Hi,
How accurate are your angles on the connectors? There are two types of Geodesic
Dome/Sphere methods. Those that are calculated and actually touch the inside of
a sphere. Great but you end up with MANY different lengths of connector rods. Or
there is the type that Buckminster Fuller designed that uses only three different
rod lengths that is extremely close to a sphere but some touch, some are a little
inside and some are a little outside the sphere. Method 1 is basically a custom
design that is hard to scale. Method two is absolutely scaleable as long as the
angles are correct and the ratio of the rods are exact. You should be able to scale
a 2V at an Order of Magnitude for each Decimal Place. I.E. 1M sphere - 1 decimal;
10m sphere - 2 decimals; 100m sphere - 3 decimals; the size of the earth - apparently
only 6 decimals but I haven't checked that. It wouldn't surprise me as you only need
six decimals to work out the radius of the Universe to within 18 inches. (Trivia I have
picked up somewhere).
When I first started on this Forum I had a long discussion about this. Do a search and
there is some very good resources linked to it. I was VERY new, it may have been my
first post.
When I attempted this project manually on AutoCAD I made Pentagonal assemblies
and then joined them together one by one and then filled in the Hexagonal assemblies
which is what you should get with a 2V.
A few comments.

You have too many Move commands. Do NOT use Move unless you THOUROUGHLY
understand what it does and when and why to use it. Move Bites the unwary in
Fusion. It is NOT a simple tool for moving things around.
While it looks very pretty, unless you are going to do a Combine Command at the
end of the exercise all of those bodies are simply floating in space and are NOT
joined at all. You can click and drag every one unless you have Rigid Groups. This
design in its present form would be useless if you actually wanted to fabricate it.
You need to have Components to make Joints that will join everything together.
To do this properly you will need two types of connector Components and three
types of rod Components as your basics. You then create an Assembly and copy
each of the Components you need into the Assembly and Join everything up into
a Hexagonal and a Pentagonal basic Assembly. You then copy these assemblies
and use Joints to connect them together and build your Sphere. You "could" use
Circular Pattern if you wanted but you only need a rod and two Joints to connect
the Hex and Pent Assemblies and it is straight forward.
All of those Axes look pretty and would have taken quite some time to create and
set up. You don't actually need any of them. If your connectors are accurate and
you use Joints then the sphere will build itself.
If you know some of the rods are off then some of your problem is here. Done correctly
a Geodesic object is a precision structure. It is very strong and very forgiving from a
structural sense but it needs to be accurate to work properly.
