The wayfinding use case usually implies lots of hallways and intersections where people need help to find their destination.
Wayfinding paths are the equivalent of Google Maps and Roads. They should be added by someone who has knowledge of the space and goal.
A good example is a hospital where you would want paths in pubic spaces, but not anywhere protected by a card reader. It is a good idea to create a paper map first to clarify any areas that are out of bounds.
The blue dot (what people would see) will have a strong affinity to a path, but if the location estimate gets 4 meters or so off the path it will detach and go into x,y mode. In some use cases that is OK, but keep this point in mind when you are designing for your use case.
This is a quick video showing how you add way-finding paths.
We strongly advise that you zoom the map and take a closer look at the lines. The lines might look like they connect when the map is scaled out, but closer analysis might show that they actually do not connect. This will cause problems so please keep a lookout for this.
