The Load A Topology To A Parcel Fabric geoprocessing tool is performance intensive, and the number of parcels you can load at a time will depend on your computer configuration and memory availability. When working with a large parcel dataset, you can either split up the dataset into manageable sections of data or load selections of polygons or lines.

The Iteratively Load To The Parcel Fabric geoprocessing model can be used to iteratively load a topology to a parcel fabric based on an overlapping polygon grid.

Follow these steps to iteratively load a large topology to a parcel fabric.

  1. Download the Iteratively Load To The Parcel Fabric geoprocessing model .
    2. Use the Create Fishnet geoprocessing tool to create a polygon grid overlaps the topology you want to load. The iterative loading model will loop through each grid cell and select and load the underlying data:
  2. Open ArcMap and add the topology that will be loaded to the parcel fabric. Make sure to add its participating feature classes to the map.
  3. Open the Create Fishnet geoprocessing tool.
  4. On the Create Fishnet dialog box, enter a name and path for your polygon grid under Output Feature Class.
  5. Choose the topology from the Template Extent drop-down list.
    6. In this step, you are specifying an extent for the fishnet grid. You can also use either the line or polygon feature class.
  6. Enter 0 for both the Cell Size Width and Cell Size Height.
  7. Enter the number of rows and number of columns the fishnet will have under Number of Rows and Number of Columns.
    8. The larger the dataset, the larger the number will be of rows and columns. Set the fishnet up so that no more than 30,000 to 50,000 parcels are imported for each iteration. The number of parcels loaded during each iteration will depend on your computer configuration and memory availability.
  8. Uncheck Create Label Points.
  9. Choose POLYGON from the Geometry Type drop-down list and click OK to create the fishnet .
  10. Navigate to the location of the downloaded iterative loading model and double-click the Iterate toolbox to open it.
    11. Double-click the FabricLoad_Iterate geoprocessing model to open it.
  11. On the FabricLoad_Iterate dialog box, choose the fishnet you created from the Grid input drop-down list.
  12. Leave Group By Fields blank. Choose the source parcel polygons as the Input Feature Layer, and specify a parcel fabric for the Target Parcel Fabric.
  13. Populate the remaining tool parameters, and click OK to iteratively load the data.
