When building a route - is there a way to sort of "merge" the spline points for different types of assets? For example. I've laid my track, no I want to go back and add spline scenery of the 3rd rail. This obviously needs to follow my track exactly...so is there a way to merge the points, so as I click my track points the 3rd rail would sort of join with it? I hope that question is clear, I couldn't really find a good way to explain it. Thanks in advance - and happy holidays!
