use BRep scripting.

### The function

### La función
44
As an example we use the follwing function to create washers:
Como un ejemplo, nosotros usamos la siguiente función para crear arandelas:
45
import Part
46
def washer1(params,document):
key = params['key']
d1 = params['d1']
d2 = params['d2']
s = params['s']
name = params['name']
47
part = document.addObject("Part::Feature",name)
outer = Part.makeCylinder(d2,s)
inner = Part.makeCylinder(d1,s)
part.Shape = outer.cut(inner).removeSplitter()
48
This function uses the CSG facilities of FreeCAD, but it is equally possible to
use BRep scripting.
Esta función usa las facilidades CSG de FreeCAD, pero es igualmente posible usar guiones con BRep.
49
It is necessary to write the function such that it is a function of two
parameters, a dict of parameter names and values, and a FreeCAD document. The
keys of this dict will be the names of the parameters of the part, as described
in the blt file. There is an additional parameter `name` that holds the name of
the part.
50
In the first part of the function, we are assigning local variables with the
parameter values as a shortcut. In the second part of the function, we add a
new object to the document, create the geometry and assign it to the part.
`removeSplitter` cleans up artifacts resulting from CSG operation under certain
circumstances.
51
### Put it to the right place
52
This function should reside in a file (in this case called `washer.py`) with
extension `.py` in a subdirectory of the freecad directory which is named after
the collection to which the part belongs (in this case `washer`). This
directory must contain a empty file called `__init__.py` and the base file for
this collection (in this case `washer.base`).
