Split Polygon feature layer by the Polyline featur layer

[TerkaHolubcova]

Hello,

I would like to ask for your help. I have a polygon layer representing building blocks and a polyline layer representing borders.

I’m trying to find a way to split the polygon layer using the polyline layer. I only found the Split Features tool in editing mode, but it doesn’t seem to work for the entire layer.

It doesn’t look like it should be that complicated, so I assume I might be missing something.

Thank you,

Terka

Hey @TerkaHolubcova 

I think you may have luck using the Feature To Polygon tool, as it contains polygons for areas enclosed by input lines, so everything inside of those lines would split!

Another workflow I found that worked in my testing environment:

1.  In the Modify Features pane, select the Split tool.
2.  Click the By Feature tab.
3.  For Input Features, first set your line layer as the only selectable layer in the Contents Pane.
4.  Select all your lines in the lines layer.
5.  Click the Target Features tab.
6.  In the Contents Pane, unselect the line layer and select the polygon layer as the only selectable layer.
7.  Select all your polygons.
8.  Click the Split button lower right of the Split tool.
9.  Unselect all selected features.
10.  Turn off the visibility of your line layer and voila!  All polygons split by lines.

Good luck!
