Dear Jerome,

Your request is a little unclear, so please excuse if I reiterate some 
basic concepts, which are key to creating a geometry.  If this does not 
answer your question, please provide further information, and we will 
try to do this.

- The solid is the shape of a volume, and it can be a box, a polycone or 
a boolean solid (the result of an operation between two other solids.)

- Only when you have a solid can you create a logical volume, which add 
a material, visualisation properties (optional), a field (optional) and 
other attributes.

- A physical volume represents one (or a set of) these logical volumes 
which has/have been placed each in a particular location.

So the two concepts and classes, physical volumes (including 
parameterised volumes) and solids, are completely separate.  You cannot 
use a parameterised volume (which is a type of physical volume) as one 
part of a solid. It is the wrong type.

If you could explain further what you want to achieve, it could be 
possible to suggest how to implement it. 

Best regards,
John Apostolakis
