I would need to create a polygon from the points. Transformers I've tried:
- PointConnector: How can I sort the points using only x and y?
- HullAccumulator: I can't find an alpha value, which would work for this. I've tried 0.2-8. If alpha is small, I don't get the whole area geometry. If alpha is big, the area is too generalized.
- SurfaceModeller: Problem is that, the surface boundary forms a convex hull.
how about first using the HullAccumulator to create a generalized polygon, then using the AnchoredSnapper with the input points as anchor to snap the polygon boundary to the original points.
You might need to use the Densifier with something like a 0.5m distance to create vertices on the polygons first. If so, you could use a Generalizer later to simplify the polygon again.

You can try the following approach:

The overshooots pose a challenge tho..
i do that often to like order labels for easy reading/finding

Itay: Thanks! With your suggestion, I got closest to the result. You're right, the usability of the result depends on the accuracy and usage of the end product.
Gio: Thank you for the clever suggestion! I didn't quite get it working. If I use azimuth to the centrepoint as the order, when the wall goes inside the building, the order is messed up: http://www.imgy.eu/i/88s90y9213uo.png.
