A Builder is used to create Topological Data Structures.It is the root of the Builder class hierarchy.
There are three groups of methods in the Builder :
The Make methods create Shapes.
The Add method includes a Shape in another Shape.
The Remove method removes a Shape from an other Shape.
The methods in Builder are not static. They can be redefined in inherited builders.
This Builder does not provide methods to Make Vertices, Edges, Faces, Shells or Solids. These methods are provided in the inherited Builders as they must provide the geometry.
The Add method check for the following rules :
void TopoDS_Builder::Add | ( | TopoDS_Shape & | S, |
const TopoDS_Shape & | C | ||
) | const |
Add the Shape C in the Shape S. Exceptions.
void TopoDS_Builder::MakeCompound | ( | TopoDS_Compound & | C | ) | const |
Make an empty Compound.
void TopoDS_Builder::MakeCompSolid | ( | TopoDS_CompSolid & | C | ) | const |
Make an empty Composite Solid.

The basic method to make a Shape, used by all the Make methods.
void TopoDS_Builder::MakeShell | ( | TopoDS_Shell & | S | ) | const |
Make an empty Shell.
void TopoDS_Builder::MakeSolid | ( | TopoDS_Solid & | S | ) | const |

void TopoDS_Builder::MakeWire | ( | TopoDS_Wire & | W | ) | const |
Make an empty Wire.
void TopoDS_Builder::Remove | ( | TopoDS_Shape & | S, |
const TopoDS_Shape & | C | ||
) | const |
Remove the Shape C from the Shape S. Exceptions TopoDS_FrozenShape if S is frozen and cannot be modified.
