| Abstract: | The feature model presented here is consisted ot five components: solid model, measure elements, size dimensions, and location dimensions as well as constrains behaviour. The PCO (Parent Child Operator) is proposed for capture the dependency between features. A PCG (Parent Child Graph) is presented for the representation of the feature-based parts model. Te algorithm is given for the accessing to PCG. |
