Smart Object Arranger
Does Smart Object Arranger work with objects of different sizes?
Yes. The add-on uses the real world-space bounding boxes of selected objects, so Grid, Row, Column and Pack layouts take different object dimensions into account.
Why does Restore Original return objects to a different position than expected?
Restore Original returns objects to the state saved before their first arrangement, or to the latest state saved with Set Current. Use Set Current whenever you want the current arrangement to become the new baseline.
Does Smart Object Arranger modify or delete my objects?
No. Smart Object Arranger only changes object transforms such as position and rotation. It does not modify mesh geometry or delete objects. You can use Restore Original to return selected objects to their saved starting transforms.
