class MakePipeShell from BRepOffsetAPI inherits MakeSweep from BRepPrimAPI
|
|
|
|
---Purpose: This class provides for a framework to construct a shell
|
|
-- or a solid along a spine consisting in a wire.
|
|
-- To produce a solid, the initial wire must be closed.
|
|
-- Two approaches are used:
|
|
-- - definition by section
|
|
-- - by a section and a scaling law
|
|
-- - by addition of successive intermediary sections
|
|
-- - definition by sweep mode.
|
|
-- - pseudo-Frenet
|
|
-- - constant
|
|
-- - binormal constant
|
|
-- - normal defined by a surface support
|
|
-- - normal defined by a guiding contour.
|
|
-- The two global approaches can also be combined.
|
|
-- You can also close the surface later in order to form a solid.
|
|
-- Warning: In this version some limitation exist
|
|
-- -- We can add only 1 Section (else Standard_NotImplemented is raised
|
|
-- -- Mode with auxilary spine is incompatible with hometetic laws
|
|
-- -- Mode with auxilary spine and keep contact produce only CO surface.
|
|
-- -- Transition treatement is implemented only with the option <BRepBuilderAPI_Transformed>
|
|
-- Normaly all these limitations have to be deleted in mext version.

-- Methodes to define section(s)
|
|
-- =================================
|
|
---Purpose: Give section to sweep.
|
|
-- Possibilities are :
|
|
-- - Give one or sevral section
|
|
-- - Give one profile and an homotetic law.
|
|
-- - Automatic compute of correspondance beetween spine, and section
|
|
-- on the sweeped shape
|
|
-- - correspondance beetween spine, and section on the sweeped shape
|
|
-- defined by a vertex of the spine
|
|
|
|
-- Option is :
|
|
-- -"WithContact" : The section is translated to be in
|
|
-- contact with the spine
|
|
|
|
-- -"WithCorrection" The section is rotated to have a Normal --
|
|
-- parallel to the trihedron's normal and have tangent
|
|
-- perpendicular to the trihedron's tangent.

---Purpose: Adds the section Profile to this framework. First and last
|
|
-- sections may be punctual, so the shape Profile may be
|
|
-- both wire and vertex. Correspondent point on spine is
|
|
-- computed automatically.
|
|
-- If WithContact is true, the section is translated to be in
|
|
-- contact with the spine.
|
|
-- If WithCorrection is true, the section is rotated to be
|
|
-- orthogonal to the spine?s tangent in the correspondent
|
|
-- point. This option has no sense if the section is punctual
|
|
-- (Profile is of type TopoDS_Vertex).

---Purpose: Sets the transition mode to manage discontinuities on
|
|
-- the swept shape caused by fractures on the spine. The
|
|
-- transition mode can be BRepBuilderAPI_Transformed
|
|
-- (default value), BRepBuilderAPI_RightCorner,
|
|
-- BRepBuilderAPI_RoundCorner:
|
|
-- - RepBuilderAPI_Transformed:
|
|
-- discontinuities are treated by
|
|
-- modification of the sweeping mode. The
|
|
-- pipe is "transformed" at the fractures of
|
|
-- the spine. This mode assumes building a
|
|
-- self-intersected shell.
|
|
-- - BRepBuilderAPI_RightCorner:
|
|
-- discontinuities are treated like right
|
|
-- corner. Two pieces of the pipe
|
|
-- corresponding to two adjacent
|
|
-- segments of the spine are extended
|
|
-- and intersected at a fracture of the spine.
|
|
-- - BRepBuilderAPI_RoundCorner:
|
|
-- discontinuities are treated like round
|
|
-- corner. The corner is treated as rotation
|
|
-- of the profile around an axis which
|
|
-- passes through the point of the spine?s
|
|
-- fracture. This axis is based on cross
|
|
-- product of directions tangent to the
|
|
-- adjacent segments of the spine at their common point.
|
|
-- Warnings
|
|
-- The mode BRepBuilderAPI_RightCorner provides a
|
|
-- valid result if intersection of two pieces of the pipe
|
|
-- (corresponding to two adjacent segments of the spine)
|
|
-- in the neighborhood of the spine?s fracture is
|
|
-- connected and planar. This condition can be violated if
|
|
-- the spine is non-linear in some neighborhood of the
|
|
-- fracture or if the profile was set with a scaling law.
|
|
-- The last mode, BRepBuilderAPI_RoundCorner, will
|
|
-- assuredly provide a good result only if a profile was set
|
|
-- with option WithCorrection = True, i.e. it is strictly
|
|
-- orthogonal to the spine.

---Purpose: Simulates the resulting shape by calculating its

|
-- cross-sections. The spine is devided by this
|
|
-- cross-sections into (NumberOfSection - 1) equal
|
|
-- parts, the number of cross-sections is
|
|
-- NumberOfSection. The cross-sections are wires and

|
-- S can be an edge of the given Spine (see Constructor),

|
|
-- returned by the method FirstShape(), it can also be a
|
|
-- Profile (see method Add()) closest to the beginning or
|
|
-- the end of the Spine.
|
|
-- If S is an edge of the given Spine, then method
|
|
-- Generated() returns a list of generated faces and a list
|
|
-- of edges from a free boundary (if it exists) of the
|
|
-- resulting shell.
|
|
-- If S is an edge of the start shape (see FirstShape()),
|
|
-- method Generated() returns a list of faces generated
|
|
-- along the whole spine from the given edge.
|
|
-- If S is a boundary vertex of the start shape (see
|
|
-- FirstShape()), method Generated() returns a list of
|
|
-- edges from the free boundary of the resulting shell,
|
|
-- generated along the whole spine.
|
|
-- If S is a Profile closest to the beginning of the Spine,
|
|
-- method Generated() returns the start shape, that can
|
|
-- also be obtained by method FirstShape().
|
|
-- If S is a Profile closest to the end of the Spine, method
