Abstract
Recent investigations show that finite displacement screws form linearly combined sets when they describe incompletely specified displacements of a body. These results are considered in the context of geometric constraints as they are used in computer-aided drawing or design. A constraint — requiring that one or more of the geometric elements point, plane or line, embedded in a body, must remain in coincidence with other such elements which are fixed — is defined by a set of screws which specify all finite displacements which are then available to the body. When so represented, constraints may be manipulated in a manner which is both simple and uniform, and which, for the chosen geometric elements, is linear.
