The basic tools (from the right hand buttons) doesn't support advanced features like trace. This is available when using drawing tools (:CC2DRAWTOOLS:)

1. Not following you here. Where did you find a cut polygon option?
2. Yes, creating your own tool will work fine. Just remember a tool will belong to the current style, the tool won't automatically be available in other map styles unless you manually load the tools from another style.

Celestial patterns are always good. Some moon/sun/stars stuff.

Dragons are also very nice for fantasy locations. Would fit perfectly in my campaign.

Which one you should have doesn't just depend on the number of add-ons/annuals, but which ones specifically. Not every style installs a file there, even if it would have made sense to have it, but it is a manual process making these in the first place, and I suspect they are often overlooked.

Here's the list of my files. I've got absolutely everything installed. You can check with my list and see if there is anything missing that you think you should have depending on your installed products. (The CSUAC, Bogie, Digital marked ones comes from the community symbol packs, and are not standard PF files.)

The program itself doesn't care about them, but Windows likes to have them available for uninstall/modify/repair action called from the control panel/settings. You might get errors uninstalling if they are not present.

That's a drawback whenever you deal with fantasy. In classic fantasy, one has to suspend disbelief a bit in the face of magic, which can do stuff not normally possible. In steampunk, one kind of have to accept the same of their steam technology. It's basically their "magic". I guess it is quite similar as to how utterly unbelievable our modern world would be to a renaissance person (It's just that our version turned out to be possible under the laws of physics)

It's not that lego got involved (AFAIK), it's just peoples tendency to build everything out of lego. Lego is a great outlet for creativity, you don't need the lego company to make a set for you to be able to make nice things. These days, you can even build lego online on their website, making designs without owning a single brick.

The article is found in annual 129 - Large exports.

Not sure about the line in the compass. almost look like a miter line, caused by sharp turns between two nodes, maybe some overflow happens with the calculation at that export resolution?

Note that the default symbol scale for metric maps is 0.3048 . That makes every symbol appropriately scaled, EXCEPT for the scale bar. When placing the scale bar, just right temporarily set the scale to 1.0 (but use the default value for all other symbols)

The easiest is to follow the instruction @Raiko provided above.

But for some more context. The Change background color command is a legacy command from back when backgrounds were solid colors, before we started using bitmap fills. When an entity has a bitmap fill, the color won't be visible (because you see the fill instead), so this command will appear to do nothing. As such, just ignore it unless you work with a map with a solid color background.

As for the error message about "FREEZE BACKGROUND", the cause for this is that the macro behind the command attempts to freeze the background layer, so this is a command, not the name of a layer it looks for. However, if something goes wrong with the macro (like it can't find a background entity [not all maps have one]), that can lead the macro to interpret that line as input to the layer selection instead, thereby complaining it can't find a layer with that name.
