Vindex dome section with an axis passing through its center of symmetry.
The vindex dome is obtained by the rotation of catenary (one internal and the other external) by 180° around to their vertical axis. The distance between the two domes constitutes the wall thickness which may be constant or tapered. The dome is the most important element of Vindex Architecture.
