Batch Polygon Groups to Object Script
This script will do the same as Polygon Groups to Object command but in batch mode. Select polygon objects and run script. All your objects will be disconnected without preserving polygon groups and placed under an empty null.

Make Editable Command as Python Script
You may use these syntax to insert objects to the object manager:
- BaseDocument.InsertObject ()
- GeListNode.InsertUnder ()
- GeListNode.InsertAfter ()
- GeListNode.InsertBefore ()
There are same.
