How to move objects that does not have a face normal to the trajectory?

[leoheck]

Hey, I am trying to use this workbench but I don't know how to make trajectories when the object doesn't have a valid face that is normal to the movement? How can I do in this case? Suppose I want to move a sphere. Is there any other way to create trajectories manually, so they could be more complex or they could be reused?
