Calculate Fault Shift

This command assigns fault shifts to polylines. The polylines must be drawn ahead of time and they should follow the fault zones. After selecting the polylines to process, the program prompts for drillholes to process. Then select a strata to model. The fault shift is calculated by modeling the strata twice for each polyline. One model excludes the drillholes on the left of the polyline and the other model excludes the drillholes on the right. Then the elevation difference between the two models is used to assign the fault shifts along the polyline.
