Allows you to calculate the chords, radius, diameter, and node positions for any class 1 geodesic sphere of any frequency. The program provides chord, radius, diameter, and node location data in cartesian coordinates for a geodesic sphere or dome. You are prompted to select a polyhedron type, a frequency, and a basis for sizing the sphere. Information is only given for one typical triangle which is representative of all other triangles on the sphere. In addition, the results are automatically displayed on the screen.
