Cutoff: Horizontal Filter: Used to restrict the horizontal "reach" of the selected modeling algorithm.
If activated, RockWorks will first look at the horizontal 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 horizontal cutoff distance as a percent of the project extents.
- Map Units: Defines the horizontal cutoff distance in actual point-to-node units.
