Coordinate Dimension – (1) Either of two coordinates that locate a point on a plane and measured its distance from either of two intersecting straight-line axes along a line parallel to the other axis. (2) Any of three coordinates that locate a point in space and measure its distance from any of three intersecting coordinate planes measured to that one of three straight-line axes that is the intersection of the other two planes. Often the application of dimension origin is referred to as a coordinate dimension.
