There are three different modes to visualize the selected Drillhole Attributes based on radius, selectable via a dropdown menu in the Drillhole Inspector:

• Constant: The drillhole is rendered with a constant radius. The radius can be manually set in the Radius field.
• Interpolated: The radius of the drillhole varies based on the value of the selected attribute. Minimum and maximum values of the radius correspond to the minimum and maximum values of the attribute. Where no data is available along the drillhole, the radius is interpolated from surrounding data points along the drillhole.
• Discs: The radius of the drillhole varies based on the value of the selected attribute. Minimum and maximum values of the radius correspond to the minimum and maximum values of the attribute. Discs are displayed only at points where data is available along the drillhole, without interpolation.
