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.

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.
