I recommend the last of Monsen's suggestions. ie draw normally, then rotate. I had the same issue a while back.

I have the same experience as Sue, and the same solution.

Can we get a catalogue of these for our own use, to add to the ones already in the style?

Or you can click the smooth option on the fractalize popup menu

Or else, resize the scale bar AFTER you resize everything. And I use Remy's SCALEDRAWING command (not official CC3+ command, unfortunately - it has always worked brilliantly for me, and takes care of bitmap scaling as well.

Here is the bit he wrote about it in his dissertation on scaling. (SCALE MATTERS, May 2018)

The Automatic Option

Because rescaling a map is actually a lot of steps, especially if you need effects and fill rescaling too, I’ve created a CC3+-addon to do all of this automatically, you only need to determine the scale factor.

To use it, download the file from this address, and put the .dll file from the .zip inside your CC3+ installation directory (C:\Program Files (x86)\ProFantasy\CC3Plus by default).

You’ll also need to have the Visual C++ 2017 runtime installed on your computer. You may already have this, but if you don’t, you’ll get an error message when starting CC3+ with this .dll in it’s directory. Download from the official Microsoft download site, you’ll need the 32-bit version (vc_redist.x86.exe)

After installing the .dll and the Visual C++ runtimes (if required), you can run the command by typing SCALEDRAWING on your command line. The command line will then ask for the scale factor, which you can provide either as the number, or the calculation as with the non-visual scale command. Once you hit enter after providing the scale factor, the command will take care of the rest. Note that it doesn’t update the display when done, so simply hit the Zoom Extents button after running the command. The map should look visually identical to what it did before, as this command handles the scaling of entities, effects and fills automatically, only way to see that the command did anything is to measure distances again after running this command (and AFTER hitting Zoom Extents). Because it doesn’t do any screen updates, it should also be lightning fast, but remember, you won’t see the result until you hit Zoom Extents. If you hit Redraw instead, you can easier see the result of the scale operation, because this leave your current zoom intact.
