Computer-Adided Design or simply CAD is a computer technology that computer programs, applications, and resources are used to create, update, evaluate a design which is generally a graphical design in different types.

Computer-Adided Design或简称为CAD是一种计算机技术，计算机程序，应用程序和资源用于创建，更新和评估设计，该设计通常是不同类型的图形设计。

计算机辅助设计(CAD)类型 (Computer-Aided Design (CAD) Types)

Computer-Aided Design can be accomplished with different types of software according to the design aim. In general, the following categories can be used for CAD classification.

根据设计目的，可以使用不同类型的软件来完成计算机辅助设计。 通常，以下类别可用于CAD分类。

• 2D CAD is the process of designing and creating a design that has only 2 spaces x and y coordinates like a 2D movie. This is the most basic and easy type of CAD.

  2D CAD是设计和创建仅具有2个空间x和y坐标(如2D电影)的设计的过程。 这是最基本，最简单的CAD类型。

• 3D CAD is the process of designing and creating a design that has only 3 spaces x, y and z coordinates like a 3D movie or real life. This type of CAD design is far harder to create according to 2D CAD Design.

  3D CAD是设计和创建仅具有3个空间x，y和z坐标(如3D电影或现实生活)的设计的过程。 根据2D CAD设计，很难创建这种类型的CAD设计。

• 3D CAD Surface Modelling is the process of detailing the surfaces of the 3D object which has been already designed.

  3D CAD Surface Modelling是详细说明已经设计的3D对象表面的过程。

• Solid Modelling is the process of modeling solid object like a real-life object.

  Solid Modelling是对实体对象(如现实生活中的对象)进行建模的过程。

计算机辅助设计(CAD)的优势 ( Computer-Aided Design (CAD) Advantages )

A design can be done by using different methods wherein the old-time hand made design was defacto standard. With the advancement of computers, the design also changed and special applications are created to help the design processes. Computer-Aided Design has a lot of advantages over other types of designs which are listed below.

可以通过使用不同的方法来完成设计，其中旧的手工设计是事实上的标准。 随着计算机的进步，设计也发生了变化，并创建了特殊的应用程序来帮助设计过程。 与以下列出的其他类型的设计相比，计算机辅助设计具有很多优势。

• Designs can be updated without erasing and redrawing.无需删除和重画就可以更新设计。
• The design can be zoomed with CAD easily.可以使用CAD轻松缩放设计。
• 3D designs can be easily created.可以轻松创建3D设计。
• 3D design can easily be rotated on any axis without a problem in a fast way.3D设计可以轻松地在任何轴上快速旋转而不会出现问题。
• Viewing a CAD is easy to view and showcase from different angles and axis.查看CAD很容易从不同的角度和轴进行查看和展示。
• Ready o use components can be used without the need to recreate them.可以使用即用型组件，而无需重新创建它们。
• Creating designs are a lot easier and faster.创建设计变得更加容易和快捷。
• Sharing CAD design is very easy which can be published using the internet or sent to specific people via email.共享CAD设计非常容易，可以使用Internet发布或通过电子邮件发送给特定的人。
• Copying CAD design is very easy where the design file can be copy and pasted or cloned via CAD software.复制CAD设计非常容易，可以通过CAD软件复制和粘贴或克隆设计文件。

什么是CAD软件？ (What Is CAD Software?)

What makes CAD so advantageous is the CAD software. CAD Software is used to create, update, change, view, publish CAD designs. CAD software provides a very complex GUI for designing. Below we can see the popular CAD software named AutoCAD GUI.

使CAD如此具有优势的是CAD软件。 CAD软件用于创建，更新，更改，查看，发布CAD设计。 CAD软件为设计提供了非常复杂的GUI。 在下面，我们可以看到流行的CAD软件AutoCAD GUI。

1. This part is the menu that provides access to all features, screens of the AutoCAD.该部分是菜单，可用于访问AutoCAD的所有功能和屏幕。
2. This part is the tools that provide the tools which are used during design.这部分是提供在设计过程中使用的工具的工具。
3. This part is the Object Properties where the created objects properties are listed and can be changed.这部分是“对象属性”，其中列出了可以更改的创建对象属性。
4. This part is the GUI view of the design.这部分是设计的GUI视图。
5. This part is the navigation pane where the GUI view of the design can be navigated easily for x,y, and z-axis.这部分是导航窗格，可以在其中轻松浏览设计的GUI视图的x，y和z轴。
