( 3 ) the generation methods of sketch - based feature model reconstruction are presented in this thesis . experimental results show that the methods presented here are reliable ( 3 )研究了基于草圖輪廓的拉伸與旋轉(zhuǎn)特征模型重建的生成方法,以實(shí)例零件說明本文提出的重建方法是切實(shí)可行的。
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(dāng)前主流的3dcad軟件如catia 、 pro engineer等在實(shí)體建模時主要是基于草圖設(shè)計的。本文在特征數(shù)據(jù)分割的基礎(chǔ)上,結(jié)合正向設(shè)計的思路,著重研究結(jié)構(gòu)件中的拉伸、旋轉(zhuǎn)等基于草圖的特征模型重建問題。
