Hi,

I would like to perform a intersection of 2 solids in the TGeomerty
package.


I have defined :

   TGeoVolume *ge_tub =
	gGeoManager->MakeTube("geTube",Ge,0.0,tubeOuterRGe,tubeGeHalfT);


   TGeoVolume *ge_pgon =
	 gGeoManager->MakePgon("gePolygon", Al, 0,360,6,2);
   TGeoPgon   *pgon    = (TGeoPgon*)(ge_pgon->GetShape());
   
   pgon->DefineSection(0,-tubeGeHalfT, 0, rOuterBase);
   pgon->DefineSection(1, tubeGeHalfT, 0, rOuterTop);

	
   The question is : how do I use TGeoIntersection to obtain the same
   result as I have in Geant4 when using 

  G4IntersectionSolid* solidGe = 
    new G4IntersectionSolid("germanium",ge_tub,ge_pgon);



Many thanks,

Karl
