Detailed Description
Describes functions to build a loft. This is a shell or a solid passing through a set of sections in a given sequence. Usually sections are wires, but the first and the last sections may be vertices (punctual sections).
Constructor & Destructor Documentation
| BRepOffsetAPI_ThruSections::BRepOffsetAPI_ThruSections | ( | const Standard_Boolean | isSolid = Standard_False, |
| const Standard_Boolean | ruled = Standard_False, |
||
| const Standard_Real | pres3d = 1.0e-06 |
||
| ) |
Initializes an algorithm for building a shell or a solid passing through a set of sections, where:
- isSolid is set to true if the construction algorithm is required to build a solid or to false if it is required to build a shell (the default value),
- ruled is set to true if the faces generated between the edges of two consecutive wires are ruled surfaces or to false (the default value) if they are smoothed out by approximation,
- pres3d defines the precision criterion used by the approximation algorithm; the default value is 1.0e-6. Use AddWire and AddVertex to define the successive sections of the shell or solid to be built.
Member Function Documentation
| void BRepOffsetAPI_ThruSections::AddVertex | ( | const TopoDS_Vertex & | aVertex | ) |
Adds the vertex Vertex (punctual section) to the set of sections through which the shell or solid is built. A vertex may be added to the set of sections only as first or last section. At least one wire must be added to the set of sections by the method AddWire. Use the Build function to construct the shape.
| void BRepOffsetAPI_ThruSections::AddWire | ( | const TopoDS_Wire & | wire | ) |
Adds the wire wire to the set of sections through which the shell or solid is built. Use the Build function to construct the shape.
