This tool will spread out a group of objects to check them/view a library.
To get the best use out of this all the objects need to have their pivots centred and be 0,0,0 at the origin.
The space multiplier allows for greater gaps between objects depending on scene scale.
In an updated version this would have an option to use each objects bounding box.

The number of rows in X can be increased or decreased and everything can be re-centred back to 0,0,0 when finished.
