Open the Expression Editor based upon the desired use for the expression. See
Use Expressions for more information on different types of expressions.
Select a location condition from the
Spatial category options in the Expression Elements menu.
Note: You can specify
Disjoint,
Intersects,
Overlaps,
Inside, or

About Filtering By Location for more information.
In the model, click once to specify the center of the location condition area.
For rectangular and polygonal areas, click again to place each additional boundary point.
For a circular area, move your cursor away from the center of the location point to increase the diameter.
Double-click to finish the location condition area and return to the Expression Editor dialog box. The location condition for the area you specified is inserted into the Expression Area.
Note: Do not edit the location condition in the Expression Area. Directly editing the location condition may invalidate the expression. Instead, delete the location condition from the expression and re-draw the spatial location condition.
