Detailed Description
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 :
- Any SHAPE can be added in a COMPOUND.
- Only SOLID can be added in a COMPSOLID.
- Only SHELL, EDGE and VERTEX can be added in a SOLID. EDGE and VERTEX as to be INTERNAL or EXTERNAL.
- Only FACE can be added in a SHELL.
- Only WIRE and VERTEX can be added in a FACE. VERTEX as to be INTERNAL or EXTERNAL.
- Only EDGE can be added in a WIRE.
- Only VERTEX can be added in an EDGE.
- Nothing can be added in a VERTEX.
