Learning Objectives After completing this chapter, you will be able to: Use the viewport controls to display views and control the display of view- navigation tools. Use the navigation bar to perform a variety of display manipulation functions. Create and save named views. Use the view cube to rotate the view of the model dynamically in 3D space. Use the view cube to display orthographic plan views of all sides on the model. Use steering wheels to display a 3D model from any angle. AutoCAD provides several tools with which you can display and present 3D models in pictorial and orthographic views: The viewport controls, discussed in Chapter 1. Preset isometric viewpoints, discussed in Chapter 1. The view cube. This on-screen tool provides access to preset and dynamic display options. Steering wheels. The 3DORBIT, 3DFORBIT, and 3DCORBIT commands. These commands provide dynamic display and continuous orbiting functions for demonstrations and presentations. Once a viewpoint has been selected, you can enhance the display by applying visual styles. The View panel in the Home tab of the ribbon provides a variety of ways to display a model, including wireframe representation, hidden line removal, and simple shading. An introduction to visual styles is provided in Chapter 1 and complete coverage is provided in Chapter 16. A more advanced representation can be produced by creating a rendering with the RENDER command. A rendering produces the most realistic image with high- lights, shading, and materials, if applied. Figure 3-1 shows a 3D model of a cast iron plumbing cleanout after using HIDE, setting the Conceptual visual style current, and using RENDER. Notice the difference in the three displays.
