Combiner Modifier
The Combiner modifier lets you combine multiple objects into single one. Apart from direct purpose, this modifier is useful when you should be pass several objects to another modifier, which may accept only limited number of objects. For example Extrude Modifier think of first object as path and second as path. To Extrude many objects, combiner may be used. Same with boolean.
