You might want to try min_extent and max_extent to define the 
contained_by box (can also be a sphere)

Help 3.3.1.6.5 Functions

min_extent(OBJECT_IDENTIFIER), max_extent(OBJECT_IDENTIFIER). The 
min_extent and max_extent return the minimum and maximum coordinates of 
a #declared object's bounding box (Corner1 and Corner2), in effect 
allowing you to find the dimensions and location of the object.

Note: This is not perfect, in some cases (such as CSG intersections and 
differences or isosurfaces) the bounding box does not represent the 
actual dimensions of the object.

I do not understand why you show this
Unless it is an example of this:
