计算机辅助工业设计课程已经开课三周了，我们学校和大多数的一样，用的是Rhino教学，而不是清华、华南理工的Alias,上周的作业是鼠标和自选小玩意。

感觉犀牛这软件使用很方便，寒假初步探索过Alias Automotive,犀牛在人机界面的设计大大简化于Alias，例如，在Rhino中移动一个物件只需要两步——选择、拉拽，而在Alias中需要经历选择、Transform-Move、拉拽,当然，个人还是相当喜欢Alias逻辑性很强的人机交互的。对于希望快速表达自己想法出效果图（主要是渲染图，Alias那种Paint + Modeling的混合快速表现还是很{wd}的）的建模动机，个人认为{sx}犀牛，需要精细建模以至提交工业制造，Alias优势是巨大的。

鼠标那个作业，现在想想自己做的太简单了，设计不足，自选小玩意那个，本着不搞大不罢休的原则，硬是把自己那个Logitech Precision游戏手柄给做出来了，而且一定要精细到每个小按键，虽然曲面质量远低于原品，但我尽力了。

It has been almost 3 weeks since the Computer Aided Industrial Design course began,like most colleges,we use Rhino but not Alias like Tsinghua and so on.Last week's homework was computer mouse and a gadget chosen by selves.

Rhino is quite a friendly modelling tool,I explored Autodesk Alias initially in winter vacation,Rhino's human-machine interface design is much simplified than Alias,take moving an object as an example,in Rhino,you need to select and drag,2 steps,but in Alias,you need to select,find Move key in Pallete's Transform section or enter the move command or something like that,and then the drag stage,however I still like the very logical H-M interaction of Alias. For modelling motivations like quick express via rendering it's primarily suggested to do with Rhino,personally,for very accurate industrial level modelling,Alias has enormous advantage.
