sketch n. 1.草图,粗样,略图;素描,速写;草稿。 2.概略,大意,大要,纲领。 3.短篇作品,小品文〔如特写、随笔、见闻录等〕。 4.(滑稽)短剧;独幕剧;短曲、短小器乐曲〔尤指钢琴曲〕。 5.滑稽;丑态。 I never saw such a sketch. 从来没有见过这种丑态。 make a sketch 速写,画草图。 vt. 1.给…绘草图;给…作速写。 2.草拟,拟订;记述…的概要,说出…的大意。 vi. 绘草图,作速写。 sketch (out) a plan [scheme] 草拟计划。
( 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 )研究了基于草图轮廓的拉伸与旋转特征模型重建的生成方法,以实例零件说明本文提出的重建方法是切实可行的。
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 当前主流的3dcad软件如catia 、 pro engineer等在实体建模时主要是基于草图设计的。本文在特征数据分割的基础上,结合正向设计的思路,着重研究结构件中的拉伸、旋转等基于草图的特征模型重建问题。
