How to Build a 20-Foot Functional Geodesic Dome. You can download a model of our dome to use within the free. And then I’ll point you to some good calculators. Geodesic Dome Calculator DIY Dome Formula Calculator Our geodesic dome calculator will calculate the length and number of struts for 2V, 3V and 4V geodesic domes.

Geodesic 3V 4/9 Icosahedron Dome (Human is 170cm/5'7') d =, l hole = (Edit numbers & hit TAB to recalculate) • A lath = x 30,• B lath = x 40,• C lath = x 50,• h = Cut optimization: • normalize B lath+C lath = 1.0, therefore B lath+C lath = • cuts: • 40 x (B lath+C lath): • 10 x (A lath+C lath): • 10 x (A lath+A lath): • total 60 laths to cut As you see the bottom isn't entirely even, for heavy construction you have to level them. 3V 5/9 Icosahedron Dome In some literature this variant is also called '3V 5/8 Dome'. 3V 5/9 Icosahedron Dome Construction Map • edges/struts & bending angles (α strut): • A x 30: 0.34862 (10.04°)• B x 55: 0.40355 (11.64°)• C x 80: 0.41241 (11.90°)• total 165 struts (3 kinds) 1)• strut variance 18.3% • faces: 105 (3-sided) • A-A-B x 30 (54.63°, 54.63°, 70.74°)• B-C-C x 75 (58.59°, 60.70°, 60.70°)• 2 kinds of faces 2)• diameter: 2.000, radius: 1.000 • height: 1.188 or 59.38% of diameter 1) strut lengths sorted by 1/10'000th or +/-0.00005 exact 2) clock wise (cw) and counter clock wise (ccw) orientation neglected 3V 5/9 Icosahedron Dome Calculator. Geodesic 4V Icosahedron Dome (Human is 170cm/5'7') d =, l hole = (Edit numbers & hit TAB to recalculate) • A lath = x 30,• B lath = x 60,• C lath = x 30,• D lath = x 30,• E lath = x 70,• F lath = x 30,• h = Cut optimization: • normalize E lath+E lath = 1.0, therefore E lath+E lath = • cuts: • 60 x (B lath+E lath): • 5 x (E lath+E lath): • 30 x (A lath+F lath): • 30 x (C lath+D lath): • total 125 laths to cut The 4V looks very attractive, yet, I would recommend using the L3 version instead with less strut lengths and less strut variance.

Geodesic L3 Icosahedron Dome (Human is 170cm/5'7') d =, l hole = (Edit numbers & hit TAB to recalculate) • A lath = x 60,• B lath = x 60,• C lath = x 70,• D lath = x 30,• E lath = x 30,• h = Cut optimization: • normalize C lath+C lath = 1.0, therefore C lath+C lath = • cuts: • 60 x (B lath+C lath): • 5 x (C lath+C lath): • 30 x (A lath+D lath): • 30 x (A lath+E lath): • total 125 laths to cut The L3 might be a better choice for a 250 strut dome than the 4V variant: the L3 provides less strut variance 17.
