This example shows how one goes from randomly spaced data points to an evenly sampled surface with taking fault curves into account. In this sample we have 11 scattered data points to approximate (file examples/surfit/curvs/11points.txt) and 4 fault curves, which are divide whole surface domain into 3 independent subdomains. The main idea of fault curves is that parts of resulting surface between fault curve are independent of each other. Important! You should place fault rule only after fault "fault modifiable" rules!
