Chapter 20 Using Show Motion to View a Model 533 Copyright Goodheart-Willcox Co., Inc. Visual Settings The options in the Settings area of the View Properties tab apply to the overall display of the model in the shot. When the Save layer snapshot with view check box is checked, all of the current layer visibility settings are saved with the new shot. This is checked by default. Any UCS currently defi ned in the drawing can be selected for use with the new shot. Use the UCS: drop-down list to select the UCS. When the shot is restored, that UCS is restored, too. If you select None in the drop-down list, there is no UCS associ- ated with the shot. Live sectioning is a tool that allows you to view the internal features of 3D solids that are cut by a section plane object. This feature is covered in detail in Chapter 14. When a section plane object is created, it is given a name. Therefore, if a model contains one or more section plane objects, their names appear in the Live section: drop-down list. If a section plane object is selected in this list, the new shot shows the live sectioning for that plane. The Visual style: drop-down list contains all visual styles in the drawing plus the options of Current and None. Selecting a visual style from the list results in that style being set current when the shot is played. Selecting Current or None will cause the shot to be displayed in the visual style currently displayed on the screen. A detailed discussion of visual styles is provided in Chapter 16. NOTE NOTE A shot created with live sectioning on will be displayed in that manner even though live sectioning may be currently turned off in the drawing. However, subsequent displays of the model that were created with live sectioning off are shown with it on. Keep this in mind as you develop shots for show motion. Background Settings The Background area of the View Properties tab provides options for changing the background of the new shot. The drop-down list in this area allows you to select a solid, gradient, image, or sun and sky background. You can also choose to retain the default back- ground. If you pick Solid, Gradient, or Image, the Background dialog box appears. If you select Sun & Sky, the Adjust Sun & Sky Background dialog box appears. These dialog boxes are used to set the background and are discussed in detail in Chapter 18. The Save sun properties with view setting is used to apply the sunlight data to the view. If you are displaying an architectural model using sunlight, you will likely want this check box checked for show motion. Sunlight and geographic location are discussed in detail in Chapter 18. Shot Properties Tab Settings in the Shot Properties tab of the New View/Shot Properties dialog box provide options for controlling the transition and motion of shots. There are numerous movement and motion options in this tab. The specifi c options available are based on the type of shot selected: still, walk, or cinematic. In addition, the cinematic shot contains a variety of motions that can be applied to the shot and each type of motion contains a number of variables. The options in the Shot Properties tab are discussed later in this chapter as they apply to different shots, movements, and motions.
