Site Designer for Revit 2017 - Curved street problem

[bro]

I'm trying to create a curved street, but somehow the terrain doesn't follow the curve. It just cuts through straight and lies partly on top of the street.

Here is an example with a very basic terrain I created:

See what I mean? I aware that I can't use the family manager from the Site Designer toolbar inside Revit, but I have to open the rfa family file and edit the parameters there.

It's just too much work to adjust each of the terrain points manually. How can I make the terrain follow the street when it's curved like the shown example - please help.

The topography must be edited to meet the required level. When it comes to terrain-specific features, it is more often required to create a point-by-point layer, when in a slope, sloping curve or irregular terrain.

The article to refer to creating Topography can be accessed by clicking >HERE<. May it help answer your questions.

Thanks for the reply.

I've made a comparison with Revit 2016, with editing points on the topography:

And here is the exact same model in Revit 2017, so something seems to be wrong with the software:

Any ideas?
