This paper has a further study on the key technology called validity maintenance mechanism in semantic feature modeling in order to maintain the intent of designers and satisfy them. the method combines geometry model and semantic feature modeling, setting up new feature representation 、 cell element naming and identification method. in the meantime, a history - independence interactive feature boundary re - evaluation algorithm is presented based on feature editing. moreover, the validity recovery mechanism after invalid feature operation can maintain the original feature model. the above ideas have been realized on hust - caid ( computer aided industry design system developed by harbin university of science and technology ) preliminarily
為了能夠正確地維護設計者的設計意圖和滿足用戶的需求，本文在原有造型的基礎上對語義特徵造型中的關鍵技術即有效性維護機制進行深入的研究，將幾何模型，語義特徵模型結合起來統一進行研究，建立了語義特徵造型在產品模型設計過程中特徵表示方法的新理論、細胞元素命名方法和辨別機制，同時對系統原有特徵編輯過程進行了研究，提出了獨立於歷程樹的特徵邊界重構演算法以及模型操作無效時的有效性恢復方法。 -
