This section shows you how to modify features that already exist in your vector data—shapefiles, ArcPad AXF files, or graphics layers. The editing tools, commands, and tasks provide a variety of ways to make changes to the geometry and attributes of existing features. For example, you can extend a line by adding vertices to the start or end of the line. You can also reshape line and polygon features by adding, moving, or deleting vertices. Editing of existing features is done using the mouse pointer, pen, incoming GPS coordinates, or offsets. Attributes of existing or new features can be edited via the

Attributes page of the Feature Properties dialog box, or via custom forms. Attributes in related tables can also be edited for ArcPad AXF files which have relationships defined.
