Chapter 14 Model Documentation, Analysis, and File Exchange 377 that the arrow grip is being used to extend the left side of the section plane past the boundary of the solid model. This allows any subsequent section views to display the entire object rather than just a portion of it. The right side of the section plane can be extended in the same manner using the opposite arrow grip. The arrow grips located on the line segments of the section plane move the posi- tion of the section plane. As a segment of the section plane is moved, it maintains its angular relationship and connection to any adjacent section plane segment. Segment End Grips The segment end grips are located at the end of each line segment defi ning the section object state. Refer to Figure 14-35. The number of displayed segment end grips depends on whether the section object is in the section plane, section slice, section boundary, or section volume state. These grips provide access to the standard grip editing options of stretch, move, copy, rotate, scale, and mirror. If the rotate option is used, the section plane is rotated about the selected segment end grip. Moving a segment end grip can change the angle between section plane segments. Adjusting Section Objects Additional editing functions for section objects are available in the Section Plane contextual ribbon tab. Refer to Figure 14-28. If you need to move a section object to show a different cut in the model, you can offset the section object by a specifi ed distance. Select the section object and enter a positive or negative offset value in the Section Offset text box in the Adjust panel. The section object is moved perpendicular to the section plane in a positive or negative direction relative to the WCS. See Figure 14-38. Picking the up or down arrow next to the Section Offset text box offsets the section plane by an incremental value in a positive or negative direction. The incremental value can be adjusted by picking the dialog box launcher button at the bottom of the Adjust panel to access the Adjust Panel Increments dialog box. A section object can also be rotated to show a different cut in the model. To rotate a section object in 90° increments, select the Rotate 90 option in the Modify panel. The section object rotates 90° about the section line, section boundary, or section volume, depending on the current section state. This provides an alternative method to using grips to rotate the section object. Drag the grip beyond the edge of the solid object Section extends beyond the solid object A B C Figure 14-37.
