| Abstract: |
| Based on Dbase Ⅲ database management, this paper describes the techniques by which the parametric databases are designed for mechanical part and assembly drawings. In the paper,the part drawings are constructed by 20 kinds of two-dimensional primitive patterns, and the node coordinates of part drawings are represented by mathematical representations which are functions of part parameters. The assembly drawings are step-by-step assemblage of part drawings.There is small amount of work using this method of the paper. |
