What selection method should you use to stretch one of an object's legs?

1. Window selection

2. Crossing window selection

3. Fence selection

4. Polygon selection

The correct answer is: Crossing window selection

Stretching one of an object's legs in AutoCAD typically involves modifying a specific segment of that object without affecting the entire shape. The crossing window selection method is particularly effective for this purpose because it allows you to select objects or parts of objects that are partially enclosed within the selection area, even if only a portion of the leg is included in the selection. When using a crossing window, the selection box is drawn from right to left, and it will select everything that the box intersects, including items that are partially or completely within that area. This characteristic makes it ideal for selecting specific segments of an object—like a leg—while leaving the rest untouched. In contrast, other selection methods do not provide the same flexibility. For instance, window selection requires that the entire object be enclosed within the selection box, which wouldn't work well for just stretching one leg. Fence selection is more about specifying a linear path, and while it can select objects, it is less straightforward for the particular task of stretching specific parts of an object. Polygon selection allows for more intricate selections but is generally more time-consuming and complex when working with simpler shapes like legs. Therefore, choosing crossing window selection maximizes efficiency and precision when modifying parts of an object in AutoCAD.
