Abstract: Because it is easy to make mistake and more complex by using commonly used unknown-points algorithm, a new method about how to get coordinates of unknown-points are proposed. Some functions in CAD/CAM software are used to solve this problem, such as size dimensioning, measuring and target catch, etc. A lot of examples are given to introduce the operating step of the methods. Compared with commonly used method, the new method is rather simple, precise and convenient.
