Let's see if I can understand what is going on here.

I first need to determine the axis that is perpendicular to the plane formed
by the two vectors using:

#declare Axis = VPerp_To_Plane(<X4,Y4,Z4>, <-15000,75,2435>);

Then I need to determine the angle on this axis that would point from
<X4,Y4,Z4> to  <-15000,75,2435> using:

#declare Angle = VAngleD(<X4,Y4,Z4>, <-15000,75,2435>)

And finally I need to perform the rotation

Axis_Rotate_Trans(Axis, Angle)


Still not getting the proper results...You are right I am missing something
completely here.


I tried

VRotation(<X4,Y4,Z4>, <-15000,75,2435>, Axis)

but still I don't get the expected results

Help!
