I'm trying to use the tool "delete ring" in order to create a hole in a polygon. The geometry of the hole is another feature of the same shapefile

I cannot manage to delete the part of the polygone. Does someone have a tutorial or some explanation?

I would like to "Add Rings" but using other polygons. Example: I would like to delete the two selected polygons and create holes under them in the big polygon where they are. Is that possible? Thanks! – Egidi Sep 25 '12 at 12:41
@Aitor You seem to still be active on GIS SE, whereas Lucien has not been seen here for 18 months. If you or anyone else wants to try and get an Accept-able Answer (the current one seems to overlook the requirement that an existing feature should be used to create the hole rather than digitizing) then I recommend that you edit this Question to bring it back onto the active list. – PolyGeo Jan 9 '14 at 1:23
Is there a way to add rings based on existing polygon feature classes? Or does one have to draw the new geometry? – Dan Wolf Jan 30 '15 at 19:14

You should be using "Add Ring" tool to create a hole in the polygon.

Just Select the "Add Ring" tool and digitize a hole inside the polygon. It will remove that part and create a hole.

for qgis 2.10 to enable the toolbar go : Edit -> Toolbar -> Check Adv. Digitizing. – nickves Jul 20 '15 at 12:36
