Hi, and thanks for any help. The object is a capsule shaped polygon. So far, I've got the object and a helical spline with a tag for spline tracking>helical path. I also need the capsule to have a rotation along it's longitudinal axis while traveling longways along the helical path. Except for the helical path, very similar to an American football being passed with perfect spiral along an arc with the nose of the football following the trajectory, first tilting up, then gradually pointing down as it descends. I can rotate the object and follow the helix OK, but the problem I'm having is that the capsule's rotation seems to be limited to setting on either x,y,z axis and seems locked there without staying square to the ever changing axis of the helical path. Hope this makes sense? Thanks for any ideas!

Maybe like so?

A simple rotation value keyframed along the Z-axis will do.

That's too obvious.A simple rotation value keyframed along the Z-axis will do.

Hi Frank, that is exactly the result I'm looking for but my capsule is still going sideways instead of longways like yours'. I tried to duplicate zooheads' file w/ the rail object but couldn't make it work, still missing something. Sorry, could you take another look please? / thanks, John
Kill the Rail-spline, add a Transform-modifier to the Capsule and set the P(itch) value to -90° to align it to the Z-axis.
