# User Parameters

You define user parameters to model parameters that are not derived from the geological models. Parameters that are not derived from the geological model include numeric parameters, such as cost factors, and text parameters, such as heading types.

You use numeric user parameters in User Calculations, where a constant value cannot be used in the user calculation because the value of the parameter changes by location or changes over time. This allows you to set up the schedule to calculate, target, and report on values that do not originate from your geological models.

Numeric parameter values can be displayed in Dashboard reports and output to standard and custom reports.

You use text user parameters in Visibility Constraints in the 3D Canvas. For example, you use text parameters to constrain the 3D Canvas to divide a large mine into discrete zones to allow you work on each zone separately when setting up the schedule.

You can also filter Dashboard charts and reports using text parameter values, and group the Dashboard Gantt chart by text parameter values. Text parameter values can be output to standard reports, databases output and Microsoft Project output, allowing you to group by text parameter in these downstream applications.

### Columns in the User Parameters Data Grid

Column | Description
--- | ---
Name | The name for the parameter. Note: The name is case-sensitive and cannot contain spaces.
Type | The type of parameter. Options are: Numeric: Parameters that are used in mathematical expressions. Numeric parameters can be weighted by Mass, Volume, or Length. Text: Parameters that are used as descriptions for headings and locations. Note: Text parameters cannot be weighted.
Weight by | The method used to determine how a numeric parameter value is calculated when reporting from multiple locations, where the parameter value varies by location. Options are: Mass: The parameter is weighted by mass. Volume: The parameter is weighted by volume. Length: The parameter is weighted by length.
Background value | The background value for the parameter. The background value is used for any location or heading for which no specific parameter value is assigned in the scenario. Notes: User parameter values for development headings are assigned in the Setup Development > Parameters tab. You can change numeric parameter values along a heading. User parameter values for underground production locations are assigned in the 3D Canvas of the Setup Schedule > Locations tab. User parameter values for surface production locations are assigned in Parameters data grid in the Setup Schedule > Parameters tab. You can change numeric parameter values over time, in both surface and underground production locations.
