Constraints at their most basic are controllers, controlling how one item relates to another. Constraints can serve many purposes, and when used in combination with each other can create very complex controllers and motions. MODO's constraints are weighted, meaning that a weight value can determine the influence a constrain has over the item it's controlling.
