protected

Closes the definition of Vertex and Edge Lists Warning : Called only by EndSimpleShell and EndSolid.

void IGESSolid_TopoBuilder::EndLoop ( )

protected

Closes the definition of a Loop and fills it Warning : EndLoop should not be called directly but through SetOuter or AddInner, which work on the current Face.

void IGESSolid_TopoBuilder::EndShell ( )

protected

Closes the definition of the current Shell Warning : EndShell should not be called directly but through EndSimpleShell (for a simple Shell), SetMainShell (for main Shell of a Solid) or AddVoidShell (to a Solid)

	)

Defines an Edge(UV), to be added in the current Loop by EndEdge <edgetype> gives the type of the edge <edge3d> identifies the Edge(3D) used as support The EdgeList is allways the current one <orientation gives the orientation flag It is then necessary to :

give the parametric curves
close the definition of this edge(UV) by EndEdge, else the next call to MakeEdge will erase this one

void IGESSolid_TopoBuilder::MakeFace ( const Handle< IGESData_IGESEntity > & surface )
