Drawing of plans at all nine levels of the Hall of Nations, with an overall section and elevation and also the geometry of the pyramid used as a basic module. Each plan includes two levels to help explain the pyramidical space frame geometry and how it connects to create the truncated pyramid form. The simplicity and clarity of the pyramid geometry is carried through consistently in plans, sections and elevations. The structure blooms out of twenty-four nodes at the ground level, six nodes at each face of the square plan.
