Hi Markus and thanks for your answer.

Before moving to my data, I am doing some tests with 2 vector layers:

Basically the small one, should snap to the bigger one.
The command line I use is this:

v.edit map=origine bgmap=destinazione cat=1-999 tool=snap thresh=-1

But nothing change.

In the log I have got a lot of line like this, both if i set thresh -1 
or 500
[..]
D1/1: Vect_set_thresh(): thresh = 0.000000
[..]

Thanks for your help

Luca
