| An elliptical 4v dome would be a daunting project. As you mention 5/8, i presume it needs to be more than half a sphere? As a guide to the complexity of your project.. a standard (non-elliptical) 4v 7/12 uses 310 struts with 13 different lengths and 110 hubs with 12 different types. | |

I agree with Colin, that's one complex concept. I can build an eliptical 4v dome on my computer, take a look at the picture below. It is possible to workout from a 3d drawing all the measurments you will need but it would take ages. If you can make use of a 3d drawing I can post a .dfx file.  |

| Hi Paul, I wouldn`t want to take on a project like that and i`m a glutton for punishment hehe. Thats a nice rendering of a 4v elliptical dome. If it doesn`t look challenging enough..imagine an extra row of triangles on the bottom :) | |
