TAILIEUCHUNG - Ebook Introduction to AutoCad 2010 - 2D and 2D Design: Part 2

(BQ) Part 2 book "Introduction to AutoCad 2010 - 2D and 2D Design" has contents: Introducing 3D modelling, 3D models in viewports, the modification of 3D models, building drawing, editing 3D solid models,. and other contents. | Part 2 3D Design Chapter 12 Introducing 3D modelling AIMS OF THIS CHAPTER The aims of this chapter are: 1. To introduce the tools used for the construction of 3D solid models. 2. To give examples of the construction of 3D solid models using tools from the Home/ Modeling panel. 3. To give examples of 2D outlines suitable as a basis for the construction of 3D solid models. 4. To give examples of constructions involving the Boolean operators Union, Subtract and Intersect. 223 224 Introduction to AutoCAD 2010 CHAPTER 12 Introduction As shown in Chapter 1 the AutoCAD coordinate system includes a third coordinate direction Z, which, when dealing with 2D drawing in previous chapters, has not been used. 3D model drawings make use of this third Z coordinate. The 3D Modeling workspace It is possible to construct 3D model drawings in the AutoCAD Classic or 2D Drafting & Annotation workspaces, but in Part 2 of this book we will be working in the 3D Modeling workspace. To set this workspace click the Workspace Settings icon in the status bar and select 3D Modeling from the menu which appears (Fig. ). The 3D Modeling workspace appears (Fig. ). Fig. Selecting 3D Modeling from the Workspace Switching menu Fig. The 3D Modeling workspace in Parallel projection The workspace in Fig. shows grid lines in Parallel projection mode, brought about by entering perspective at the command line, followed by entering 0 in response to the prompt which appears. This is the window in which the examples in this chapter will be constructed. Note the ViewCube at the top right-hand corner of the drawing area. In Fig. this has been highlighted by moving the cursor onto the cube. Changes can be made to the appearance and uses of the cube in the ViewCube Settings dialog brought to screen from the right-click menu of the ViewCube (Fig. ).
