Calculating the correct angle needed to bend a plane into a "cylinder shape" Calculating the correct angle needed to bend a plane into a &quot;cylinder shape&quot;.
I have a 5x5 diamond plane that when I bend it 396 degrees it becomes a &quot;cylinder shape&quot;

Another diamond grid 15x15 requires 372 degrees for it to close.

How can I calculate the angle (using a formula) I would need to bend other diamond planes into a &quot;cylinder shape&quot;
It is just linear, it seems

If it is for N diamonds in the line above, then the angle is:
360 * (1 + 1 / (2 * N))

as we need to fill one half one diamond plus these N.
Or to say it another way, this is the ratio of the size considering the half diamond by the size without it x the angle.
