CHAPTER 7 "CARGOES" 43 In the Load field give a characteristic name for the load. You are then prompted to specify how the loads are to be distributed on the selected surface. The definition can be done graphically: • With its 4 vertices and the corresponding values of the load. • With any 3 points of which the first two define a line where one value of the load will be applied and the third point the altitude where the other value will be applied. The points may not be coplanar and its outline may include lines, arcs and circles.
