Abstract :
Geometric constraint solving is an integral part of computer aided design, serving the role both of precisely situating geometric elements in relation to each other, as well as dimensioning and constraining their shapes accurately. We discuss how to solve variational constraint problems involving points, lines and planes. We concentrate on small problems that must be solved simultaneously
