I''ve been working with a new subdivision method for a couple of weeks now and thought that I''d try a do some higher frequency subdivisions to see how that worked out. I wouldn''t normally build a 6 frequency dome because I can go pretty big with the easy build 4vgeometry. It has four unique panels, none of which are scalene and can go up to 20m diameter, but I thought it would be a good exercise to see if I can build a 6v dome with as few unique panels as possible. I started with a pentakis dodecahedron took one face and put a regular hexagon smack in the middle, From here it was very straight forward to repeat aroud the sphere and then subdivide the result into a finished geodesic structure.
I''ve used this method before to produce some domes that have fewer unique panels so it''s a natural place to start with a 6v dome. The results where OK but I did think that there may be a better solution, I ended up with 7 unique panels, none scalene which is a slight improvement on the 9 unique panels using classic subdivision
A low profile dome structure would work well and give a large floor area without being too high in the centre of the dome
There is a slight lift around the base of the dome so fillets would need to be added to make the base flat, that would also be the case on the classic subdivision at the section just under the top ring of pentagons. The advantages are very similar to the 4v design, adjustable dihedral angles and a honeycombe version, I did find a layout that has only 5 unique panels but it''s going to take a while to model it as it''s not a straightforward join the dotts job like this one. Here''s a teaser, if it works out I''ll put some finished designs together.
