I've got UNION ready, but haven't gotten to DIFFERENCE yet.

Yes, with presets, you must apply them manually to each map. But the advantage it that it can be done with existing maps, and not just with apply to new maps.

Looks to me like the easiest way to have it working is to not use white as the base color of your polygons, but some other color. The color will be ignored anyway with your current RGB Matrix setup, and by not being white, you don't run intot he problem Joe describes of being ignored because it is the same color as the background.

The wizard fetches things from the map template. So you should be able to fix this by editing the template file for that style, which should be found in @Templates\Overland Maps\Wizard

I assume you are talking about the Annual Jon Roberts cities here?

I think it is just a color issue, the symbols in this style is quite simple, and mostly white, and the white symbols on the white background makes them invisible.

Note that you don't have to place them from the new map wizard, you can also access these symbols after starting the map by hitting the :ICON_DRAWING: button. (They'll be just as hard to see in the symbol catalog window though, unless you change the view window color from the View menu to something not white.)

Maps are now in the atlas. Thanks Quenten.

Very nice. Any reason for picking that location?
