I think the problem is again the part itself. To line up parts you need to
have reference points where you can line up. LDraw parts do not have such
points.
The same thing is valid for intersecting parts. I'm sure it's possible to
detect that parts are intersecting, but how to you move the part that it
doesn't intersect and that it is lined up correctly. Also I believe that
such a process with a high number of parts can easily end up in a mess of
calculation-power imagine a part in the center of hundreds of other parts -
when the center-part is wrong and you have to move all the other parts into
different positions ....
