【摘要】 传统的机械设计模式是工程师首先有三维的整体布局,然后用二维的装配图表达。只有少数设计师能够直接描绘示意性的三维轴测图,但是也难于作为精确的没计图纸。上世纪后期,研究者致力于二维装配图的“三维”重建。现在有了条件,可利用Autodesklnventor实现人机交互的三维总图设计,以及零部件的二维表达本文以组合机床设计为例,阐述该计算机辅助设计系统的开发,详述各个部分的功能。为进一步完善这个系统提供条件。更多还原

【Abstract】 Conventionally,mechanical engineers design the schematic 3D layout at first,and then represent it in 2D,assembly drawing.This 3D layout can be only expressed in 3D isometric projection by quite a few masters.But,it can be hardly used as precise engineering drawing.In the last decades,researchers undertook works on 3D reconstruction.Nowadays,computer-aided 3D assembly drawing can be implemented by using CAD software systems.Accordingly,the unit assembly and detail drawing can be done automatically.Employing the combine machine tool design as an example,this paper describes the development of such a CAD system using Autodesk Inventor.Various functional modes are detailed.It would be done valuable for further improvement.更多还原
