class Curve from ShapeCustom 

	---Purpose: Converts BSpline curve to periodic

uses

    Curve from Geom

is

    Create returns Curve from ShapeCustom;
    
    Create (C: Curve from Geom) returns Curve from ShapeCustom;
    
    Init (me: in out; C: Curve from Geom);
    
    ConvertToPeriodic (me: in out; substitute: Boolean; preci: Real = -1)
    returns Curve from Geom;
        ---Purpose: Tries to convert the Curve to the Periodic form
    	--          Returns the resulting curve
    	--          Works only if the Curve is BSpline and is closed with 
        --          Precision::Confusion()
    	--          Else, or in case of failure, returns a Null Handle
