Detailed Description
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: some limitations exist – Mode with auxilary spine is incompatible with hometetic laws – Mode with auxilary spine and keep contact produce only CO surface.

If <KeepContact> equals BRepFill_Contact: The Normal is defined to achieve that the sweeped section is in contact to the auxiliarySpine. The width of section is constant all along the path. In other words, the auxiliary spine lies on the swept surface, but not necessarily is a boundary of this surface. However, the auxiliary spine has to be close enough to the main spine to provide intersection with any section all along the path.

◆ SetTolerance()
| void BRepOffsetAPI_MakePipeShell::SetTolerance | ( | const Standard_Real | Tol3d = 1.0e-4, |

◆ SetTransitionMode()
| void BRepOffsetAPI_MakePipeShell::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:
- 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.
◆ Simulate()
| void BRepOffsetAPI_MakePipeShell::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.
