What's up Simply Maya Community,

I'm back with another total newb inquiry! After viewing Digital Tutors lessons I'm a bit perplexed by some basic techniques they neglect in the tutorials so I turn to you.

1) Is there a way to grow a face/edge loop selection one face/edge at a time? (Shift+Period or Up Arrow give larger selections and entire loops)

2) How can I select a face or surface and have another object snap to that plane no matter the angle?

3) How can I prevent marquee selection from selecting faces/edges through the entire object?

4) What is the fundamental difference between using reflection and duplicate special to mirror actions while modeling?

Thanks for all the great support!

Cheers,
Eric
