class OffsetCurve from PGeom inherits Curve from PGeom
---Purpose :
-- This class implements the basis services for an offset curve
-- in 3D space.

Create returns mutable OffsetCurve from PGeom;
---Purpose: Creates an OffsetCurve with default values.
---Level: Internal
Create (
aBasisCurve : Curve from PGeom;
aOffsetValue : Real from Standard;
aOffsetDirection : Dir from gp)
returns mutable OffsetCurve from PGeom;
---Purpose : <aBasisCurve> is the basis curve, <aOffsetValue>
-- is the distance between <me> and the basis curve at
-- any point. <aOffsetDirection> defines the fixed
-- reference direction (offset direction).
---Level: Internal
BasisCurve (me : mutable; aBasisCurve : Curve from PGeom);
---Purpose: Set the field basisCurve with <aBasisCurve>.
---Level: Internal
BasisCurve (me) returns Curve from PGeom;
---Purpose : The basis curve can be an offset curve.
---Level: Internal
OffsetDirection (me : mutable; aOffsetDirection : Dir from gp);
---Purpose : Set the value of the field offsetDirection with
-- <aOffsetDirection>.
---Level: Internal
OffsetDirection (me) returns Dir from gp;
---Purpose : Returns the direction of offset.
---Level: Internal
OffsetValue (me : mutable; aOffsetValue : Real from Standard);
---Purpose : Set the field offsetValue with <aOffsetValue>.
---Level: Internal
