    摘要: A multi-directional parallel rule 1 for e.g. navigational plotting or draughting comprises an edge 3 of a selected shape, e.g. straight, and a first pair of spaced apart wheels 6 mounted to enable the edge 3 to be moved in a first direction. A second pair of wheels 10 are mounted to enable the edge 3 to be moved in a second direction 18 substantially at right angles to the first direction.
