Solved: 3D vector field

Alas_1234 · ‎12-24-2022

Hi,

I have data consist of X(x coordinate) Y(y coordinate) Z(z coordinate)

U(Vector_x) V(Vector_y) W(Vector_z)

XYZ is the coordinate of the points

UVW is the component of the vector

I try to draw leader in autocad 3d with given data like below example:

Which code I need to create vector field similar this image? Thank you.

Note: I uploaded to data as an attachment

Hello! Mr. Alas_ 1234, the relative speed of motion should be considered in this case? It is drawn according to the difference of speed in different directions. I don't know whether it is true or not，thanks！
