How can I get a CFrame along a BEAM?

I have a way of getting the position along a beam with a scale of 0 to 1, but I also need the rotation as well, basically a whole CFrame. How do I do that? I’m assuming it still has to do with the bezier curve but idk how to do that math.

What do you mean you need rotation? Mind drawing a sketch?

Like twisting an stuff
