More specificly I want to demonstrate a curved arrow in 3D.
I understand that using Curve3D can give me a list of points on the curve, and also there are other ways to describe the curve itself.
But I just don’t understande how to put it into the 3D scene with thickness

You have to turn it to a mesh first. For your specific case using a CSGPolygon is the easiest way. Add a CSGPolygon to your scene and a Path3D. Set the mode of the CSGPolygon to path and path node to the Path3D and adjust the parameters (including the thickness) to your liking.
