Select the objects to extend nearest the end to be extended and then press Enter.
You can select the objects using one or more of these automatic methods:
Select the objects to be extended individually nearest the end to be extended.
Specify a two-point fence by clicking two different points in empty areas as a two-point fence that crosses the objects to be extended.
Click and drag your cursor across the objects to be extended as a freehand selection.
Note: These steps work for the Quick mode. For Standard mode, you select the boundaries for extending first and press Enter. Then you select the objects to be extended.
