You find that command by right clicking :CC2EXPLODE:

Just one addition to Sue's explanation above.

From the small screen shot, it looks to me that this may be an FT export? If so, it may be a multipoly (depending on your export options). If it is a multipoly, it needs to be exploded |CC2EXPLODE| first.

(Note that exploding it will also means that any "holes" [lakes] in the landmass will disappear since they will be turned into their own polys instead of defining holes in the multipoly)

Wyvern's new holiday location is now alive in the atlas. Thanks for contributing these interesting maps.

Technically, you can just chuck any template into @Templates\Cities\Floorplans to use that style. Note that it does look for certain tools to set the fill/sheet/other properties of the walls/floors it draws as part of the floorplan (The Wall, Default and Floor, Default tools), so if those tools aren't present, they will just use a solid fill instead, but the shape will be drawn, so you can just use change properties

Great. This is a valuable resource, so good to see it back.
