Excellent dome calculator!


I have been studying geodesics for more than 25 years, majored in Design Science, and live in a geodesic dome. I know dome stuff. ;-)

This is an excellent tool for calculating geodesic geometries, with a colorful and intuitive interface, that lets you easily design a dome based on either octahedral or icosohedral geometries, and up to nine frequency complexity.

It also lets you take a "slice" of your dome, so that you can create various portions of a full severe, depending on your needs. And when you are satisfied, and have given it the height and/or diameter that you wish, it will calculate all the piece lengths, in either English or metric units, and give you a helpful color-coded assembly diagram.

Honestly, this thing covers all the bases in a very easy to use format. It even lets you save dome geometries of your favorite domes. (Though I have not figured out how to delete saved domes, yet.)

Whether you are a geometry and dome fiend like I am, or someone just trying to plan out a dome for Burning Man, this tool will help you. Highly recommended!

Takes the guesswork out of the picture. I really like the scaling feature to determine most efficient use of material length for the struts, as well as the color coded strut feature. In general, it's fun to play around with the various dome frequencies. Love it!

Lost some features !


Previous version let the user rotate the dome with finger movement on screen. New version only rotates with tilting of the device. Not as convenient. Display is also filled panels and only shows 2D wire image for assembly diagram. Both of these should be user selectable. But then, it's free.
