Catalogs of basic geodesic geometry • Each catalog contains several dome or sphere 'components' • Any of these individual components can be copied from a catalog model and pasted into a new model of your own creation • Dome and sphere components are of unit (1 foot) radius, to provide chord factors • Domes and spheres can be scaled up to the size you need • After resizing, full-size strut (chord) lengths can be measured/displayed
