Details #!N #!N The cross section of the tube is an 
 #!F-adobe-times-bold-r-normal--18*   n #!EF -gon in a plane parallel to the normal 
and perpendicular to the tangent at each point on the path, 
where the normals are provided by a "normals" component if present 
or approximated from the path otherwise. Normals to the tube are 
computed and associated with the tube for shading. #!N #!N For
