Everyone have the CC3, DD3 and CD3 buttons, as both dungeon and city tools are included in the CC3+ base these days (Only the tools, you need the products to have the artwork, but the tools are very useful with artwork from other products, like SS4/5 or the annuals)

The WW2 button should be added as long as you have the WWII.mnu file in your data directory (which should be put there by the installer).

Looks very nice, but since you have gone for a more "expanded" settlement view, instead of a single symbol, maybe that dashed line for the road isn't the best, as it crashes a bit with the rest of the visual. Those dashed lines work best when you keep everything on an "abstract" level (Such as using a single symbol to represent a town).

All tutorial maps from the user manual should be in @Tutorials\UserManual. If any are missing, I'd very much like to know which. And yes, they are installed along with CC3+.

And yes, this is a good place to seek wisdom. :)

CC3+ doesn't have a way of changing the colors of the UI.

However, you can change the map background color from white to black (View -> View-Window Color, and set it to color 0), this will get rid of a lot of the white. Not sure if that is enough for your use case or not, since the rest of the UI will still be the standard light grey. (Note that this setting is a per-map setting, so you can't set it globally, and once you set the background black, you'll probably immediately notice the white screen that is around most maps, which then also can be changed to black via :CC2MCHANGE: on the entity)

Kangaroos in the Snow?

For you southerners, I do remind you that I wrote winter or holiday themed, so a typical Aussie Christmas scene is fine, it don't need to be wintery if it looks Christmassy.

None of the basic tools from the right toolbars can trace. That is an advanced feature only available on the various draw tools (hit :CC2DRAWTOOLS: to list the tools for the current style).

If you need something not there, you can always make your own tool by duplicating an existing one and setting the shape (and other properties) to what you need.

You can easily import one or more scanned map into CC3+.

Do note that it will only be a flat background element, it won't be converted to actual CC3+ symbols and entities, and won't be modifiable inside CC3+, as CC3+ isn't an image editor. What most people do is to import a scanned map and keep it as a background image to trace over inside CC3+, to basically recreate the map in CC3+, using the scanned map as a guide.

You can also keep the scanned map as a background element and place things on top of it, but that might look a bit weird, depending on the map, since the style of the background probably won't match the style of the CC3+ symbols.

Which symbols are you trying to place? Almost all of the Traveller symbols are designed to be offset to the placement point (center of the hex) on purpose, because they are supposed to be placed according to the official guidelines. Only the main world itself will be centered, the other symbols are intended to "surround" it at fixed offset/position depending on symbol type.

As for scale, the Traveller symbols are scaled to fit a grid size of 1. If you make your hex grid larger than that, you also need to change the symbol scale accordingly.

The offset is because in Traveller, the base is supposed to be in the same Hex as the planet, in the 10 o'clock position. With the offset in place, you just click the planet down in the middle of the hex, then followed by the base in the same position, and thanks to the offset, it will be perfectly placed every time.

The reason you get it in a different hex is that you have the symbols scaled too large. I realize that this is how you probably want them, but in Traveller, the planets only occupy a small part of the hex, with room for symbols and names surrounding it in the same hex.

If you are not making a traveller map, I recommend using a different symbol catalog. You'll find the same symbol sin other Cosmographer catalogs without the offset, with the exception of those very simple Traveller-spesific symbols (Such as the bases)

That can be an advantage, but remember it is valid for the entire session, so it will affect future maps opened in the same CC3+ session. Not likely to negatively affect most maps though, but worth being aware of if something weird happens.
