Disappearing parts during overlap happens because the same line overlaps itself. There are several ways to avoid or fix this:

• Don't start drawing at a corner. If the start/end is in the middle of a length of wall you don't need any overlaps
• Build the walls using more than one path. If they are not the same entity, you don't get the disappearing problem.
• Use tools like Combine Path or Path to Poly to combine the lines to make the corners actual corners and not just "meeting points of the ends"

Pick the_CC3+ Mike Schley export setting when exporting from CC3+. Or, if you have defined your own export setting, make sure to use the @Templates\CC3+ Mike Schley.FCW template file in the first page of the export settings.

You may have downloaded the fixed version Ralf just put up to your Mac. The new fixed version does contain the files, and should install them properly.

For those interested in the technical details, the reason for the lines was that when the symfill files didn't exist, CC3+ failed to load them, so it used the default settings. Which happens to be a very simple vertical line symbol.

Some compass roses would be nice also on city/street maps, such as Arthenn and the docks. Looking at the bridge and the parent map, it is clear that north is to the right on the docks map, but this can't be seen from the map itself. Preferable, any map that doesn't ashere to the modern convention of north up should have a compass rose to indicate this (Personally, I like to see them on most map anyways).

Wouldn't mind seeing some scale bars as well, makes it easier to use the maps.

While that symbol is a raster symbol, it is really just some simple geometric shapes. You should be able to easily enough draw that yourself using the circle and polygon tools in CC3+ and define it as a vector symbol. The user manual goes through symbol creation on page 75 if you're unsure of that part.
