Overview of moving vertex using offsets
If you are unable to reach the vertex, cannot receive a strong GPS signal, or are using a rangefinder, you can use offsets to move the vertex of a line or polygon.
In order to move a vertex of an existing line or polygon, you must use the Move To menu to open the Point/Vertex dialog box. In the Point/Vertex dialog box, select the Offset page to capture your offset.
Alternatively, you can use the Radial Traverse tool. The Radial Traverse tool requires that you set a reference point, either by tapping the screen or by using a GPS receiver.
