"""Create an orthogonal array from the given object.
Parameters
----------
obj: Part::Feature
Any type of object that has a `Part::TopoShape`
that can be duplicated.
This means most 2D and 3D objects produced
with any workbench.
v_x, v_y, v_z: Base::Vector3, optional
The vector indicating the vector displacement between two elements
in the specified orthogonal direction X, Y, Z.
By default:
::
v_x = App.Vector(10, 0, 0)
v_y = App.Vector(0, 10, 0)
v_z = App.Vector(0, 0, 10)
Given that this is a vectorial displacement
the next object can appear displaced in one, two or three axes
at the same time.
For example
::
v_x = App.Vector(10, 5, 0)
means that the next element in the X direction will be displaced
10 mm in X, 5 mm in Y, and 0 mm in Z.
A traditional "rectangular" array is obtained when
the displacement vector only has its corresponding component,
like in the default case.
If these values are entered as single numbers instead
of vectors, the single value is expanded into a vector
of the corresponding direction, and the other components are assumed
to be zero.
For example
::
v_x = 15
v_y = 10
v_z = 1
becomes
::
v_x = App.Vector(15, 0, 0)
v_y = App.Vector(0, 10, 0)
v_z = App.Vector(0, 0, 1)
n_x, n_y, n_z: int, optional
The number of copies in the specified orthogonal direction X, Y, Z.
This number includes the original object, therefore, it must be
at least 1.
The values of `n_x` and `n_y` default to 2,
while `n_z` defaults to 1.
This means the array by default is a planar array.
use_link: bool, optional
It defaults to `True`.
If it is `True` the produced copies are not `Part::TopoShape` copies,
but rather `App::Link` objects.
The Links repeat the shape of the original `obj` exactly,
and therefore the resulting array is more memory efficient.
Also, when `use_link` is `True`, the `Fuse` property
of the resulting array does not work; the array doesn't
contain separate shapes, it only has the original shape repeated
many times, so there is nothing to fuse together.
If `use_link` is `False` the original shape is copied many times.
In this case the `Fuse` property is able to fuse
all copies into a single object, if they touch each other.
Returns
-------
Part::FeaturePython
A scripted object with `Proxy.Type='Array'`.
Its `Shape` is a compound of the copies of the original object.
