I'm not going to post a tutorial, but the short answer is that it turns the
referenced sub-model inside-out. So, for example, the cylinder primitive by
default has its walls facing outward (like on a stud). If you put INVERTNEXT
before a cylinder primitive, you'll get one with walls facing inward (like the
inner lining of the hole in a technic beam.
In general, I really think you should only use it to invert primitives. So if
you use a primitive in your part, and see that the BFC is wrong, INVERTNEXT
should invert it to be correct.
