Apply Filters to Data Selection
Apply one of more filters on your data.
Before being able to activate the filter button, you must first select a variable from the list in the Data Explorer panel. You can select multiple variables by holding down the control key while clicking with your mouse.
Generic Filter Options
On the Filter tab, click on Filter to open the Filter panel. The Generic filter options will be displayed first.
New Filter
General / Copy Filter / Delete Filter
| General |
Select the type of filter to create.

| Copy Filter |
Click this button to create a new filter using all the parameters of the current filter that is in focus. |
| Delete Filter |
Click this button to delete the current filter that is in focus. Warning! This operation cannot be undone! |
Data Source(s)
Select the data source from the drop-down list.
Filter Name
Enter a name for the filter. The name you select will become part of the name displayed in the charts produced. There are no character restrictions. As you type a name, it will be display in the side panel on the left side.
The column of filter names will always be visible while you are editing in the filter panel. When a filter is first created the name is highlighted in red, indicating that there is still something that needs to be done before the filter is ready to be saved.
While a filter is highlighted in red, the OK button will not be in focus and you will not be able to click it to save any changes.
General Filter Options
Use Range
Select this option if you wish to use a range of values, then enter the minimum and maximum values.
Field
Select the field from the data source that you want to apply the filter to.
Bounding triangulation
Select this option to restrict the blocks by a triangulation. You will be required to specify the bounding triangulation.
This option is not applicable to open or 2D triangulations.
Condition
Select this option to use a further constraint upon a numeric variable, for example Fe GT 10.0 (iron value greater than 10.0). The maximum size of a condition statement is 132 alphanumeric characters. A list of available operators/functions is provided in Appendix B of the Core Documentation.
Use $v for Target Variable
In the conditional statement you can substitute $v for the actual name of the variable. The $v will replace the variable selected from the dropdown list above in the expression. This is useful to review multiple variables without rewriting the condition statement each time.
Samples Filter Options
Sample Group
Enter the name of the sample group or a wildcard character (*).
Numeric Filter
Select this option to use a numeric filter.
Field
Select the field from the database that you want to apply the filter to.
Use Specific Values
Select this option if you wish to include or exclude specific values.
Use Range
Select this option if you wish to use a range of values, then enter the minimum and maximum values.
Solid Triangulation Filter
Select this option to limit the data by triangulation.
Adding triangulations
To add triangulations, click the drop-down list to select triangulations that are found within your working folder or click the Browse button to select triangulations that may be found in other folders.
Deleting triangulations
To delete triangulations, first click in the row to highlight it, then hit the Delete key on your keyboard.
Character Filter
Select this option to limit the data by character.
Field
Select this option to use a character field from the database.
Use Specific Values
Select this option if you wish to include or exclude specific values.
Field Restriction Filter
Select this checkbox to limit the samples to those with fields that match certain selection criteria. Select a Field from the drop-down list and enter applicable selection criteria in the Attributes column.
Include spaces in the entries in the Attributes column only if spaces are included in the desired field values.
When entering a range, always enter the smallest number specified before the largest number.
Example: -792&-720 since -792 is smaller than -720. This range is evaluated as -792.0 ≤ VALUE < -720.0.
The range entered must always have the smallest number specified before the largest number, for example, -792&-720 , since -792 is smaller than -720.
Block Model Filter Options
Variable
Select this option if you want to restrict the blocks by a variable. You will need to specify a particular value.
To restrict blocks to those where Material equals Ore, select Material as the variable (from the drop-down list) and enter Ore as the value. However, if you require all blocks that do not have this specified value, then enable the Reverse matching check box found at the bottom of the panel. The block model variable may be numeric (for example a grade variable such as Au) or character (for example Geology).
Condition
Select this option to use a further constraint upon a numeric variable, for example Fe GT 10.0 (iron value greater than 10.0). The maximum size of a condition statement is 132 alphanumeric characters. A list of available operators/functions is provided in Appendix B of the Core Documentation.
Use $v for Target Variable
In the conditional statement you can substitute $v for the actual name of the variable. The $v will replace the variable selected from the dropdown list above in the expression. This is useful to review multiple variables without rewriting the condition statement each time.
Bounding triangulation
Select this option to restrict the blocks by a triangulation. You will be required to specify the bounding triangulation.
This option is not applicable to open or 2D triangulations.
Use selection plane
Select this option to define a selection of blocks by plane.
Thickness
Enter the thickness of the plane.
Orientation
Use the drop-down list to select either Easting, Northing, or Elevation, and then enter the coordinates.
Use bounding surfaces
Select this option to restrict the blocks by bounding surfaces. You will be required to select the upper (top) and lower (bottom) surface triangulations.
Use bounding box
Select this option to restrict the blocks by a box. You will be required to enter the minimum and maximum X, Y and Z values in either model coordinates or real world coordinates.
Reverse matching
Select this option to exclude (not display) the selected blocks. This option works in combination with the other options on this panel. For example, if you set up Variable to display all blocks that have a gold grade of (-99.0), selecting the Reverse matching option will prevent any block with a gold grade of (-99.0) from being displayed. Or as another example, if you set up a bounding box to limit Z values between 2300m and 5500m, selecting the Reverse matching option will prevent blocks with Z values between those elevations from being displayed and show blocks with all other Z values.
