The bounding box is used to define a cuboid (box) that can contain a described part completely. Therefore, it is a simplified representation of the bounding volume and represents a definition of the maximum volume occupied by the part.
It is valid to use the BoundingBox to describe the dimensions of a component, even if not all dimensions are known (e.g. only length and width). However, it must be possible to transform such a partial bounding box into a complete bounding box by adding the missing dimensions.
Defines the extent of the bounding box in the direction of x (length).
Defines the extent of the bounding box in the direction of y (width).
Defines the extent of the bounding box in the direction of z (height).
Defines the bounding box of the part.
