The 3D truss calculator determines the truss element loads given the user input loads and boundary
conditions at the applicable nodes. The truss elements have pinned connections and therefore, do not
carry or transmit moments. The chart shows both the unloaded and loaded configurations as well as
the input loads and global X,Y,Z axes. The deflected shape can be user scaled and the configuration
user rotated about the 3 global axes. The compressive loaded elements are compared against the
theoretical Euler buckling load.
