IfcPlanarBox: public Ifc4x3_rc1::IfcPlanarExtent¶
Definition from ISO/CD 10303-46:1992: A planar box specifies an arbitrary rectangular box and its location in a two dimensional Cartesian coordinate system.
NOTE Corresponding ISO 10303 name: planar_box. Please refer to ISO/IS 10303-46:1994, p. 141 for the final definition of the formal standard.
HISTORY New entity in IFC2x2.
The IfcAxis2Placement positions a local coordinate system for the definition of the rectangle. The origin of this local coordinate system serves as the lower left corner of the rectangular box. NOTE In case of a 3D placement by IfcAxisPlacement3D the IfcPlanarBox is defined within the xy plane of the definition coordinate system.
