How would i go about changing the height of tracks so they are elevated? I always thought you had to place them on flat ground, then dig the ground underneath so they floated.
In surveyor, you select and lay your track, then in the same open tab, you click on the advanced tool, and select the first button that has a picture of a hill and an upwards arrow. Click and lift up, and your track will rise. Two buttons below that is a ruler that is a "get vertex height" tool. You will use this and select your spline. The number next to it will change from 0.00 to the vertex height of that spline. On the right side of the number is another button that will apply that vertex height to any spline you select.
It is a really easy way to make all of your tracks the same height instead of just doing trial and error and "eyeing" things. It helped immensely when I discovered it in an online tutorial!
