Both in data structures and in geometry, the concept of dimensionality plays a major role.

OpenBuildings™ GenerativeComponents relies heavily on geometry to capture and express design. Since it is an associative, parametric modeler, geometric primitives are often defined as the result of operations on other pre-existing geometric primitives. Therefore it is essential that these geometric primitives and their associative operations are well understood, as this is the key to successful use of a parametric and associative modeler.

The geometry primer establishes fundamental geometric principles and how OpenBuildings™ GenerativeComponents interprets these principles. There are some OpenBuildings™ GenerativeComponents specific naming and programming conventions that are essential to using the system effectively.
