The software allows users to define prismatic and tapered beams. The default profile is made from one segment with the same section at each end. More segments can be added to the beam profile by adding more sections along the beam. A typical case of the need to change the section at one end, or add more sections is tapered beams. The cross sections at each end of a tapered beam must be defined by dimensions. Only the depth of the beam can be varied in a tapered beam.  The changes made to the profile table are applied and the graphics are refreshed when the user clicks on the Save button.
