We describe algorithms for computing least-squares best-fit geometric elements to data/ The elements considered are lines, planes, circles, spheres, cylinders and cones. The algorithms employ stable parametrizations of the elements and are based on sound mathematical and numerical principles. They should be of value to the manufacturers and users of coordinate measurement systems.
