Hi Burr, yup when you do a boolean the styles of the original objects are preserved.

That's so you can do things like construct a knob, assign it the style you want to render with at the end, then replicate the knob, then do a boolean with a larger base object and through all those steps the styles are preserved.

So because of that you can have a chance to set your style early on and have it replicate through various modeling steps so that you don't have to do it all at the end by picking possibly a whole bunch of little fragments, although you can still do it that way if you want.

I am going to try and put in an option so that you can turn that off if you want though, since some people are used to working in other systems that do not allow having different styles on child objects.
