[Qgis-user] Polygons inside a polygon

[Hakala Oiva (MTT)]

Hi everyone

I just cannot understand, if Qgis cannot handle this:

I have a multipolygon layer and a bigger polygon with 3 smaller polygons inside it. I want to modify the big polygon so, that there should be 3 holes just where the smaller polygons are. So actually I want: big polygon - 3 small = result polygon (with 3 holes). I know how to use ring tools, but this is not the same. And notice, that I do not have 2 layers, just one.

Thanks, Oiva
