# Blender.Object module and the Object PyType object
"""
The Blender.Object submodule
B{New}: L{Object.getData} now accepts an optional bool keyword argument to
define if the user wants the data object or just its name.
Object
======
This module provides access to the B{Objects} in Blender.
Example::
import Blender
scene = Blender.Scene.getCurrent () # get the current scene
ob = Blender.Object.New ('Camera') # make camera object
cam = Blender.Camera.New ('ortho') # make ortho camera data object
ob.link (cam) # link camera data with the object
scene.link (ob) # link the object into the scene
ob.setLocation (0.0, -5.0, 1.0) # position the object in the scene
Blender.Redraw() # redraw the scene to show the updates.
