MDI Calculators are useful for quick measurements and even basic design ideas for common dome structures. An ellipse, a spherical dome, and an ellipsoid dome calculator are currently available. Common outputs include floor area, perimeter, surface area, volume plus the ability to segment the dome at a specified level. A dynamic drawing of the structure is created along with a scaled overlay to convey size. The Advanced Calculator for oblate and prolate ellipsoids is still available on monolithic.org until we finish migrating them over to the new website.
