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

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 GenerativeComponents interprets these principles. There are some GenerativeComponents specific naming and programming conventions that are essential to using the system effectively.
