sketch-based features
解釋
基於草圖的特徵-
Modeling in current 3d cad softwares such as catia, pro / engineer are mainly based on sketch design. according to the idea of modeling and on the basis of segmenting 3d measured data with feature design intention, this thesis studies the reconstruction methods of model sketch - based feature such as extruded and rotational features in structural part models
當前主流的3dcad軟體如catia 、 pro engineer等在實體建模時主要是基於草圖設計的。本文在特徵數據分割的基礎上，結合正向設計的思路，著重研究結構件中的拉伸、旋轉等基於草圖的特徵模型重建問題。 -
In this dissertatio n, product elements pattern class and geometric feature class are defined, and a product domain knowledge base is built, including product elements pattern rules database, geometric features database, and product template for elements mapping. based on the pattern matching and constraint adding mechanism, the sketch is interpreted and regularized
構建了產品領域知識庫，包括產品元素模式規則庫、產品元素幾何特徵庫和產品模板映射器，定義了產品元素模式類和幾何特徵類，通過一會模式匹配機制和約束施加機制，實現對草圖元素設計層的解釋和規整。
