Hi guys once again ! I'm having a problem in snaping!! I'm used to modeling in AutoCad and i can snap everything i want to help me obtain the most perfect effect! In Maya i'm having some problem with it and its slowing my work ! In the picture below i show you 2 specific situations:
1 - snaping the that corner of the surface to the polygon is easy but how can i make the inverse? Snap the surface point to the edge?

2- I need to split that surface at that point and -90º direction, how can i do it?

Sorry guys im used to do everything perfect in AutoCad and taking the first steps in Maya!!

Thx alot in advance
