Thank you very much for your help.

I did stumble across this method last night myself after posting and it works great if the arrow shapt is confined to a single plane; however, I have the shaft making a 90 degree on one axis and the a 50 degree bend on an orthogonal axis. This seems to produce very unpredictable behavior for the orientation of the arrow head as it tries to maintain a tangential orientation with respect to the spline path. Would a rail spline help?

Apparently there is a way to do this with xpresso and bend deformers? The bend deformer method seems to make orienting the arrow head easier when animating through orthogonal planes.

Thanks again for the help.

Regards,
Andrew
