1 | 1 | Normally, when you get/set the position of an object, you actually get/set the position of the object's *center of mass*. In many cases this is enough, but when the object's center of mass *isn't exactly its geometrical position*, and you want to locate it (or locate something in it) geometrically, just "getting its position" won't cut it. |

5 | 5 | The trick to solve this is to take the vector reported by [[Get Position]] and **offset it by half the total size of of the object**. With total size, I refer to the minimum and maximum vectors of the object, added together. |

9 | Almost similarly, to set the geometrical position of the object, you set the position of the object to where you want to place it offset by half the total size, **negated**. Or, equally, subtract the offset from the geometrical position. |
