question

Hello @Miguel_ngel Ra sure, I'll send you the code and explain what I have done in it.

//create a navigator object
Object navigator = model().find("GISNavigator");

//clear all the previous points in the map
navigator.subnodes.clear();

//reference an existing global table with all the cities and their latitude and longitude 
Table table = reftable("GlobalTable1");

//a for to search all the rows in the global table
for(int i = 1; i <= table.numRows; i++){
        //create a point in the navigator
        Object point1 = createinstance(library().find("/GIS/Point"), navigator);
        
        //set the properties of the points using values from global table
        point1.name = table[i][1];
        point1.setProperty("Latitude", table[i][2]);
        point1.setProperty("Longitude", table[i][3]);
               
        //set the size of the points and their color, nothing really important
        point1.setSize(40, 30, 20);
        point1.color = Color.red;
        
        //store all the points in a vector in case I need them, not really important too
        vetor_pontos[i] = point1;

        //repaint the map to show new points
        repaintall();

In my model I did not connect all the dots when creating them, I am using clusters so when creating teh cluster, I also create the connection

contextdragconnection(point1, point2, "A");

And after the connection is done, you can use the following code to get their distances

double distance = function_s(point1, "getDistance", point2);

It is also worth mention that to fill my global table I created a function that gets all the data from an Excel spreadsheet and only them I referenced it as showed in the first piece of code.

If you have any other question that I can help, feel free to send me another message and sorry for taking a lilttle long to answer you.
