Absolutely. Without a scale I have no idea about the size of the world. Is the circumference 1000km? 25000km? 100000km? A scale provides very usefull information to any map, even if it isn't accurate for the entire map.

As mentioned in the mapping guides for those two issues, it uses free resources from the CSUAC collection, in addition to standard ProFantasy Resources. Se the mapping guides and this post for more info.

That priority is the Sheets. The order of the sheets in the dialog is the drawing order, so if something is on a sheet further down the list, it will drawn after, and therefore on top of, things higher in the list.

You can always move things like the swamp to another sheet using :CC2MCHANGE: after you have draw it if it isn't on the sheet you want it to be. The drawing tool places it on it's default sheet automatically, but you can move these entities around as you want.

By stickers, I assume you mean symbols? You can always change the scale of a symbol before placing it by right clicking inside the map (with the symbol at the cursor) to get the symbol properties dialog, or you can hold down control and move the mouse up down to change the scale visually. You can also set the default scale from the :CC2PRESETS: dialog, this is the scale it will use when loading the map, or hitting set defaults in the symbol properties dialog.

The fact that you are wanting to reduce the size of this leads me to believe that you might be attempting to draw a bit too detailed map. You should always be carefull how detailed you make a map, for several reason. Reason 1 is simply performance. Every entity you add to the map is another thing CC3+ needs to keep track of and draw. CC3+ isn't like a bitmap editor where you just change the color of the pixels, but the performance is the same with a blank image as with a pattern-filled one. Trying to add to much detail also makes the map look very cluttered and unreadable when you try to zoom out to look at the overview of the map. The second reason is mapping fatigue. Trying to map out a large map in very tiny detail is extremely time-consuming, and most people who have attempted that burtn out long before they get clode to finish. I allways recommend keeping the detail level at a reasonable level, and instead make additional higher-detail regional maps of the more interesting regions, rather than tackle everything at once. Kind of like we are doing it in the community atlas.

Sounds like your map size is perfect. If you want it to be 6000 by 3800 km, then 6000x3800 is the correct values for the dialog when you started the map. You'll always want the number of map units to match the actual real-world size of the map. If you used those numbers, you shouldn't resize anything, since it is already correctly scaled.

If you don't like the scaling of the fills, change the fills. You can do that from the fill style dialog, just click the fill style indicator in the top right, go to the bitmap files tab. select the appropriate fill, and change the value for scaled.

If you need to change the sheet an entity is on, just use :CC2MCHANGE: on the entitie and put it on the correct sheet.
