How to contstrain objects, moveing on complex surfaces / HD

Hi there
in this video tutorial we’re going to learn how to make objects moving following arbitrarily complex surfaces using an appropriate combination of constraints that suits for each case.

Here’s the link to this tutorial >

Good tutorial as usual. Those directional arrows along the curve, I finally understand what they are now. Thanks.
