General description 
Given: Surface file available in active job. It can be:
- Previously created in the Surfaces & Volumes application. See also: Create a surface step-by-step
- Imported as a reference. Refer to: Importing data to the project step-by-step
Calculate volumes to an elevation step-by step
- Open the Surfaces & Volumes app.
-
➜ To display different surfaces use Map view manager, refer to Map View manager. - Select Calculate Volume from the Toolbox.
-
- • If needed, change the value to the desired elevation.
• If needed, enter the desired offset value for the selected surface. To return to the calculation screen, tap
.The volume is recalculated according to the new elevation and displayed along with measurement data.
• If needed adapt the Expansion for Cut, Fill or both values: enter a positive (= swell) or negative (= shrink) percentage value of the calculated volume. The calculated volume is adapted immediately - Tap
at the bottom of the screen to turn on the Cut/Fill map. The icon changes to 
, in order to indicate that a Cut/Fill map is available. - Tap
to accept the result.
- In the toolbar enter a height tolerance value
for the “on-grade” green areas.
All parts within the tolerance band are displayed in green, cut or fill segments are shown matching the Cut/Fill colour indicators. By default, the tolerance value is set to 10% of the difference between the maximum Cut and the maximum Fill value. - Tap
to create the Cut/Fill lines. 
- Tap
. The "Save" screen is displayed. 
• Tap to select Cut/Fill map if you want to store the colour coded surface and the Cut/Fill lines as an XML file for further usage.
• Tap to select Flat surface if you want to store a flat, level surface at the given elevation.
By default, the file name includes the given elevation value and its distance unit.
➜ All file names can be changed according to your preferences. - To save the volume calculation, tap
. 
➜ Select Surface to Point as a volume calculation method to calculate the volume according to the height value of a specific point. For Surface to Point you can as well calculate a flat surface at the height of the selected point.
➜ Select Surface to Surface as a volume calculation method to calculate the volume between two separate surfaces. The calculated volume is based on where the two surfaces overlap.
