Parcels are numbered automatically when you create them. By default, parcel names are based on the parcel style name template. You can manually renumber and/or rename them later.
Area parcels are numbered automatically in creation order, beginning with the Parcel: Next Automatic Area Counter in the Site Properties dialog box. When you renumber parcels, numbering begins with the Parcel: Next Manual Area Counter. The same concept applies to segment tags.
Tags are the label elements used as key values in parcel tables.
When numbering automatically, the increment is always 1. When numbering manually (renumbering), you can select the increment when beginning the renumbering process.
