Geometry Engine Cut generates wrong results

BITDeveloperNickSwartz — Mon, 14 Feb 2022 16:46:32 GMT

I am trying to cut a highway according to the extent of the screen. The following screenshot is a visualization of the cut boundary (vertical dark green line), and the resultant geometry after the "cut" operation

As you can see it creates an array of three geometries (index 0 is the black line, which according to the documentation should be to the left of the vertical line. The light green line somehow spans either side of the cut line. Then there is a section that touches the cut line. Not sure what's going on here. I might try to tackle this issue a different way.

Can you share a code pen with just the geometries involved in this image? That way I can take a closer look at what might be going on.

Unfortunately I don't think that's an option. I could try to develop some pared down snippet, but this comes from a very large/complicated app that works on secured services. Thanks

Solved this issue by creating polygons using the extent of the screen and the extent of the polyline feature i was trying to cut. That way I was able to use the more reliable "clip" tool in the geometry Engine.
