Do you have the CA66 Isometric Dungeons issue? There is a furniture symbol catalog in that one (@Symbols\Dungeons\Annual Isometric Dungeons\CA66 Furniture.FSC) that has a proper 4-way throne that should fit.

I think there are some limits concerning what those value will actually change. I am pretty sure they only change the fractal function, i.e. the randomly generated world, and does not affect imported real world data or manual editing. From your description of working with Earth and Hudson Bay, I assume that may be the issue for you.

Not that it will help you do what you are trying to do, but I am pretty sure if you generate a new synthetic world and then change those values, the world should reorient.

I don't use that function very often though, maybe @jslayton have anything to add or correct.

Some general organizational rules to avoid red X'es in the future.

• Make sure to never edit, move or rename any art file (fill or symbol) in the CC3+ data directory, never attempt to reorganize them.
• If you want to bring your own art files, either brand new ones edited copies of official resources, make sure to have a custom directory structures for them INSIDE the CC3+ data directory (Remember, you can make your own subdirectories inside the existing Symbols and Bitmaps directories), and once the art files are in there, remember to treat them according to the rule above.
• When importing fills into a map, always make sure they are imported using correct relative paths, so that the path starts with @Bitmaps for fills and @Symbols for symbols and not something like c:\programdata or similar. But as long as you followed the rule above, both the import symbols and import bitmap dialogs's "realative to CC3 path" will work and do this automatically, and as long as you follow this for every map, then fills imported using the insert file option Sue mentions will also be correct.
• Never try to import a fill or symbol not in the CC3+ data directory. Stick with the above rules, starts by putting it in the data directory, THEN add it to your map from there.
• And as long as you followed the above, getting it up and running on a new computer is also dead simple, just install all the same add-ons, and then copy over your custom artwork directories to the same relative location as it came from, and you are set.

All the main add-ons have their own menus. I don't think there is a central location where this is stated, but the toolbar for each add-on are discussed as the first thing in every add-on's chapter in the Tome.

For the city legend, I am assuming you talk about the index (Create Index in the City menu), you can find it on page 398 of the current version of the tome. Unfortunately, search is rather dependent on using the right words. Which of course, is difficult to know when you're searching for something you are unfamiliar with. Acrobat is not smart enough to search for similar terms, and making a list of all the words people may use when searching for every single term used in the book is also rather unfeasible. Maybe in the future it will be possible to use an AI to search the book that actually understands the context, which would make it easier to use alternate terms and still find what you are looking for.

This is an unfortunate bug with some of the vector symbols when you have CC3+ running on the Arm platform. CC3+ is a using the x86 instruction set, so when running on the arm cpu, there is a compatibility layer that translates the instructions from x86 to arm, but unfortunately, something goes wrong.

It is the same issue as you experienced here: https://forum.profantasy.com/discussion/13970/pete-fenlon-revisited-symbols

Unfortunately, there isn't anything we can do about it right now. I recommend staying with styles that use raster (png) symbols for now.
