Vectors are used everywhere in FreeCAD.

Example:

```v=FreeCAD.Vector()
v=FreeCAD.Vector(1,0,0)
v=FreeCAD.Base.Vector()
v2 = FreeCAD.Vector(3,2,-5)
v3 = v.add(v2)
print v3.Length
```

Length

Returns: returns the length of the vector.

add(Vector)

Description: adds another vector to this one

Returns: the sum of both vectors.

cross(Vector)

Description:

Returns: the crossproduct between two vectors.

distanceToLine(Vector1,Vector2)

Description:

Returns: the distance between the vector and a line between Vector1 and Vector2.

distanceToPlane(Vector1,Vector2)

Description:

Returns: the distance between the vector and a plane defined by a point and a normal.

dot(Vector)

Description:

Returns: the dot product between 2 vectors.

getAngle(Vector)

Description:

Returns: the angle in radians between 2 vectors.

multiply(Float)

Description: multiplies (scales) a vector by the given factor

Returns: nothing.

normalize( )

Description: normalizes a vector (sets its length to 1.0).

Returns: nothing.

projectToLine(Vector1,Vector2)

Description: projects the vector on a line between Vector1 and Vector2.

Returns: nothing.

projectToPlane(Vector1,Vector2)

Description: projects the vector on a plane defined by a point and a normal.

Returns: nothing.

scale(Float,Float,Float)

Description: Same as multiply but lets specify different values for x, y and z directions.

Returns: nothing.

sub(Vector)

Description: subtracts another vector from the first one.

Returns: the resulting vector.

x

Returns: the x coordinate of a vector.

y

Returns: the y coordinate of a vector.

z

Returns: the z coordinate of a vector.
