This command creates a 3D polyline that represents a fault line which is used by Fence Diagram in the intersection mode, or in the Make Strata Grid File command. When the fence line crosses the fault line, the strata will shift by the amount of the Z value of the fault line at that point. The Z value is the amount of elevation difference from left to right across the fault line in the direction of the line is drawn.
Pick point or point number: pick a point
Elevation difference across fault (left to right):
3.4
Number/Close/Undo/<Pick point>:

Elevation: 3.3
