緒論

UG軟件的功能特點

UG具有三維實體建模、裝配建模，生成直觀可視的數字虛擬產品，并對

其進行運動分析、干涉檢查、仿真運動及載荷分析.其功能特點如下：

.用造型來設計零部件，實現了設計思想的直觀描述；

.充分的設計柔性，使概念設計成為可能；

.提供了輔助設計與輔助分析的完整解決方案；

.圖形和數據的絕對一致及工程數據的自動更新.

UG與AutoCAD的差別

UG軟件有別于AutoCAD軟件,是一個交互的CAD/CAE/CAM/PDM系統，該系統的

CAD模塊提供一個真三維的設計環(huán)境,允許設計師精確地描述幾乎任一幾何形狀，通

過組合可對產品進行設計，分析和建立工程圖等.

使用UG獲得的潛在效益

.提高了效率，縮短產品從開發(fā)到投放商場的時間；

.使各種轉換錯誤達到最??；

.提供了較好的性能分析方法并減少了試驗次數；

.設計更標準化；

.保證設計適合于現代的制造技術；

.通過優(yōu)化設計，節(jié)約了材料和加工時間,降低了成本.

第一章UG操作入門

【內容提要】

本章將讓你了解Unigraphics的運行環(huán)境，界面.主要功能及基本操作.

第一節(jié)UG運行環(huán)境和安裝程序

§1.1.1UG安裝對軟硬件的基本要求

每一種軟件在其使用說明書中都有對其軟硬件環(huán)境提出基本要求,但這些要求通

常是能夠使用的最低要求.

使用UG15.0版本的最低硬件配置為：

.CPUIntelPentiumll266

.內存128MB

.顯示卡支持OpenGL功能的3D圖形加速顯示卡（8MB顯示緩存

至少支持1280X1024真彩色）

.顯示器17英寸高性能圖形顯示器

.硬盤2GB

.鼠標高性能三鍵鼠標

.光驅8X只讀光驅

.網卡以太網卡

使用UG15.0版本對軟件系統的基本要求為：

WindowsNT4.0中文版或英文版（Server或Workstation版均可）或WindowsNT

ServicePack5,Exceed&Exceed3D6.0（UGI6不需此軟件）.

UG16建議裝在WinNTSP6或Windows2000SPl下使用。

§1.1.2UG的安裝過程

.WindowsNT操作系統的安裝

.Exceed的安裝（UG16.0不需安裝此軟件），包括安裝Exceed3D.

.UG的安裝

第二節(jié)UG基本操作

§1.2.1鼠標功能應用

UG使用三鍵鼠標，其功能如下

三鍵鼠標按鍵功能

鼠標按鍵使用時機可執(zhí)行的動作

左鍵(MB1)繪圖區(qū)選取或是拖拉物體

<ctrl>MB1繪圖區(qū)當系統Preference>Seleclion>Confirmation(?F

關式設定)設定為OFF時，按此功能鍵，則系統會

顯示確認的訊息對話框;若設定為ON此功能鍵

無效.

<ctrl>MBl表列設定對話框重復選取圖層編號

(List)

<shift>MBl繪圖區(qū)取消選取

<shift>MBl表列設定對話框連續(xù)選取對象編號

(List)

<ctrl><shift>繪圖區(qū)取消選取并選取下一個

MB1

中鍵MB2繪圖區(qū)確定(ok)

<Alt>MB2繪圖區(qū)取消(cancel)

右鍵MB3繪圖區(qū)開取彈出或菜單

<shift>MB3基本曲線開啟基本曲線副菜單

(Basiccurve)

§1.2.2UG登錄

.激活機器,WinNT4按屏幕提示按下“PressCtrl+Alt+Delete”鍵(圖1.1),

Wind2000則直接：

—盅現LoginInformation對話框.在Username欄輸入你的登入NT或Win2K的用戶

名及PASSWORD,OK.

―?Start菜單中Programs>UnigraphicsVI6.0>Unigraphics,進入UG工作接口：

§1.2.3工作界面介紹

該小節(jié)將介紹UG完整的工作接口與各部分的功能.

下圖為UG15接口的圖標（圖1.2A）:

UG16的接口的圖標（圖1.2B）:

一窗口標題欄

.主要功能：顯示軟件版本與使用者應用模塊名稱，UG15的如（圖1.3A）.

二主菜單

包含了軟件所有主要的功能,UG15共有十六項.包括檔案(File)、編修(Edit)、

工具箱(Toolbox)、安排(Arrange)、組件(Assembly)、視圖(View)、布圖

(layout)、工作坐標(WCS)、圖層(Layer)、咨詢(Info)、參數設定(Preference)

、應用模塊(Application)、宏(Macro)、自定工具(UserTools)、網頁

(Web)、說明(Help)(圖1.4A).
