Cutoff: Vertical Filter: Used to restrict the vertical "reach" of the selected modeling algorithm.
If activated, RockWorks will first look at the vertical proximity of control points as it's interpolating a node's value. If there are no control points within the defined distance, the node will be assigned the Undefined Node value.
- Percent of Project Size: Defines the vertical cutoff distance as a percent of the project extents.
- Map Units: Defines the vertical cutoff distance in actual point-to-node units.
