計算機輔助設計 課件

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或簡稱為CAD是一種計算機技術，計算機程式，應用程式和資源用於建立，更新和評估設計，該設計通常是不同型別的圖形設計。

計算機輔助設計(CAD)型別 (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.

根據設計目的，可以使用不同型別的軟體來完成計算機輔助設計。 通常，以下類別可用於CAD分類。

• 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是設計和建立僅具有2個空間x和y座標(如2D電影)的設計的過程。 這是最基本，最簡單的CAD型別。

• 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是設計和建立僅具有3個空間x，y和z座標(如3D電影或現實生活)的設計的過程。 根據2D CAD設計，很難建立這種型別的CAD設計。

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

  3D CAD Surface Modelling是詳細說明已經設計的3D物件表面的過程。

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

  Solid Modelling是對實體物件(如現實生活中的物件)進行建模的過程。

計算機輔助設計(CAD)的優勢 ( 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.

可以通過使用不同的方法來完成設計，其中舊的手工設計是事實上的標準。 隨著計算機的進步，設計也發生了變化，並建立了特殊的應用程式來幫助設計過程。 與以下列出的其他型別的設計相比，計算機輔助設計具有很多優勢。

• Designs can be updated without erasing and redrawing.
  無需刪除和重畫就可以更新設計。
• The design can be zoomed with CAD easily.
  可以使用CAD輕鬆縮放設計。
• 3D designs can be easily created.
  可以輕鬆建立3D設計。
• 3D design can easily be rotated on any axis without a problem in a fast way.
  3D設計可以輕鬆地在任何軸上快速旋轉而不會出現問題。
• Viewing a CAD is easy to view and showcase from different angles and axis.
  檢視CAD很容易從不同的角度和軸進行檢視和展示。
• Ready o use components can be used without the need to recreate them.
  可以使用即用型元件，而無需重新建立它們。
• Creating designs are a lot easier and faster.
  建立設計變得更加容易和快捷。
• Sharing CAD design is very easy which can be published using the internet or sent to specific people via email.
  共享CAD設計非常容易，可以使用Internet釋出或通過電子郵件傳送給特定的人。
• Copying CAD design is very easy where the design file can be copy and pasted or cloned via CAD software.
  複製CAD設計非常容易，可以通過CAD軟體複製和貼上或克隆設計檔案。

什麼是CAD軟體？ (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如此具有優勢的是CAD軟體。 CAD軟體用於建立，更新，更改，檢視，釋出CAD設計。 CAD軟體為設計提供了非常複雜的GUI。 在下面，我們可以看到流行的CAD軟體AutoCAD GUI。

1. This part is the menu that provides access to all features, screens of the AutoCAD.
   該部分是選單，可用於訪問AutoCAD的所有功能和螢幕。
2. This part is the tools that provide the tools which are used during design.
   這部分是提供在設計過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.
   這部分是“物件屬性”，其中列出了可以更改的建立物件屬性。
4. This part is the GUI view of the design.
   這部分是設計的GUI檢視。
5. This part is the navigation pane where the GUI view of the design can be navigated easily for x,y, and z-axis.
   這部分是導航窗格，可以在其中輕鬆瀏覽設計的GUI檢視的x，y和z軸。
