Keeping local X-Axis from rotating, while moving up and down on a Curve

Question

I made a Geometry Node, which transforms a given Curve into a street. While the curve has the same value vor Z, it looks fine (Picture 1). When I start playing with the Z values tho, the road starts rotating inward. How can I keep it from doing that? Basically, I want the Normals local X Value 0.

If possible, I want to solve that in Geo Nodes.

Thanks in advance :D

Set Twist method to Z-Up in curve properties:

And you can use set curve normal in geometry nodes:

This is what I was looking for, thanks. Is there a way, to do that in geometry nodes tho? – Kralkaz -.- Mar 16 '22 at 10:13

I haven't found – Crantisz Mar 16 '22 at 10:16
@Kralkaz-.- Before the Curve to Mesh node add in a Set Curve Tilt node with 0°, this should reset all tilting in the curve. But additionally use the Twist Method > Z-Up in the Curve Properties as well. – Gordon Brinkmann Mar 16 '22 at 11:07
