For example, the thickness and dip of a planar layer should remain relatively constant unless the map data requires otherwise. Planar layers should also be laterally continuous unless there is evidence otherwise. Similarly, keep the structure as simple as you can. Steps to producing a cross section: I. Choose the location and direction of the profile on the geological map (usually a straight line) II. Draw or plot the topography of the profile on the cross-section III.
