class MakeDraft from BRepOffsetAPI inherits MakeShape from BRepBuilderAPI
---Purpose: Build a draft surface along a wire
-- The wire can be defined by
-- - a wire
-- - a face (the forward wire)
-- - a shell (the free bounds)
-- The Draft geometry is defined by
-- A wire, a direction and angle between the line section
-- and the dircection
-- The Draft can be limited by
-- a length of the segment to sweep
-- a surface
-- a shape
uses
Shape from TopoDS,
Shell from TopoDS,
Dir from gp,
ListOfShape from TopTools,
TransitionMode from BRepBuilderAPI,
Draft from BRepFill,
Surface from Geom

is
Create(Shape : Shape from TopoDS;
Dir : Dir from gp;
Angle : Real)
---Purpose: Constructs the draft surface object defined by the shape
-- Shape, the direction Dir, and the angle Angle.
-- Shape must be a TopoDS_Wire, Topo_DS_Face or
-- TopoDS_Shell with free boundaries.
-- Exceptions
-- Standard_NotDone if Shape is not a TopoDS_Wire,
-- Topo_DS_Face or TopoDS_Shell with free boundaries.

AngleMin : Real = 0.01;
AngleMax : Real = 3.0)
---Purpose: Sets the options of this draft tool.
-- If a transition has to be performed, it can be defined by
-- the mode Style as RightCorner or RoundCorner,
-- RightCorner being a corner defined by a sharp angle,
-- and RoundCorner being a rounded corner.
-- AngleMin is an angular tolerance used to detect
-- whether a transition has to be performed or not.
-- AngleMax sets the maximum value within which a
-- RightCorner transition can be performed.
-- AngleMin and AngleMax are expressed in radians.

---Purpose: Sets the direction of the draft for this object.
-- If IsInternal is true, the draft is internal to the argument
-- Shape used in the constructor.

---Purpose: Performs the draft using the length LengthMax as the
-- maximum length for the corner edge between two draft faces.

---Purpose: Performs the draft up to the surface Surface.
-- If KeepInsideSurface is true, the part of Surface inside
-- the draft is kept in the result.

---Purpose: Performs the draft up to the shape StopShape.
-- If KeepOutSide is true, the part of StopShape which is
-- outside the Draft is kept in the result.

---Purpose: Returns the shell resulting from performance of the
-- draft along the wire.
