Align pivots in Maya

This script allows you to copy object pivot translation and rotation from one object to another one. How to use:
- copy code to the script editor "Python tab"
- select source object
- select target object
- execute script
Works on multiple selection. Align all object pivots with last selected.

2. Add to selection target object
3. Run script by 'import copyPivot\n copyPivot.copyPivot()
