Etape pour dessiner un noeud d'autoroute en 3D

[PauleSud]

Bonjour, j'ai très peu de connaissances en 3D sur vectorworks. J'aimerais recréer des courbes en plan ainsi qu'en coupe afin de dessiner un noeud d'autoroute en 3D, mais je ne sais pas quelles sont les étapes les plus simples pour ce faire. Est-ce que quelqu'un pourrait aurait une idée ?  Merci d'avance pour vos réponses

Hello, I have very little knowledge of 3D on vectorworks. I would like to recreate curves in plan as well as in cut in order to draw a 3D highway knot, but I don't know what are the simplest steps to do this. Could someone have an idea?? Thank you in advance for your answers

Anyone with more experience want to take a crack at this? If not, I will try to explain NURBS Curves and Lofting.

Ooops,

VW may not be the most suitable and comfortable Software to do such things.

But I also think it would be possible.

I would also tend to using :

Thank you for your answers ! I could finally do it on an other software that was more suitable for that kind of manipulation !

You also have sweep and exude along path as options both let you use the same profile. 

But having played too much cities skylines I'd suspect Vectorworks (or skylines) aren't the best tools for it.
