Hello Bernhard,

you can also use the getCrvStartFrame node as a replacement for the getBoundingBox if you use lines as your rotation axis. The advantage would be that the z-axis of the frame is always aligned to the line direction. Only difference: You have to rotate around the z-Axis. Al shows that in his example. Al: Thanks for that.

A nice day to all

p.s.: It looks like that we will have a MoI airplane to fly through our MoI worlds next time. If Ralf will bring a camera to the airplane ...
