When using a donut as a Clipper the Clippees on Clipper Boundary setting does not work like described in the documentation. It says:
This parameter directs what action should be taken with Clippee features that lie entirely on the boundary of the clipper.
Treat as Inside: These features that lie on the boundary are output via the Inside port. Treat as Outside: These features that lie on the boundary are output via the Outside port. Treat as Inside and Outside: Points and line segments on the boundary are duplicated and output as both Inside and Outside.So the data I have is like this:
The donut is the clipper, the blue lines lie entirely on the boundary of the clipper.
The parameters I use are like this:
Single Clipper, Clippees on Clipper Boundary: Treat as Outside.
The result is like this:
The green line, on the outside of the area, leaves the Clipper correctly from the Outside port. The red line comes out of the Inside port. I think this is not correct.
Found this in 2017.1.2.0 (build 17722) and was able to reproduce in 2018.0.0.1 (build 18295). Workspaces attached.
Workaround is to use a DonutHoleExtractor and two Clippers.
