I'm trying to Drag Components, but when I click on the object I want to drag, it makes me control like 5 or 6 other objects. I just want to control one object.
Are they mated? If so, and they have degrees of freedom, they will come with the component you are dragging. Alternatively, you can use "Move Part" or "Move Multiple Parts", just be sure to set the options about whether to maintain relationships.
