Hello! 1. Is it possible to calculate length of every edge of polygon? 2. And add results to layer near each side of polygon? I calculating length of sides now by GeometryService.distance(params); In distance() I send two points on opposite sides of the edge of polygon. It works very well but I have problems with adding label with length to correct side of polygon. I just thought that exists function that makes it all (placing sizes of polygon on map in the right place).
