530 AutoCAD and Its Applications—Advanced Copyright Goodheart-Willcox Co., Inc. Understanding Show Motion Understanding Show Motion Show motion is simply a means for creating, manipulating, and displaying named views. The NAVSMOTION command is used for show motion. The process involves the creation of shots using the ShowMotion toolbar and the New View/Shot Properties dialog box. Once a shot is created, you can give it properties that allow it to be displayed in many different ways. If a saved shot does not display in the manner you desire, it is easily modifi ed. A view category is a heading under which different views are fi led. It is not neces- sary to create view categories, especially if you will be making just a few views. On the other hand, if you are working on a complex model and need to create a number of views with a variety of cinematic and motion characteristics, it may be wise to create view categories. The process of using show motion to create, modify, and display shots begins by fi rst using the ShowMotion toolbar. All of your work with shots will be performed using the New View/Shot Properties dialog box. Options in this dialog box change based on the type of shot that is selected. These options are discussed in the sections that follow relating to each kind of shot. PROFESSIONAL TIP PROFESSIONAL TIP As you fi rst start working with show motion, you may want to create view categories named Still, Cinematic, and Walk. As you create shots, fi le each under its appropriate cate- gory name. This will assist you in seeing how the different shot-creation techniques work. Later, you can apply the view categories to specifi c components of a complex model. For example, a subassembly of a 3D model may have a view category that contains all three types of shots for use in different types of modeling work or presentations. Creating and using view categories is discussed in detail at the end of this chapter. Show Motion Toolbar Show Motion Toolbar The ShowMotion toolbar is displayed at the bottom-center of the screen when the NAVSMOTION command is entered. See Figure 20-1. The quickest way to display the ShowMotion toolbar is to pick the ShowMotion button on the navigation bar. The ShowMotion toolbar provides controls for creating and manipulating views: • Unpin ShowMotion/Pin ShowMotion • Play All • Stop • Turn on Looping • New Shot… • Close ShowMotion When the toolbar is pinned, it remains displayed if you execute other commands, minimize the drawing, change ribbon panels, or switch to another software applica- tion. The Unpin ShowMotion button is used to unpin the toolbar. The Pin ShowMotion button is then displayed in its place. If you unpin the toolbar, you must execute the NAVSMOTION command each time you wish to use show motion. Pick the Play All button to play all of the shots displayed as thumbnails above the toolbar. The playback of these shots will loop (repeat) if the Turn on Looping button is selected. If looping is turned on, a shot, category, or all categories are displayed in a loop whenever the Play All button is selected. The Turn on Looping button is a toggle. The button image changes to indicate whether looping is turned on. NAVSMOTION Type NAVSMOTION MOTION Toolbar Navigation Bar Render ShowMotion
