[ff3d-users] How to extract three boundary of a cylinder?

[Robert Li]

Dear Stephane Del Pino,

  It seems that we can only use whole boundary(on
surface or on <x,y,z> ) of an object, XYZ(min,max)
boundary of structured3d mesh, and plane boundary(I
think it does not work perfectly to extract plane of
an object).
  How to extract three boundary of a cylinder(two
circle area and one cylinder area)? 

Robert
