to To do this need to extend a The first step is to For this we need the following lines of code:fmModel.CoordinateSystemmf.CreateCoordinateSystem()In the first line we declare the MapFunctions library as the variable "mf". The next line sets the coordinate system of our model to WGS 84 / Pseudo-Mercator. To create the coordinate system we use the EPSG code (3857).
