Step 1: Add a new segment of data - indicated by blue line in graphic.

Image described in Step 1

Step 2: Adjusting the dip angle "Slider Bar" will change the view.

Image described in Step 2 - shows the added blue line changing shape

Step 3: Looking at data from below rolling back on itself.

Image described in step 3 - shows the line shaping up in a symmetrical pattern

Step 4: A repeat section develops

image described in step 4 - shows the blue line has formed opposite of where it was originally as the symmetrical opposite of itself

Step 5: The repeated section must be shifted to adjust for a small fault. The data is accepted where the curves match.

Image described in Step 5 - shows the blue line shifted slightly down to line up with the existing data shapes
