    Create(X,Y: Real; U1,U2: Real)
    
    	---Purpose: Create an intersection point between 2 parametric 2d lines.
    	--          X,Y are the coordinate of the point. U1 is the parameter
    	--          on the first element, U2 the parameter on the second one.
    
    	returns IntPoint;


    Create(X,Y: Real; U1: Real)
    
    	---Purpose: Create an intersection point between a parametric 2d line,
    	--          and a line given by an implicit equation (ImplicitCurve).
    	--          X,Y are the coordinate of the point. U1 is the parameter
    	--          on the parametric element.

	--          the SetValue method after this one.

    	returns IntPoint;

	---Purpose: Set the values for an "implicit" point.

    ParamOnSecond(me)
    
    	---Purpose: Returns the parameter on the second element.

    	--          is raised.
