	---Purpose: Returns the draft angle of the  face <F> using the
	--          direction <Direction>.  The  method is valid for :
	--          - Plane  faces,
	--          - Cylindrical or conical faces, when the direction
	--          of the axis of the surface is colinear with the
	--          direction.
	--          Otherwise, the exception DomainError is raised.
