The intention of my question is that the initial position and orientation of AnySeg are determined by its ‘r0’ and ‘Axes0’ properties.

Besides drivers and constraints, I should think that the initial position and orientation of all AnySeg objects should represent their ‘r0’ and ‘Axes0’ values.

As I told in my first post, some Axes0 values like this may not work properly:
“Axes0={ {-1, 0, 0}, {0, 0, 1}, {0, 1, 0} };”

This means that initially the local x-axis of this AnySeg should be represented as (-1, 0, 0) with respect to the global coordinate system. And the local y-axis should be (0,0,1) and the local z-axis should be (0, 1, 0). But this may not work.

Thanks for your reply and I hope to get your additional help.
