Yes, you are right. i tried it. I studied the geometry and realized exactly what you said, the fact that i am breaking up into 9v the hexagons become slightly skewed on 2 axis because they are no longer symmetrical like the hexagon that ends up in the very center of where i divided everything from.
The pentagon is how i thought the ball got its round shape, and why you can’t have a soccer ball without the pentagons and hexagons. But there is a way to have flat panels on a dome, it is called a geodesic dome. It is not real hard drawing 9v geo dome using triangles instead of trying to have the hexagons without the 6 inner triangles inside as the structure, because then you can break up the hexagon into 6 pieces, and therefore can be skewed a little. From just 3 points, you can have a flat panel much easier, no matter what angle. Just 3 points anywhere in space, each point could be anywhere, but connected will make a flat plane, but add any more and ■■■■ can hit the fan if you don’t have the math worked out.
