Apache Tut 5 extrude face snapping problem
 

I asked this in the newbie forum, but no one replied and I really, really need some help.

I'm at about the 33 min mark on the Apache tutorial, module 5, and I've encountered some weirdness when I try to extrude. Up until now, aside from some weirdness with manipulator direction, the extrude face has been working like a charm. However, as I was trying to extrude faces on the front of the Apache, all of a sudden the lower left corner started to "snap" to an area behind the smoothed mesh. The other weird thing is, once it snaps, you can't undo it. Maya says there's nothing to undo. Another thing is that I tried extruding faces on other parts of the model and it works fine. The only place it does the weird snapping is on the piece you made using curves to extrude polys to make the front half, and it doesn't matter which face you try to extrude. If it's a face on that curved piece, the weird snapping occurs. I'm tempted to delete that part of the model and just start over.

I've attached a pic that has a before and after pic, as well as my tool settings and my extrude face tool settings. I cannot understand what is going on!

The settings are the same has they have been all along and I cannot figure out why it is acting this way. I know it must be something simple, but I don't know what it is. Please help!!!!

Thanks.

The only thing I can suggest is that you might have switched on Snap to grid or snap to curve by mistake??
