Is can be common to have a design which has specific cut slopes for the various Strata in a cutting.
If you report volumes from the Design to a Strata Surface the volumes reported can be incorrect, this is due to the design being above the strata surface leading to additional Fill volume being reported.
The image below show an example of the volumes reported between the Design (Yellow line) and Strata 4.The Cut area in Orange is the only required volume and the Fill areas in Bright blue aren't required.
The steps below detail how to report the correct volumes for multi strata cuttings.
