2) Build the 12 G4Tubs sections by passing (0*degree,30*degree) for section 1, (30*degree,60*degree), for section 2, etc so that I automatically build the sections into place.

Hi,

please keep in mind that the two arguments pSPhi and pDPhi are not the start and stop angle, but the start angle and the spanning angle. In your case, you always need pDPhi = 30 * deg or your tube segments will get larger and larger, thus overlapping with each other.

Maybe this already solves a part of your question…
