class MakePipe from BRepOffsetAPI inherits MakeSweep from BRepPrimAPI
---Purpose: Describes functions to build pipes.
-- A pipe is built a basis shape (called the profile) along
-- a wire (called the spine) by sweeping.
-- The profile must not contain solids.
-- A MakePipe object provides a framework for:
-- - defining the construction of a pipe,
-- - implementing the construction algorithm, and
-- - consulting the result.
-- Warning
-- The MakePipe class implements pipe constructions
-- with G1 continuous spines only.

is
Create( Spine : Wire from TopoDS;
Profile : Shape from TopoDS )
---Purpose: Constructs a pipe by sweeping the shape Profile along
-- the wire Spine.The angle made by the spine with the profile is
-- maintained along the length of the pipe.
-- Warning
-- Spine must be G1 continuous; that is, on the connection
-- vertex of two edges of the wire, the tangent vectors on
-- the left and on the right must have the same direction,
-- though not necessarily the same magnitude.
-- Exceptions
-- Standard_DomainError if the profile is a solid or a
-- composite solid.
