The form was a big truncated cone. The secondary assembly was an elongated truncated cone. The shield was a truncated cone containing lithium hydride. The nucleoids are concentric and rod-shaped, or shaped like a truncated cone. The cap is of a truncated cone shape and is covered by thatch. The building resembles a truncated cone capped with a geodesic dome. Each section was shaped like a truncated cone which gave the craft a conical shape. A conoid is found in most species and when present forms complete but truncated cone. The upper section, which contained the experiment package, was shaped like a truncated cone. Its cavity is also asymmetric, but relatively flat rather than a truncated cone.
