[Qgis-user] complete a polygon

[SIT delle Riserve Naturali di Legambiente Sicilia]

Dear Saber, thank you!
But this tools allows me to complete a polygon "inside" another.
I'm searching for a tool that alow me to complete a polygon outside 
another, that has common sides
If I have polygon 1 and 2, andI wan to to digitize polygon 3, I'm 
searching a tool that allow me to digitize pol 3 without redraw the 
common sides with 1 and 2 (in thi case ise very simple redraw,, but with 
complex and natural polygons it is an heavy WORK!!)
Thank you.

Tata
