Body Geometry • The hierarchy of geometrical entities – Point > Section > Patch > Component > Assembly. • Each component or assembly is represented by a mesh of rectangular and, occasionally, triangular panels. • Panels are grouped in patches, which are rectangular arrays of panels. • The surface of a model is composed of one or more patches. • A patch may consist of a single panel
