Copyright DASSAULT SYSTEMES Generative Drafting Fundamentals (ISO) 第四部分：工程绘图 工程绘图简介：两种创建工程图的方式 工程图生成流程： 工程图生成步骤：连接器上盖 Accessing the Workbench Drafting Toolbars and Objects 几个概念 Drawing:单个零件或装配的完整工程图，可包括一张或若干张图纸（Sheet ）。 Sheet:单张图纸，可包括多个投影视图（View）。 View:画法几何中的投影视图，可分主视图（Front View）、辅助视图、局部视图等。 Detail Sheet:可存放多个组件（component）的图纸。 Component:可看作在图纸中可重复使用的图块。 Background和Working Views:Catia中一张图纸（sheet）可分为背景（Background）和工 作视图（Working Views），背景放置多张图纸共有的元素，如图框和标题栏等，工作视图放置工程图的主要内容，如投影视图和文字说明等，是每张图纸都不同的。两者可相互切换，编辑时互不干扰。 Drafting Terminology What is a Drawing? What are the different types of Views? Starting a Generative Drawing You will learn how to generate a drawing directly from a 3D part. How to Start a Generative Drawing from a CATPart? Classical Method to Start Generating a Drawing Setting Drawing Sheet Format and Drafting Standards Setting First Angle Projection Starting a Drawing with a Blank Sheet Defining the Main Views You will learn how to define the main views for a drawing using the View Wizard. The geometry will be generated into these views from the associated Part Document. Creating Views Creating a Front View Using Multi-Selection (1/2) Creating a Front View Using Multi-Selection (2/2) Rotating the Front View with View Manipulator (1/2) Rotating the Front View with View Manipulator (2/2) Adding a Projection View on a Drawing Additional View Generation In this lesson you will generate section, detail, auxiliary, isometric and broken views on a drawing Adding Section Views and Cuts Adding Secondary Views Additional Reference Material Summary Adding Section Views and Cuts You will learn how to add section views and section cuts to the drawing What are the different types of Sections Views ?
