Creating a new feature and establishing new relationships

In this example you will see how to cut one of the current parcels into two different parcels and update its relationships with the Owners table. In order to cut the feature into two features you must start an edit session in ArcMap, set the edit task to Cut Polygon Feature and set the target layer to the Parcels layer.

Once the editing environment is set up select the Sketch tool and draw a line across the parcel where you would like to cut the polygon. After you have set the second vertex, right-click within the Data View window and select Finish Sketch or click F2 to cut the parcel in two. With the two edited features selected open the Attribute dialog to update the attributes of the parcels.

When the features were cut, the geometry of the original feature was updated and a new feature was created with the same attributes and as a result, the original relationships were maintained with both parcels after the split. The property ID of the new parcel must be updated so that each parcel has a unique value.

Once the property ID is updated the new parcel no longer has any relationships with the owners table. In order to create a relationship between the owners and the new parcel, both the owners and the parcel must be selected. In the attribute dialog box with the new parcel selected, right-click on the associated relationship class and click Add Selected to add the new relationships to the intermediate table as rows.

The next step is to open the intermediate table and update the percent ownership for the owners of the new parcel. Once the updates are complete save your edits and stop the edit session.
