Start from here.

Well, let's start to try.

The image of use is,
1. Run this code - add 'Cube' at center automatically
2. Push 'Generate' button
3. Generate eight objects around the center cube
4. Select one from them
5. Do step (2.)

inside the code

1. Add one cube at center (0, 0, 0)
2. Set eight operations as function
3. Duplicate 'Cube', and do each operation
4. Select one object from new eight objects
5. If push 'Generate' button, delete unselected objects
6. Set the pos of selected object to center(0, 0, 0)
7. Set the name of this object to 'Cube'
8. Do step (3.) again

There are two problems now.
1. How to set the pos of selected object to center
The line 64,

<CODE>
bpy.ops.transform.translate(value=(0, 0, 0), constraint_axis=(False, False, False), constraint_orientation='GLOBAL', mirror=False, proportional='DISABLED', proportional_edit_falloff='SMOOTH', proportional_size=1, snap=False, snap_target='CLOSEST', snap_point=(0, 0, 0), snap_align=False, snap_normal=(0, 0, 0), texture_space=False, release_confirm=False)
</CODE>

is, translate the object relatively. So this value=(0, 0, 0) means [no move].
I need to set the pos absolutely (0, 0, 0).

2. How to set the name of the selected object arbitrary.
I have to select the object named 'Cube', but duplicated next generation object has 'Cube.00x'.

How about it?
The all code is here.
