Copyright Goodheart-Willcox Co., Inc. Chapter 14 Model Documentation, Analysis, and File Exchange 375 Type As discussed earlier, the section object is in one of four states. The four states are section plane, section slice, section boundary, and section volume. To change the state of the section object, select the Type property. Then, pick the state in the drop-down list. Live Section Live sectioning is a tool that allows you to dynamically view the internal features of a model as the section object is moved. This tool is discussed later in the chapter. To turn live sectioning on or off, select the Live Section property. Then, pick either Yes (on) or No (off) in the drop-down list. This is the same as turning live sectioning on or off using the ribbon or the shortcut menu. Plane Transparency The Plane Transparency property determines the opacity of the plane for the section object. The property value can range from 1 to 100. The lower the value, the more opaque the section plane object. See Figure 14-34. Plane Color The plane of the section object can be set to any color available in the Select Color dialog box. To change the color, select the Plane Color property and then select a color from the drop-down list. To select a color in the Select Color dialog box, pick the Select Color… entry in the drop-down list. This property only affects the plane of the section object, not the lines defi ning the boundary, volume, or section line. The color of these lines is controlled by the Color property in the General category. Section Object Grips When the translucent planes of a section object or the lines representing the section object state are picked, grips are displayed. The specifi c grips displayed are related to the current section object state. The types of grips are: • Base grip. • Menu grip. • Direction grip. • Second grip. • Arrow grips. • Segment end grips. Base Grip The base grip appears at the fi rst point picked when defi ning the section object. See Figure 14-35. It is the grip about which the section object can be rotated and scaled. The section object can also be moved using this grip. A B Figure 14-34. A—The Plane Transparency property of the section plane object is set to 1 (or 1% transparent). B—The Plane Transparency property of the section plane object is set to 85 (or 85% transparent).
