45° degree ellipse

[DaSoul]

Hey guys,

i want to build a building that looks like a 3d modell of an atom.

Like this:

I was told to use worldedit to generate and rotate the ellipses that surround the core but i'm totally lost in hours of googl'ing how to do this.

Can anybode help me or give some tips?

Would be really really thankful :-)
