绪论

UG软件的功能特点

UG具有三维实体建模、装配建模，生成直观可视的数字虚拟产品，并对

其进行运动分析、干涉检查、仿真运动及载荷分析.其功能特点如下：

.用造型来设计零部件，实现了设计思想的直观描述；

.充分的设计柔性，使概念设计成为可能；

.提供了辅助设计与辅助分析的完整解决方案；

.图形和数据的绝对一致及工程数据的自动更新.

UG与AutoCAD的差别

UG软件有别于AutoCAD软件,是一个交互的CAD/CAE/CAM/PDM系统，该系统的

CAD模块提供一个真三维的设计环境,允许设计师精确地描述几乎任一几何形状，通

过组合可对产品进行设计，分析和建立工程图等.

使用UG获得的潜在效益

.提高了效率，缩短产品从开发到投放商场的时间；

.使各种转换错误达到最小；

.提供了较好的性能分析方法并减少了试验次数；

.设计更标准化；

.保证设计适合于现代的制造技术；

.通过优化设计，节约了材料和加工时间,降低了成本.

第一章UG操作入门

【内容提要】

本章将让你了解Unigraphics的运行环境，界面.主要功能及基本操作.

第一节UG运行环境和安装程序

§1.1.1UG安装对软硬件的基本要求

每一种软件在其使用说明书中都有对其软硬件环境提出基本要求,但这些要求通

常是能够使用的最低要求.

使用UG15.0版本的最低硬件配置为：

.CPUIntelPentiumll266

.内存128MB

.显示卡支持OpenGL功能的3D图形加速显示卡（8MB显示缓存

至少支持1280X1024真彩色）

.显示器17英寸高性能图形显示器

.硬盘2GB

.鼠标高性能三键鼠标

.光驱8X只读光驱

.网卡以太网卡

使用UG15.0版本对软件系统的基本要求为：

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

ServicePack5,Exceed&Exceed3D6.0（UGI6不需此软件）.

UG16建议装在WinNTSP6或Windows2000SPl下使用。

§1.1.2UG的安装过程

.WindowsNT操作系统的安装

.Exceed的安装（UG16.0不需安装此软件），包括安装Exceed3D.

.UG的安装

第二节UG基本操作

§1.2.1鼠标功能应用

UG使用三键鼠标，其功能如下

三键鼠标按键功能

鼠标按键使用时机可执行的动作

左键(MB1)绘图区选取或是拖拉物体

<ctrl>MB1绘图区当系统Preference>Seleclion>Confirmation(?F

关式设定)设定为OFF时，按此功能键，则系统会

显示确认的讯息对话框;若设定为ON此功能键

无效.

<ctrl>MBl表列设定对话框重复选取图层编号

(List)

<shift>MBl绘图区取消选取

<shift>MBl表列设定对话框连续选取对象编号

(List)

<ctrl><shift>绘图区取消选取并选取下一个

MB1

中键MB2绘图区确定(ok)

<Alt>MB2绘图区取消(cancel)

右键MB3绘图区开取弹出或菜单

<shift>MB3基本曲线开启基本曲线副菜单

(Basiccurve)

§1.2.2UG登录

.激活机器,WinNT4按屏幕提示按下“PressCtrl+Alt+Delete”键(图1.1),

图1.1

10

Wind2000则直接：

—盅现LoginInformation对话框.在Username栏输入你的登入NT或Win2K的用户

名及PASSWORD,OK.

―►Start菜单中Programs>UnigraphicsVI6.0>Unigraphics,进入UG工作接口：

§1.2.3工作界面介绍

该小节将介绍UG完整的工作接口与各部分的功能.

下图为UG15接口的图标（图1.2A）:

UG16的接口的图标（图1.2B）:

一窗口标题栏

.主要功能：显示软件版本与使用者应用模块名称，UG15的如（图1.3A）.

QUnigraphicsV15.0.2-Modeling

图1.3A

UG16的如(图1.3B)：

23UnigraphicsV16.0-Gateway

图1.3B

二主菜单

包含了软件所有主要的功能,UG15共有十六项.包括档案(File)、编修(Edit)、

工具箱(Toolbox)、安排(Arrange)、组件(Assembly)、视图(View)、布图

(layout)、工作坐标(WCS)、图层(Layer)、咨询(Info)、参数设定(Preference)

、应用模块(Application)、宏(Macro)、自定工具(UserTools)、网页

(Web)、说明(Help)(图1.4A).

1File（档案）

进入工作接口后，首先要建立新文件（New）,或打开旧文件（Open）,才能激活工作

接口上的大部分命令（图1.5）.

New...Ctrl+N--------------新增

Open...Ctrl+O---------------临

Import...Ctrl+Shift+I傅入

Export...Ctrl+Shift+E傅出

Save能

Options逗项

Plot...Ctrl+P出圄

Utilities...公用程式

ExecuteUG/Open新增

ChangeDisplayedPart...Ctrl+Shift+D更换II下零件

Close躺

QuitCtrl+Q四

SaveAJIandExit端存全部后^

File>New,在Filter栏输入文件所在的盘

符和路径，回车，在Selection栏输入文件名，回车,

进入接口工作状态（图1.6）.

2Edit（编辑）

一般地，先进入应用模块（Application）中的模

型（Modeling）,才进行其它操作.

Application>Modeling,出现"Greate

Feature"对话框（图1.7）.再单击Edit下拉菜单,

出现图1.8.
