(4)分析与仿真Analysis & Simulation提供实体的网格划分(mesh)与静力、共振等有限元分析功能,并可输出网格分割数据共其它分析软件使用。

(5)APC 工厂布局提供工厂的规划建制功能。

(6)数控加工NC Manufacturing包含两轴到五轴加工的编程能力,并支持快速原型功能(STL Rapid Prototyping)。

(7)数字化仿真Digital Mockup包含动态机构仿真、装配配合空间分析、产品功能分析与功能优化等。

(8)设备与系统Equipment and Systems提供各种系统设备的建置,管路和电线的配置以及电子零件配置等功能。

(9)制造的数字化过程Digital Process for Manufacturing 提供在三维空间中进行产品的特征、公差与配合标注等功能。

(10)人体工学设计与分析Ergonomics Design&Anaysis提供人体模型,并可对产品进行人体空间分析。

(11)智能软件Knowledgeware一. 基本使用环境本章主要介绍CA TIA用户的基本操作界面、使用技巧、树结构(Tree)以及文件File、编辑Edit和视图View等菜单的操作等。

2.1 CATIA 的用户界面CATIA User Interface操作窗口菜单及工具条CA TIA对话框的组成2.2 操作技巧1. 鼠标的使用(1)使用三键鼠标,利用鼠标可以完成数种功能,包括选择和编辑对象、移动视角、右击打开弹出式菜单、旋转视角、物体的缩放等,具体使用如下:(2)选择和编辑对象:点击MB1(3)移动物体Translate:用MB2,按住中间不放,则物体随鼠标的移动而移动。

(移动物体的视角)(4)打开弹处菜单:用MB3,在物体上单击右键,可打开快捷菜单。

(5)旋转物体Rotate:用MB2+MB1或MB2+MB3,现按中键,再按右键或左键不放,移动鼠标即可。

点击中键可确定旋转中心。

(6)物体缩放ZOOM:按中键MB2,再点击右键MB2或左键MB1,向上是放大物体,向下是缩小。

2. 指南针Compass指南针(Compass)代表三维坐标系统。

帮助用户建立空间概念和了解坐标系统。

You can use a graphic manipulator referred to as the 3D compass to perform a certain number of manipulations on certain objects created and managed by certain applications (for example, Product Structure, Assembly, FreeStyle Shaper, DMU Navigator, etc.). 通过指南针,用户可以在Product Structure, Assembly, FreeStyle Shaper, DMU Navigator等过程中完成一系列的操作,如指定物体左X Y Z三轴的旋转和平移、在XY YZ ZX平面上的移动等,提高操作效率。

The 3D compass lets you:●manipulate viewpoints using the mouse and compass: this is just another way ofpanning and rotating all objects in the document at the same time●move and rotate non-constrained objects using the mouse and compassMoving objects in this context means physically moving them so as toredefine their spatial coordinates with respect to the absolute axis systemin a document. Moving should not be confused with panning an object,which simply modifies the viewpoint from which you look at an object: theposition of the object in the document remains the same.●move and rotate non-constrained objects using the Edit... contextual command●lock the compass orientation●snap the compass automatically onto a selected object●set the plane in which you move objects parallel to the screen●switch the privileged plane(优先)to the XZ or YZ planes of the compass●use the privileged plane as a working plane in applications such as the FreeStyleShaper application, for example, when manipulating control point manipulators on planar patches and curves.注意:You can use the 3D compass to manipulate non-constrained objects, in other words, objects not linked together by constraints. However, you can manipulate groups of objects in assemblies which are linked to each other by constraints.使用指南针操作视点(Manipulating Viewpoints)的方法如下:(1)自由旋转:抓住指南针Z轴顶点,移动鼠标(2)旋转:抓住指南针平面上的弧线,移动鼠标(3)轴向移动pan along the direction of any axis (X, Y or Z) of the compass:抓住指南针上的轴线,移动鼠标(4)平面移动:抓住指南针上的平面,移动鼠标。

(5)单一物体的移动:抓住指南针上的红色方块,移动指南针到物体的任何一点,便可直接对物体进行平移、旋转等操作。

在装配时,此功能非常有用。

(6)快捷菜单:在指南针上单击右键,弹出快捷菜单●锁定当前方向Lock Current Orientation:固定当前视角●将优先平面的方向锁定为与屏幕平行的方向Lock Privileged Plane OrientationParallel to Screen:●使XY平面为优先平面Make ZX Plane Privileged Plane:指定XY平面为指南针的基准面。

●使YZ平面为优先平面Make ZX Plane Privileged Plane:●使ZX平面为优先平面Make ZX Plane Privileged Plane :●使优先平面最大程度可见Make Privileged Plane Most Visible:●自动抓取选定对象Snap Automatically to Selected Object:但击此项,再单击一个物体,指南针便指定到确定的物体上3. 选择物体Select Objects使用鼠标选择物体常用以下几种方法:(1)单选Simple Selection:●直接用鼠标的MB1单击物体;●在左边的“特征树Selection of Geometry of Tree Feature”上单击物体的名称,即可选择对应的物体,被选择的物体会高亮显示。

Selection of geometry or of feature(s) in the tree(2)一次选多个物体Selection of Several Objects (Multi-selection):按Ctrl 键,用鼠标MB1点击多个物体,即可选择多个物体。

(3)直接用“编辑Edit”菜单中的“搜索Search”,按指定的属性选择有同一属性的物体。

(4)利用“选择工具SelectToolbar”拖动鼠标➢Select the Select iconto enter selectionmode, if it is not already activated.➢Drag (using the left mouse button).➢ A bounding outline will appear as you drag:➢Drag the bounding outline until the object(s) you want to select is(are) completely inside the bounding outline. (The objects must be completelyinside the bounding outline: if not, they will not be selected. )➢Release the mouse.➢The objects will be highlighted to indicate they have been selected.4. 使用层和层过滤器Using Layers and Layer Filters几何属性工具条(The Graphic Properties toolbar)设置物体的几何属性。
