This paper presents a new hierarchical lattice space model and a new coordinate measuring support system with a graphic interface based on the model. The 2.5-dimensional model, named Enhanced Z-map model, has a tree structure of component patches such as a Quadtree model and its depth-ended terminal patches represented in the form of Z-map model as a set of z coordinate value of a point according to an X-Y lattice point. The model structure has a theoretical capability to represent a free-form surface by any fine patch unit. The measuring support system has functions to determine the points to be measured on a designed shape and to make a collision-free measuring path by means of the Inverse Offset method. The system configuration inclusive of a 3-dimensional coordinate measuring machine is illustrated and the procedures of supporting functions are explained too. The experimental results of model handling support the promising efficiency of memory compression and the fast processing speed compared with that in a Z-map model. Through the measuring experiments in primitive shapes, it is concluded that the operability to command instructions is improved with the use of a graphic interface based on the model.
