from pyooml import *

Create a document:

doc = App.newDocument("Example")
doc.recompute()

Call pyooml.cube:

cube(10,10,10)
Traceback (most recent call last):
File "", line 1, in
File "pyooml.py", line 434, in init
super(cube, self).init(self.obj)
File "pyooml.py", line 46, in init
obj.ViewObject.Proxy = self
AttributeError: 'NoneType' object has no attribute 'Proxy'

It should be fixed!
