[Qgis-user] draw polygon

[Richard McDonnell]

Hi Salvatore,
You could try:

1.       Selecting/Highlighting Polygon 1, which should also highlight the area you want to cut into area 4.

2.       Using the Split Features tool, you can then create a cutline to clip it successfully, something like what’s shown below in green, should work.

The polygons 2 and 3 shouldn’t be altered, as the Split feature tool will only alter the Selected/Highlighted Polygon 1

Hope that helps.
Regards,

Richard

I tried with the split features toll but I received an error. Any solution?

Thank you.
