[Qgis-user] cut several segments into a polygon

[Randal Hale]

Hey Jake,

Here's how I typically add a cut to an existing stand (or depending on who
you stand in front of - regeneration cut or clear cut).

1. Select all of your clearcuts in the stand.
2. IN the QGIS menu go to Vector -> geoprocessing -> difference
3. Both the input and the difference layer will be the name of your
shapefile with the stand in it.
4. Uncheck "Use only selected features" under Input Vector Layer
5. Make sure "Use only selected features" is checked under difference layer
6. Create an output shapefile and run.

You should have a new stand with multiple "holes" cut into it so you get
the right acreage.
