There is no 3D equivalent of Arrow; however, I have written a small routine
called Vector3D[{x1,y1,z1},{x2,y2,z2},HeadLength] that draws a line and an
inverted cone for the head of the vector. It works, but I usually have to
fiddle with the size of the cone through HeadLength to make it look right.
If you would like, I will send it to you.
