Aha ! Maybe I need to delve deeper into what could be done using the
"Bounds" and "BoundingLeaf". Just curious if you don't mind....

Would it be possible to use the Bounds knob to restrict the range
of the clip plane in the 2 directions other than the half-space
direction ? I have held the notion that using the ModelClip planes
it will be possible, for example, to cut out a small square solid
piece from within a larger square plate and display the small solid piece,
but not the contrary - that is, display the large square plate
with a hole cut into it. If the latter is indeed possible, that
gives me some ideas to try out :)...Please confirm.

Thanks and Regards
