I am making my own maps from scratch.. making the walls in a very square ordinary fashion.. then I make the keep in a very square and ordinary fashion.. then I make guard towers.. I make then holding Alt and making them circular I don't make then really small just about 1/4 of a square.. I then copy that and paste where I need to.. but I get them close or they tend to over lap the walls so I copy them close to the wall and then move them.. If I do that 5 or 6 times.. the rest of them that I make I can't move.. I can turn and manipulate them.. but I can't move them to the right spot.. and trying to copy it in the exact spot I want is very difficult and time consuming.
