3D Studio Max : Best way to snap

I'm a newbie to 3ds, but have used other graphics tools, more on the engineering side of the house in the distant past.  Anyhow here is my question, how do I snap a point on one object to a point on another?  For example, I create a square and a cone.  I want to snap the tip of the cone to the center of the top of the square?  I remember doing stuff like this all the time in my previous tool, i.e. create a local coord system in the middle of the two corner vertexes.  Then snap the cone to that local coord system.  I have tried playing with the snapping tool 3, but that doesn't seem to work to well, or more likely I am unclear on the concept.  Can some one give me step by step instruction on how to do this?  I know I can manually translate/rotate the cone but this is tedious and probably unnecessary.  

Thanks,

Micah
