Select these parameters to return the coordinates of the uppermost and bottommost points of objects.
MaxY returns the maximum vertical coordinate of the object
XatMaxY returns the X-coordinate of the point having the maximum vertical coordinate
MinY returns the minimum vertical coordinate of the object
XatMinY returns the X-coordinate of the point having the minimum vertical coordinate
The coordinates are calculated in calibrated units. Note that depending on the direction of Y-axis in the current spatial scale, the uppermost point of the object could have either maximum or minimum vertical coordinate. The same applies to the bottommost point.
