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:

Public Member Functions | |
DEFINE_STANDARD_ALLOC | BRepOffsetAPI_MakePipeShell (const TopoDS_Wire &Spine) |
Constructs the shell-generating framework defined by the wire Spine. //! Sets an sweep's mode If no mode are setted, the mode use in MakePipe is used | |
void | SetMode (const Standard_Boolean IsFrenet=Standard_False) |
Sets a Frenet or a CorrectedFrenet trihedron to perform the sweeping If IsFrenet is false, a corrected Frenet trihedron is used. | |
void | SetMode (const gp_Ax2 &Axe) |
Sets a fixed trihedron to perform the sweeping all sections will be parallel. | |
void | SetMode (const gp_Dir &BiNormal) |
Sets a fixed BiNormal direction to perform the -- sweeping. Angular relations beetween the section(s) and <BiNormal> will be constant | |
Standard_Boolean | SetMode (const TopoDS_Shape &SpineSupport) |
Sets support to the spine to define the BiNormal of the trihedron, like the normal to the surfaces. Warning: To be effective, Each edge of the <spine> must have an representaion on one face of<SpineSupport> | |
void | SetMode (const TopoDS_Wire &AuxiliarySpine, const Standard_Boolean CurvilinearEquivalence, const Standard_Boolean KeepContact=Standard_False) |
Sets an auxiliary spine to define the Normal For each Point of the Spine P, an Point Q is evalued on <AuxiliarySpine> If <CurvilinearEquivalence> Q split <AuxiliarySpine> with the same length ratio than P split <Spline>. Else the plan define by P and the tangent to the <Spine> intersect <AuxiliarySpine> in Q. If <KeepContact> the Normal is defined to assume like the sweeped section is in contact to the <AuxiliarySpine> Else the Normal is defined by the vector PQ. //! Give section to sweep. Possibilities are : | |
void | Add (const TopoDS_Shape &Profile, const Standard_Boolean WithContact=Standard_False, const Standard_Boolean WithCorrection=Standard_False) |
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). | |
void | Add (const TopoDS_Shape &Profile, const TopoDS_Vertex &Location, const Standard_Boolean WithContact=Standard_False, const Standard_Boolean WithCorrection=Standard_False) |
Adds the section Profile to this framework. Correspondent point on the spine is given by Location. Warning: To be effective, it is not recommended to combine methods Add and SetLaw. | |
void | SetLaw (const TopoDS_Shape &Profile, const Handle< Law_Function > &L, const Standard_Boolean WithContact=Standard_False, const Standard_Boolean WithCorrection=Standard_False) |
Sets the evolution law defined by the wire Profile with its position (Location, WithContact, WithCorrection are the same options as in methods Add) and a homotetic law defined by the function L. Warning: To be effective, it is not recommended to combine methods Add and SetLaw. | |
void | SetLaw (const TopoDS_Shape &Profile, const Handle< Law_Function > &L, const TopoDS_Vertex &Location, const Standard_Boolean WithContact=Standard_False, const Standard_Boolean WithCorrection=Standard_False) |
Sets the evolution law defined by the wire Profile with its position (Location, WithContact, WithCorrection are the same options as in methods Add) and a homotetic law defined by the function L. Warning: To be effective, it is not recommended to combine methods Add and SetLaw. | |
void | Delete (const TopoDS_Shape &Profile) |
Removes the section Profile from this framework. | |
Standard_Boolean | IsReady () const |
Returns true if this tool object is ready to build the shape, i.e. has a definition for the wire section Profile. | |
BRepBuilderAPI_PipeError | GetStatus () const |
Get a status, when Simulate or Build failed. It can be BRepBuilderAPI_PipeDone, BRepBuilderAPI_PipeNotDone, BRepBuilderAPI_PlaneNotIntersectGuide, BRepBuilderAPI_ImpossibleContact. | |
void | SetTolerance (const Standard_Real Tol3d=1.0e-4, const Standard_Real BoundTol=1.0e-4, const Standard_Real TolAngular=1.0e-2) |
Sets the following tolerance values | |
void | SetTransitionMode (const BRepBuilderAPI_TransitionMode Mode=BRepBuilderAPI_Transformed) |
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: | |
void | Simulate (const Standard_Integer NumberOfSection, TopTools_ListOfShape &Result) |
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 they are returned in the list Result. This gives a rapid preview of the resulting shape, which will be obtained using the settings you have provided. Raises NotDone if <me> it is not Ready | |
virtual void | Build () |
Builds the resulting shape (redefined from MakeShape). | |
Standard_Boolean | MakeSolid () |
Transforms the sweeping Shell in Solid. If a propfile is not closed returns False | |
virtual TopoDS_Shape | FirstShape () |
Returns the TopoDS Shape of the bottom of the sweep. | |
virtual TopoDS_Shape | LastShape () |
Returns the TopoDS Shape of the top of the sweep. | |
virtual const TopTools_ListOfShape & | Generated (const TopoDS_Shape &S) |
Returns a list of new shapes generated from the shape S by the shell-generating algorithm. This function is redefined from BRepOffsetAPI_MakeShape::Generated. S can be an edge of the given Spine (see Constructor), it can be an edge or a boundary vertex of a shape 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 Generated() returns the end shape, that can also be obtained by method LastShape(). |
