package BRepOffset
---Purpose:
uses

TopAbs,

is
enumeration Type is
Concave,
Convex,
Tangent,
FreeBoundary,
Other
end Type;
enumeration Mode is
Skin,
Pipe,
RectoVerso
end Mode;
---Purpose:
-- Lists the offset modes. These are the following:
-- - BRepOffset_Skin which describes the offset along
-- the surface of a solid, used to obtain a manifold topological space,
-- - BRepOffset_Pipe which describes the offset of a
-- curve, used to obtain a pre-surface,
-- - BRepOffset_RectoVerso which describes the offset
-- of a given surface shell along both sides of the surface.
enumeration Status is
---Purpose: status of an offset face
-- Good :
-- Reversed : e.g. Offset > Radius of a cylinder
-- Degenerated : e.g. Offset = Radius of a cylinder
-- Unknown : e.g. for a Beziersurf
Good,
Reversed,
Degenerated,
Unknown
end Status;
enumeration Error is
NoError,
OffsetSurfaceFailed,
UnCorrectClosingFace,
ExtentFaceFailed,
RadiusEqualOffset,
UnknownError
end Error;

---Purpose: This class compute elemenary offset surface.
-- Evaluate the offset generated :
-- 1 - from a face.
-- 2 - from an edge.
-- 3 - from a vertex.

Status : out Status from BRepOffset)
---Purpose: returns the Offset surface computed from the
-- surface <Surface> at an OffsetDistance <Offset>.
--
-- If possible, this method returns the real type of
-- the surface ( e.g. An Offset of a plane is a plane).
--
-- If no particular case is detected, the returned
-- surface will have the Type Geom_OffsetSurface.
