Cut a geometry along a polyline.
Use case
You might cut a polygon representing a large parcel to subdivide it into smaller parcels.
How to use the sample
Click the "Cut" button to cut the polygon with the polyline and see the resulting parts (shaded in different colors).
How it works
- Pass the polyline to the static extension method
GeometryEngine.Cut() to cut the geometry along the polyline.
- Loop through the returned list of part geometries. Some of these geometries may be multi-part.
