The Intelligent Dimensioning of Working Drawing for B-rep based Mechanical Components |
| |
| Abstract: | Based on modeling and feature-based modelling technology, the interment dimensioning of workingdrawing for mechanical components is discussed in a systematic way, and a synthetical model of dimensioninghas been established. In the model the redundancy analysis of dimensioning is doen firstly. Then the combina with ADN-based automatic recognizition of design features and dimensional chain technique is used toform the dimensioning scheme. Thitdly, the CBR(case-base reasioning) method iS used to make mangementfor dimensions automatically in the views of components. Finally,the working drawing of mechanical components is output through Auto CAD software. |
