Abstract: This paper presents an algorithm based on the intelligent linkage with the application of parametric CAD in constraint solving.Our algorithm improves the geometric construction and complexity.Furthermore,by integrating with other methods,such as the LIM0 method,geometric transformed method, C-Tree method,numerical method and so on,we can build a complete geometric constraint solving framework which solves the 2D and 3D geometric constraint and can automatically give the construction.We also develop a dynamic geometric intelligent software based on the presented algorithm and the results demonstrate the significant performance.
