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

Hello,

I need to draw a polygon, the blue one indicated in the figure below:

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

Thank you.
