Auto Balance Volumes

[Nik-D]

Hi all

I have a surface which I created from a closed loop Feature Line. I did this because it was easier to adjust the elevations around the edge in nice smooth grades to produce a finished edge profile. I assigned the Feature Line to its own Site and created a Grading Infill which is also in the same Site. When I go to the Grading Volume Editor it allows me to select Entire Site and calculates volumes but it does not adjust the levels of the Feature Lines automatically. Why, as I have done this previously.

Thanks in advance for any light shed on this.
