If you want to layout an object that would be mated on 1 mile tiles you could use this option instead of having to make each one a separate tile.
We use it when laying out large air fields for CT.
Note you should not have any objects that cross the 1 mile lines. But wrather have them mate at the boundary.
When you build the .shp file, it will create multiple shapes, one for each 1 mile cell that has objects in it.
