Detailed Description

The BRepBuilderAPI package provides an Application Programming Interface for the BRep topology data structure.

The API is a set of classes aiming to provide :

• High level and simple calls for the most common operations.
• Keeping an access on the low-level implementation of high-level calls.
• Examples of programming of high-level operations from low-level operations.
• A complete coverage of modelling :
• Creating vertices ,edges, faces, solids.
• Sweeping operations.
• Boolean operations.
• Global properties computation.

The API provides classes to build objects:

• The constructors of the classes provides the different constructions methods.
• The class keeps as fields the different tools used to build the object.
• The class provides a casting method to get automatically the result with a function-like call.

For example to make a vertex <V> from a point

one can writes :

V = BRepBuilderAPI_MakeVertex(P);

or

BRepBuilderAPI_MakeVertex MV(P); V = MV.Vertex();

For tolerances a default precision is used which can be changed by the packahe method BRepBuilderAPI::Precision.

For error handling the BRepBuilderAPI commands raise only the NotDone error. When Done is false on a command the error description can be asked to the command.

In theory the comands can be called with any arguments, argument checking is performed by the command.
