[Qgis-user] cut several segments into a polygon

[Jake Maier]

Thank you Randy,
I did have some trouble with the difference plugin in so far as it seems not
to cut holes into the layer, but instead give me the individual parts. I'm
not sure what I may have done wrong.

Hi Jake,

I had a plugin in preparation that amongst others does exactly what you
want: within an editing session cut out from polygons in editable theme with
selected polygons from another theme.
The plugin is called DigitizingTools and is planned to contain more tools in
the future. I uploaded it to the plugin repository just now, feel free to
give it a try and report any problems.
It is marked as experimental (because it is not well tested right now) and
only works with current master (aka QGIS 2).
