This blog posting by Remy Monsen might be worth reviewing, as it will allow you to create an image of whatever you wish that looks as if it's been cut into the surface involved.

Looks good.

Obviously, the Empire of the Sun Annual would work nicely for a map of this kind, based on your sketched style, but that wouldn't provide nearly so many building/structure options. For clouds, you might try the cloud symbols in the Alyssa Faden Annual. I'm not sure there are other separate cloud symbol options, although SS6 does have some chimney smoke plumes (they look a bit too smoke-plume specific to be ordinary clouds, however, unsurprisingly!).

Might be worth thinking of moving the mountains further back overall, as they don't look quite right where they are now; too sharp and clear. Maybe add a misty vale in between the building and mountains/trees, and/or just add some mist (transparent irregular polygons of white/pale grey) to fade them a little, and give the impression they're more distant.

Ctrl + F should do it, I think. It's the same command as Tools -> Drawing Aids -> Toggle frames using the drop-down menus, because what you're doing is toggling the frame (thin white line) options to show where the nodes are on a line.

Thinking about the late-stream discussion regarding using the "normal" Mike Schley city symbols to create a top-down map, and then the isometric ones to show a pictorial impression of the place on the same map, with Ralf's comment about using vignettes to highlight important individual places within the settlement similarly, brought to mind the Middle Earth poster map prepared by Pauline Baynes (Tolkien's only approved artist during his lifetime). Digging around online, I've come up with this reasonably high-res version of the original on the Museoteca website, which shows why it came to mind. I used to have a copy of the poster, sadly lost somewhere along the decades since, though it remains strong in my memory!

Yeah, nothing with computers is ever easy, is it, Jim? 😏

@Mike Vermilye - I've just done a very quick test new map with my own reinstallation, and am not seeing the problems you've mentioned. However, I didn't do an uninstall, I just deleted the files and folders that Ralf referred to:

Once I'd done that, I simply installed the replacement Monkey Frog Annual as new.

I'd suggest going through the three places in Ralf's list, removing both any surviving Silverman AND the Monkey Frog versions, and then try a fresh installation of the new Monkey Frog version of the Annual, to see if that resolves things. Failing that, you'd probably be best advised to contact ProFantasy support (through your account page) - unless someone else leaps in here with an alternative. I am NO expert with computers, so that might be your better option now!
