Snapping distance

Hi, all!

In Blender 2.7, how can I adjust the snapping distance ( the minimum distance at which the active element - vertex, object, whatever - will actually and automatically snap to the target ) ?

Thanks in advance,


P.S : this should work in 3D, if possible.

There isn’t actually a minimum distance at all, the object just snaps to whatever your mouse cursor is over. Unless you are referring to the pixel distance used to determine what your mouse cursor is actually over.

That’s it. How can I set this distance ?
