The problem of solving sets of coupled geometric constraints in the context of inetractive computer aided sketching is studied. Some criteria for solution methods are given and the applicability of a relaxation method is discussed. Despite its relatively slow convergence, the relaxation method turns out to be sufficiently flexible (it works for a variety of constraint types and it can be implemented to handle both under-and over-constrained systems in a stable way) to be of at least qualitative use in an interactive design environment. Some mathematical aspects of the method are discussed and examples of applications are given.
