using-and-improving-surface-models-built-by-computer_fig13.png|{{figure number|13}}Separate surface models are built for each fault block. (a, b, and c) The surface for each fault block is allowed to extend past faults defining the block edge. (d) When displayed, contours are constrained to inside the fault block polygon and all models are displayed on the same map. (After <ref name=pt08r11 />.)

using-and-improving-surface-models-built-by-computer_fig14.png|{{figure number|14}}Surface models are constructed for the faults and for each surface on each side of each fault. Operations between surface models prevent them from projecting past one another.

using-and-improving-surface-models-built-by-computer_fig15.png|{{figure number|15}}Faults act as barriers beyond which data cannot be seen from the location for which a surface value is being calculated. (a) A grid node (indicated by +) to the west of fault A can only see data in the hatchured area. (b) A grid node farther to the south of fault A can see more data, thus the surface smoothly changes form around the fault ends.<ref name=pt08r11 />
