How do the Curve.Normal and Curve.NormalAtParameter nodes calculate the direction of normals?

Hey,

You might find this useful in visualising how vectors are working…

How to get vector perpendicular to curve?

See if this helps, credit to @Marcello_Sgambelluri, visualising vector direction… [image] Edit: Maybe this works for you? [image]

Perhaps someone else can explain the code behind it, personally I tend to play and see how it works, but it is always useful to understand the logic

Cheers,

Mark
