机械设计过程剖析---讨论

天地一笑

机械设计过程：
7 U  O2 r; U' [（1）大脑中有一个大体的装配草图（机械结构简图到机械结构简图的设计）
& Q+ Z, O# s, C! e4 N# i（2）装配图的设计
# `( X5 b2 t. U. G. o（3）零件图的设计

8 `* V0 w! K0 i9 p: _4 F2 J这三个过程中第(1)步要绘制结构简图就不那么容易，不知道如何可以绘制好机械结构简图，是要学习《机械原理》？
（2）.(3)步需要很强的机械绘图能力，我在这方面也很弱，感觉自己直接用二维软件时绘图时比较困难。用三维软件先绘制成实体，然后在转变成二维还稍微轻松点。
期望大家给我点意见，谢谢了！

不知道有没有人做过流程图。 下面是我从美国Robert L. Norton 著的 "An Introduction to the Synthesis and Analysis of Mechanisms and Machines" 上摘录的，个人觉得有点意思，供参考。
