Accuracy. The closeness of agreement between a measured or computed value and the theoretically true value of the object being measured or modeled. In 3D CAD systems, accuracy may refer to closeness with which a 3D model edge or surface intersection approximates its theoretically true value. Analytic Representation. A geometric entity capable of being represented by an algebraic expression in precise form. Angle. The degree of rotation of either of two intersecting lines, a line and a surface, or two intersecting surfaces necessary to produce coincidence with the other, the rotation being in the plane of the lines and about the point of intersection. 57
