Elevator help

How would I make an elevator?

I know how to do it, but what’s the most efficient, easiest way to do it?

I’m using an elevator prop, by the way.

Parent to invisible brush which is func_tracktrain or func_movelinear, depends on if it’s two-stop or multiple-stop elevator.

It’s tricky to get perfect, but I like func_tracktrain and func_train best.
