CastleIfc

Declaration

type TIfcBoundingBox = class(TIfcGeometricRepresentationItem)

Description

Orthogonal box oriented parallel to the axes of the object coordinate system in which it is defined. It is defined by a Corner being a three-dimensional Cartesian point and three length measures defining the X, Y and Z parameters of the box in the direction of the positive axes.
