question

I'm not sure from your post if you want just to make the connections from a line definition that is stored in the global table, or if you want to alter the layout too.

This will do the connections.

contextdragconnecion(<fromobj>,<toobj>,"A");

If you want to align them just create a loop and set each object's x location to that of the predecessor plus that object's x size plus a margin.

Object posobj=Model.find("Source1");
double y=posobj.location.y;  //align in y
double margin=0.2;
double x=posobj.size.x+posobj.location.x+margin;
while (posobj.outObjects.length>0){
    posobj=posobj.outObjects[1];
    posobj.location.x=x;
    posobj.location.y=y;
    x+=posobj.size.x+margin;
}
