I think you mean map units, not scale. All city maps are the same scale - which happens to be the same scale as a dungeon map - 1 foot to one map unit.

As to the correct size, you will probably be a week or so discussing that one with everyone else, because the size of a city is only party dictated by the size of the population. If space is cramped cities are also cramped and tend to have more taller buildings than a city with the same population built in the middle of a vast plain. There are also cultural issues to consider. What is the accepted maximum number of families per household. In the UK just a couple of hundred years ago at the dawn of the Industrial age it was quite normal for 2-3 entire families to live in a single room of a multi-level building where they had come in from the country to find work in the new factories. These days people would gasp in horror at the very idea of it. We live very insular lives, and there are many who live as single adults with a whole flat to themselves.

There are many other considerations, but you get the idea. It's very much up to you how big you make the city, but useful to count each building by how many people you would expect to be living in it.

Ralf did a Live Mapping session on this just last week here:

@CredePendrel - The settings should have been installed by the annual installer. I helped you with this on FB, but for the record here is the solution if the settings files do not appear.

Check if they are listed in this folder first:

@Program Files (x86)\ProFantasy\FT3\Export

If they aren't there, go to this folder and copy them across:

@ProgramData\Profantasy\CC3Plus\Annual\Issue 155 - The One Day Worldbuilder\FT3 Export Settings

Then if you have FT3 open at present save your work and re-open it. The settings should now appear.

...

I am not sure why they didn't get installed with the annual. It could be any number of things, like forgetting to install as the administrator. That one comes to mind first because the destination folder is a system folder, and requires admin permission before you can save anything in it.

It looks like you've got a good result despite early troubles :)

The pasting in CC3 does take time, but that is because you probably have quite close to the maximum number of nodes for a CC3 map just wafting around on your crosshair. The great thing is that CC3 is nowhere near as crashy as some other software I don't care to mention (but which lost me several day's work just recently by both crashing AND corrupting the file for good measure), it just takes rather a long time to refresh.

You can place the map by typing the origin coordinates on your keyboard and hitting enter once it is ready to be pasted - as you probably did, but then it takes a while for the refreshing to finish and the paste to complete. Patience is all that is required, though :)

In addition to the advice I gave before about creating your own subfolder in Documents (7 September), I also find that it is really handy to save that folder in the Windows 'Quick Access' panel, so that it's only ever one click away.
