Hello.  
I would like to generate streamline with my CSV. file  
I have measured 3D Coordinate vector value data.  
Tell me How to make a streamline in order.

example) 3D Hexahedron vector value in CSV

X, Y, Z, Velocity\_X, Velocity\_Y, Velocity\_Z  
1, 1, 1, 0.1, 0.2, -0.1  
1, 2, 1, -0.1, 0.1, 0.2  
1, 3, 1, 0.2, 0.1, 0.3  
1, 1, 2, 0.4, -0.1, 0.2  
1, 2, 2, 0.1, -0.2, 0.1  
1, 3, 2, 0.2, -0.1, 0.2  
1, 1, 3, 0.4, -0.1, -0.2  
1, 2, 3, 0.1, -0.2, -0.1  
1, 3, 3, 0.2, -0.1, 0.1  
2, 1, 1, 0.1, 0.2, -0.1  
2, 2, 1, -0.1, 0.1, 0.2  
2, 3, 1, 0.2, 0.1, 0.3  
2, 1, 2, 0.4, -0.1, 0.2  
2, 2, 2, 0.1, -0.2, 0.1  
2, 3, 2, 0.2, -0.1, 0.2  
2, 1, 3, 0.4, -0.1, -0.2

I’m afraid you cannot generate a line from a CSV simply in ParaView. Can you store in another format ?

What file format should I save it in?

LegacyVTK format is probably the simplest.

Can you draw a streamline with a vtk file made of vectors by 3D coordinates?

You lost me there, a stream line is just a line, why do you need vectors if the streamline is already computed ?
