class SensitiveSegment   from Select3D 
inherits SensitiveEntity from Select3D

	---Purpose: A framework to define sensitive zones along a segment
	--          One gives the 3D start and end point;
	--          the maximum number of 2D boxes given
	--          by this entity may be set by the user
	--          if the projected segment is 
	--          vertical or horizontal, one needs only 1 box. 
	--          for a pi/4 angle -> MaxNumber 2D boxes
