ClosureSurface

-- Name -- ClosureSurface

ClosureSurfaces are used for buildings which are not enclosed completely, for example airplane hangars or barns. In order to represent those objects as geometrically closed volume object, the open sides are sealed (virtually closed) by ClosureSurfaces. -- Description -- NOTE: Those special surfaces are taken into account, when needed to compute volumes and are neglected, when they are irrelevant or not appropriate, for example in visualisations.
