The points, as exposed to scripting, do have a position, via the
.Position property of the Point object. This position is based on the
object center. The mean by which this position is computed is, for the
sake of this problem, not relevant. So I used this position (converted
to world space) to position the nulls. I don't understand why you
mention the issue of position!

My issue was with rotation. Clearly I'm missing a piece of the picture
(as usual with vectors!)


Cheers Bernard

Vectors you can rotate just as you would any other point but scales and
transforms are different. A transform changes the direction and length of
the vector and a scale just changes it's length. The thing to remember about
vectors is that they're just directions, nothing more. Although conceptually
you think of them as having position when associated with a vertex, they
have no position at all. It's important you try and get your head around
that basic concept.
