Copyright Goodheart-Willcox Co., Inc. 380 AutoCAD and Its Applications—Advanced Intersection Boundary The intersection boundary is where the model is intersected by the section object. It is represented by line segments. You can set the color, linetype, linetype scale, and line weight of the intersection boundary lines. Intersection Fill The intersection fi ll is the material visible on the model surface where the section object cuts. It is displayed as a solid fi ll, by default. Any hatch pattern available in AutoCAD can be used as the intersection fi ll. See Figure 14-41A. The angle, hatch scale, hatch spacing, and color can be set. In addition, the linetype, linetype scale, and line weight can be changed. The fi ll pattern can even be set to be transparent. Cutaway Geometry The cutaway geometry is the part of the model removed by the live sectioning. By default, this geometry is not displayed. Changing the Show property to Yes displays the geometry. See Figure 14-41B. You can set the color, linetype, linetype scale, and line weight of the lines representing the cutaway geometry. In addition, the Face Transparency and Edge Transparency properties allow you to create a see-through effect, as seen in Figure 14-42. Each of these two properties is set to 50 by default. PROFESSIONAL TIP PROFESSIONAL TIP You can also display the cutaway geometry without using the Section Settings dialog box. Select the section object, right-click, and pick Show cut-away geometry in the shortcut menu. Live sectioning must be on. C B A Figure 14-40. Section settings. A—For a 2D block. B—For a 3D block.
