Properties
If you want to display one or calculated averages for the block model, select one of the options on the Properties tab.
If you select All fields, the calculated averages for all fields will be displayed. Conversely, no calculated averages will be displayed for any fields if you select No fields.
If you select Custom, you can configure the fields for which you want calculated averages displayed using the grid. You can use the tools for the grid to Manage the rows in the list and add each field required.
The fields selected in the Properties tab will be displayed in the Average grid of the Properties panel for the block model.
