// Class Description:

//
|
|
// Model for physical volumes. It describes a physical volume and its
|
|
// daughters to any desired depth. Note: the "sought depth" is
|
|
// specified in the modeling parameters.
|
|
//
|
|
// For access to base class information, e.g., modeling parameters,
|
|
// use GetModelingParameters() inherited from G4VModel. See Class
|

// Description of the base class G4VModel.
