If you run the Calculate Volume command using the command-line options Multiple or All, the following window appears:
This process has two modes of operation when applying the parameters involved in the calculation:
Specific to Each Zone: if the volume in the selected zones has been previously calculated separately, this mode allows the calculation to be recalculated with the previously used parameters. In this way, a larger cell size could be used over very large zones, to speed up the calculation. Conversely, in a certain zone you could decide to use higher clearance tolerances.
Common to AllZones: This mode allows you to calculate all selected zones uniformly with the same parameters. If the Overwrite Zone Parameters option is enabled, the values entered here will be assigned to the zones, replacing the previous parameters. Disabling the latter option allows you to quickly calculate alternative scenarios, for example with larger tolerances.
Once the calculation is done, a list of the results appears on the screen.
