Adding new attributes to parcel fabric tables

This topic applies to ArcEditor and ArcInfo only.

A parcel fabric is composed of a set of internal feature classes and tables, for example, parcel lines, parcel polygons, and plans. Parcel fabric feature classes and tables behave like standard feature classes and tables in ArcGIS.

The Fabric Classes tab on the Parcel Fabric Properties dialog box contains a drop-down list of the internal feature classes and tables that compose a parcel fabric. Each feature class or table has a set of predefined, parcel fabric system attributes, which act like the system attributes of a normal feature class. Some system attributes are editable and some are entirely system-managed.

Additional attributes can be added to all fabric feature classes and tables the same way attributes are added to normal feature classes.

Note:

Additional attributes should not be added to the line points feature class of the parcel fabric as these additional attributes cannot be populated in the editor.

You can also add indexes to and create subtypes and domains on both system and additional, user-defined attributes on parcel fabric feature classes and tables.

External relationship classes can be created on all parcel fabric feature classes and tables; for example, you might want to create an external relationship class between your parcel fabric parcels feature class and an external parcel ownership table.

You may want to add attributes to fabric feature classes or tables before migrating across existing attributes from parcel-based feature classes. For example, you might have attributes on your existing parcel polygon data that are not represented in the system attributes of the parcel fabric parcels feature class (for example, ownership). You would then need to create a new attribute on the parcel fabric parcels feature class with the same name/type as the attribute in your source parcel polygon data for the attribute to migrate successfully into the parcel fabric. The same is true for migrating subtypes and domains. If subtypes and domains are defined on attributes in your existing parcel datasets, the same subtypes and domains need to be defined on the corresponding attributes in the parcel fabric feature classes and tables before migration.

The following parcel fabric feature classes and tables are available on the Fabric Classes tab of the Parcel Fabric Properties dialog box:

• Control points—Stores coordinates (x,y,z) of survey control points
• Points—Stores parcel corner points
• Lines—Stores parcel lines
• Parcels—Stores parcel polygons
• Line points—Represents parcel corner points that lie on but do not split the boundaries of adjacent parcels
• Plans (table)—Stores information from the record of survey
• Jobs (table)—Tracks edits to the parcel fabric
• History (table)—Tracks parcel history
• Adjustments (table)—Tracks feature adjustments
• Accuracy(table)—stores parcel fabric accuracy levels

Steps:

To add a new attribute to a table in the parcel fabric, perform the following:
1. Right-click the parcel fabric in the Catalog tree and click Properties.

   The Parcel Fabric Properties dialog box appears.

2. Click the Fabric Classes.
3. Choose a feature class or table from the Classes drop-down list.
4. In the list of fields, scroll down and click the next blank row in the Field Name column and type the name of your attribute field.
5. Click the Data Type column next to the new field's name and select its data type. Choose whether you want to allow null values by clicking in the blank field next to Allow NULL Values in the Field Properties and clicking the drop-down arrow.
6. Click Apply to create the attribute or OK to create the attribute and close the dialog box.
Tip:

To add an index to an attribute, click Properties on the Parcel Fabric Properties dialog box and click the Indexes tab on the Fabric Class Properties dialog box.

Tip:

To create a new subtype for an attribute, click the Properties button on the Parcel Fabric Properties dialog box and click the Subtypes tab on the Fabric Class Properties dialog box.

Tip:

To create a new relationship for a parcel fabric table, click the Properties button on the Parcel Fabric Properties dialog box and click the Relationshipstab on the Fabric Class Properties dialog box.
