Hi Pilou,

re:

Yup, the regular Orient command does as well. But from what I understood it was not just any point on the sphere that was wanted, it was one that was lined up with the world y axis.

The other problem with Line/Line is it can introduce unpredictable rotations if the base line and target line are not all on the same plane. But with a cylinder it doesn't really matter if it rotates around its own axis line.
