I'm having trouble with the Generate Tessellation GP tool in Pro 2.0.  I can't get it to create the correct sized polygons. 



I created a new Pro project and added our County boundary polygon, in State Plane, feet. I verified that the Map Frame coordinate system is in feet.MapFrameUnits


I generated a tessellation using the extent of the County boundary and specifying a size of 1 square mile.

The output is NOT a set of polygons with area=1 sq mile, but rather area= 0.092903 sq miles (2589988.8 sq feet). This is the consistent area of the polygons in the result whether I generate square or hex polygons.

 Any ideas?
