Moving on another object

Scripting
1

I need a button that moves selected objects over another object (“ground”):
1-select the "gound"
2-select the objects I want to move on it
3-move the selected objects on the upper side of the ground (like gravity)

Is there a button (with some macros or script) that can do it?

thanks in advanced

Hi and thanks a lot for your link.
Yes, I’m looking for something like that but more simple.
Take a look at this plugin for 3dsmax:
