Scaling?

[Dagotte]

Ok, So I just got started and have a few successful prints done, but so far all of them have been a single piece (a bust or a figure that has been scaled to the size of my build plate). I'd like to try something different now and selected a more complex piece that has several parts. How do I ensure that all the separate parts will fit correctly when printed separately? Is it as simple as setting them all to the same reduced size (say 100% to 75% to fit on the plate) or am I missing something?

Thanks for any /all responses & assistance!
