Returns the true angle in degrees from vector v1 to vector v2 in 3-space. A third "normal" vector v3 is used to determine the direction of measurement, using the right-hand rule. Negative angles are not returned.

v2 As Vector, _
v3 As Vector ) As Number
| Argument | Type | Description |
|---|---|---|
| v1 | Vector | start vector |
| v2 | Vector | end vector |
| v3 | Vector | A vector , not in the plane formed by v1 and v2, used to pick between the two choices for angle. |
Intent >angle2Vectors(Vector(1,0,0), Vector(0,1,0), Vector(0,0,1)) --> 90
Intent >angle2Vectors(Vector(1,0,0), Vector(0,1,0), Vector(0,0,-1)) --> 270By reversing the bias vector , we obtain the other interpretation of the angle.
