Hi,

This command will center your object at the origin point :

I often combine it with "Put on Ground" :

@ Michael,
By the way, is there a possibility in MoI to run two scripts in sequence. For example A shortcut that would execute the script "CenterAtOrigin" first and then "PutOnGround" ?
Thanks
