4V 7/12 Assembly Diagram

The same pattern is repeated 5 times. The greyed out area represents the core triangle.

Bend angles for pipe or EMT geodesic domes can be rounded to the nearest degree

Bend angles for timber domes should be rounded to the nearest tenth of a degree (or 1 decimal point)

 

For a 4V 7/12 geodesic dome you need

30 X “A” (ends bent or cut at 6.38°)

35 X “B” (ends bent or cut at 7.46°)

80 X “C” (ends bent or cut at 8.89°)

90 X “D” (ends bent or cut at 9°)

45 X “E” (ends bent or cut at 9.35°)

40 X “F” (ends bent or cut at 9.48°)
