Im trying to get my head around this: I want to work out how to come up with a number that I can use to make larger measurements a smaller scale version? So if a person is 1800mm tall and i want to make a smaller version which is 85mm tall? Then with the scale number I can use it on different objects and make them the same scale? For example something that's 1000mm tall I can scale it so it's the same scale as the original query? Does that make sense? How do I work it out?
