**Abstract**

This talk presents an overview of the problems involved in solving systems of geometric constraints. A basic overview and history will be given followed by a detailed examination of solving these systems by numerical methods. Other associated problems such as over and under constrained systems as well as fully-constrained but unsolvable systems will also be discussed.
