WebAt each fold hinge, construct an axial trace that bisects the bedding dips on either side. the easiest way to do this is to add the two dips, and divide by 2; this gives the angle from vertical of the bisector. (Be careful if the dips are in opposite directions; you will need to count one as negative and the other as positive.)
