Testing this further, I find that there is a conversion bug or a writing to
POV-Ray bug. The output should be:
<0.916469,74.4353,2.32733>,0.1
instead of:
<0.916469,74.4353,2.32733>,0,1
In addition, the sweep thickness values for the root and tip diameters are
not converted correctly, probably as a result of the above. Whatever changes
are given, the result always remains <vector>,0,1
