Yellow Circles vs White Cicles

[Eaglefan9727]

Hi there -

In the picture below. I have a yellow cicle and a white cicle. Can you tell me why there is a diffrence between the two? Is it, Because there is something wrong with the track at the white circle area? Thanks

Hmm, the yellow circles have a fixed spline height, the white ones don't.
This means that the yellow ones will be fixed in place when you alter the terrain height (preferred), the white ones will change height according to height changes you make in the terrain after laying the track. This can of course create much too steep grades, so it's better to use the fixed spline height. There's an option in the Suveyor settings (use main menu / options / surveyor) "Use fixed spline height" where you can set a checkmark to make this the default setting when laying tracks.
