i'm new. I want to build a street, which follows a curve. The street has a 270° curve with gradient. Here a picture to illustrate it: enter image description here

The picture show also my problem. The street rotates on the second end.

How can i avoid this effect?

  • $\begingroup$ Realize though, that a road must have camber while it is both changing direction and altitude. In other words, it can only be laterally level over a section in which it's direction doesn't change no matter how short that section is. $\endgroup$ – user29520 Aug 15 '16 at 22:13
  • $\begingroup$ Also note, not even dragging vertices by hand will change the fact that it is a topological impossibility to create a ribbon that remains laterally level while it is climbing and changing direction. $\endgroup$ – user29520 Aug 17 '16 at 6:21

You can twist the curve points using Ctrl+T :

Or you can use the Z up curve option :

  • $\begingroup$ You can also adjust the twist at each control point using the Mean Tilt value in the Transforms panel. $\endgroup$ – Anthony Forwood Aug 13 '16 at 21:00
