The BRepBuilderAPI package provides an Application 0028 //! Programming Interface for the BRep topology data 0029 //! structure. 0030 //! 0031 //! The API is a set of classes aiming to provide: 0032 //! 0033 //! * High level and simple calls for the most common 0034 //! operations. 0035 //! 0036 //! * Keeping an access on the low-level 0037 //! implementation of high-level calls. 0038 //! 0039 //! * Examples of programming of high-level operations 0040 //! from low-level operations. 0041 //! 0042 //! * A complete coverage of modelling: 0043 //! 0044 //! - Creating vertices ,edges, faces, solids. 0045 //! 0046 //! - Sweeping operations. 0047 //! 0048 //! - Boolean operations. 0049 //! 0050 //! - Global properties computation. 0051 //! 0052 //! The API provides classes to build objects: 0053 //! 0054 //! * The constructors of the classes provides the 0055 //! different constructions methods. 0056 //! 0057 //! * The class keeps as fields the different tools 0058 //! used to build the object. 0059 //! 0060 //! * The class provides a casting method to get 0061 //! automatically the result with a function-like 0062 //! call. 0063 //! 0064 //! For example to make a vertex <V> from a point <P> 0065 //! one can write: 0066 //! 0067 //! V = BRepBuilderAPI_MakeVertex(P); 0068 //! 0069 //! or 0070 //! 0071 //! BRepBuilderAPI_MakeVertex MV(P); 0072 //! V = MV.Vertex(); 0073 //! 0074 //! For tolerances a default precision is used which 0075 //! can be changed by the packahe method 0076 //! BRepBuilderAPI::Precision. 0077 //! 0078 //! For error handling the BRepBuilderAPI commands raise only 0079 //! the NotDone error. When Done is false on a command 0080 //! the error description can be asked to the command. 0081 //! 0082 //! In theory the commands can be called with any 0083 //! arguments, argument checking is performed by the 0084 //! command. 0085 class BRepBuilderAPI 0086 { 0087 public: 0088 DEFINE_STANDARD_ALLOC 0089 0090 //! Sets the current plane. 0091 Standard_EXPORT static void Plane(const occ::handle<Geom_Plane>& P); 0092 0093 //! Returns the current plane. 0094 Standard_EXPORT static const occ::handle<Geom_Plane>& Plane(); 0095 0096 //! Sets the default precision. The current Precision 0097 //! is returned. 0098 Standard_EXPORT static void Precision(const double P); 0099 0100 //! Returns the default precision. 0101 Standard_EXPORT static double Precision(); 0102 }; 0103 0104 #endif // _BRepBuilderAPI_HeaderFile
