose domain is a connected portion of the domain of an existing edge.
class	IfcVertex A vertex is the topological construct corresponding to a point.
class	IfcVertexLoop A vertex_loop is a loop of zero genus consisting of a single vertex.
class	IfcVertexPoint A vertex point is a vertex which has its geometry defined as a point.
