Build Parcel Fabric (Parcel)

Summary

Builds parcels in a parcel fabric. Parcels can be built from polygons or lines. If parcels are built from polygons, the tool creates parcel lines and parcel points. If parcels are built from lines, the tool creates the missing polygons and points. When building parcels from lines, parcel seeds are required.

Additionally, the following data is updated:

• Parcel record polygons are updated to match the cumulative geometry of all the parcels associated to them.
• The Parcel Count field on the Records feature class is updated with the number of parcels associated to each record.
• If the COGO Accuracy field on the Records feature class has an accuracy value, it will be transferred to the COGO Accuracy field of all the lines associated to the record.

Note:

Record polygons are not created or updated when more than 2,000 parcels are associated to a record.

Usage

• Use this tool when building an entire parcel fabric dataset or a large number of parcels.

• Parcel topology must be enabled.

• If parcel polygons or lines are associated with a parcel record, the created features will be associated with the same record. Record polygons will be updated.

• When building parcels from polygons, a single line is created for adjacent boundaries.

  If adjacent polygons are from adjacent records, the line is associated with the record with the most recent recorded date. If the recorded date is not specified, the line is assigned to the record that was most recently created in the database (the Created Date field). If the database creation dates are equal, the line is randomly assigned to one of the records.

Syntax

arcpy.parcel.BuildParcelFabric(in_parcel_fabric, {extent}, {record_name})

Parameter	Explanation	Data Type
in_parcel_fabric	The parcel fabric for which to build parcels. The parcel fabric can be from a file geodatabase or a feature service.	Parcel Layer
extent (Optional)	The extent of the dataset to be processed. Only features that fall within the specified extent will be processed. MAXOF—The maximum extent of all inputs will be used. MINOF—The minimum area common to all inputs will be used. DISPLAY—The extent is equal to the visible display. Layer name—The extent of the specified layer will be used. Extent object—The extent of the specified object will be used. Space delimited string of coordinates—The extent of the specified string will be used. Coordinates are expressed in the order of x-min, y-min, x-max, y-max.	Extent
record_name (Optional)	The name of the existing parcel record. Only parcels associated to this record will be built.	String

Derived Output

Name	Explanation	Data Type
updated_parcel_fabric	The updated parcel fabric.	Parcel Fabric

Code sample

BuildParcelFabric example (Python window)

The following Python window script demonstrates how to use the BuildParcelFabric tool in immediate mode. The script builds parcels using the combined extent of all input data (MAXOF).

import arcpy
arcpy.parcel.BuildParcelFabric("C:/Data/Database.gdb/Parcels/CountyFabric", 
                               "MAXOF")

Environments

This tool does not use any geoprocessing environments.
