Hi,

Another question. I see some route pics that have steep banks next to tracks. My question is how do you generate this without making the track bed move with it?

Thanks
 
Hi Robby, this can be done if you run the track bed parallel to one of the grid lines and then move one whole square away from your track bed and then raise the gound ie think of your track as running along row of squares one, ignore row of squares two and then raise the squares at row three, this will pull one side of row 2 up with it but leave the track side at track datum level.

Hope this helps, Andy
 
In the pic below it shows there is a cement wall with the ground level to the top of it behind. If I was to try and do this, when raising the ground behind the wall it would also raise the ground under the wall thus shifting the wall. What am I missing?

This is often done with retaining wall splines which have "ground" attached at the top. The actual ground then rises gradually behind the wall to the correct level.
Try a search for retaining walls on the dls, but there are a lot of them so beware!
 
I don't know if this is relevant to your question, but you need to use the "spline height adjust" tool so that the spline circles turn yellow. If the spline circles are white (before they have been adjusted) the object will go up and down with the terrain.
However, it seems that even after the spline circles are yellow, objects will still move slightly when the terrain is raised or lowered. I suspect this is a minor bug in Surveyor, but it can get quite annoying, as you are constantly having to re-adjust things.

In TRS2006 theres a useful builtin tool called Hole Punch which makes the ground invisible.In this situation on my route theres a road with the railway at a higher level supported by a retaining wall made of Stone Retaining Wall Dirty.To overcome the difference in height I have set the rail trackbed to the right height then punched holes and laid the road over the holes.The ground is still there but you can"t see it.The advantage of this method is that you can paint the higher level ground any colour, since you don't have to use a retaining wall with ground attached..:cool:

further to this....

If the ground under where you place the ret wall isn't straight then the wall follows the ground and thus is not straight...

How did they get by this on this? Make sure the ground is all level all along it??
