Introduction to AutoCAD 2009 2D and 3D Design- P8: The purpose of writing this book is to produce a text suitable for students in Further and/or Higher Education who are required to learn how to use the CAD software package AutoCAD 2009. Students taking examinations based on computer-aided design will fi nd the contents of the book of great assistance. | 338 Introduction to AutoCad 2009 CHAPTER 17 3. The two-view projection Fig. 17.37 shows a ducting pipe. Construct a 3D model drawing of the pipe. Place in a SW Isometric view add lighting to the scene and a material to the model and render. Fig. 17.37 Exercise 3 - details of shapes and sizes 4. A point marking device is shown in two two-view projections Fig. 17.38 . The device is composed of three parts - a base an arm and a pin. Construct a 3D model of the assembled device and add Fig. 17.38 Exercise 4 - details of shapes and sizes Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Three-dimensional space 339 appropriate materials to each part. Then add lighting to the scene and render in an SW Isometric view Fig. 17.39 . CHAPTER 17 Fig. 17.39 Exercise 4 a rendering 5. A rendering of a 3D model drawing of the connecting device shown in the orthographic projection shown in Fig. 17.41 is given in Fig. 17.40. Construct the 3D model drawing of the device and add a suitable lighting to the scene. Then place in the ViewCube Isometric view add a material to the model and render.
