Is there a way to orient an object based off of another surface?
For instance, i have an object that i want to orient one face, with that of another on a different object so that it lines up. Is there some function that allows me to select a face from each object and then have one object orient and move to the other face?
I have PLEs 6 AND 7, so if there's something in either, that'll be great.

Also...is there a way to smooth just a particular part of the model? rather than the whole object, just the selected faces? I find it a real pain to have to add a bunch of edges just to keep the shape of something on the object when i convert to subd or smooth when i only need some blocky-looking areas smoothed.
