[Qgis-user] complete a polygon

[Blumentrath, Stefan]

Avoid Intersection is under “Settings” --> “Snapping options”.
If that is checked for your layer you can simply continue digitizing with the “create polygon” tool…
Cheers

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.

If I have understood your question correctly, you can use AutoTrace plugin.

Hi,

I have to add a new polygon to other existing; they have obviously

common sides; how can I draw only sides not common?

Thank you
