If you can get the points for one section, you might use LDScript (or
most any programming language) to generate the other sections, coding it
to reuse the end-points from one section as the start-points in another
section (instead of just rotating the previous start points into the new
start points, and hoping they match up exactly with the previous
end-points).
The lathing tool in LDAO (which is limited to lathing polylines, and
can't be used to help you out) is coded to use reflection where possible
to generate points. For example, in a 'standard' 16-segment circular
rotation, the lathe-er figures out the points at the 22.5-degree
rotation, then it calculates the points for the (complementary)
67.5-degree rotation by copying the 22.5 points, and swapping X and Z.
Likewise, for the other X-Z quadrants, the points are derived from the
1st quadrant points.
