After saving, we can play some more with the model, and save another version of the map and its template if we like. I select the 'hull' group from the Select menu. The selection rectangle selects the ships hull. Note the red superstructure is not part of the selection. I think I will use Box mapping on the hull.
Some parts overlap the red superstructure.
Oops, I will clean that up before saving. Perhaps I will decrement the selection size. There are lots of options. Play around and try them out. Below are the keystrokes for manipulating the selection in the map window.
