Note that the SS3 Pro template require proportional scaling. This is set up this way due to the legend at the right, it would look weird indeed if it was scaled arbitrarily. So the new drawing wizard enforces a 5:4 ratio on that template. So 17 by 11 is not a valid size for this particular template.

You'll notice how the width and height change in relation to each other if you just exit that particular input field instead of directly clicking the next button. Change one, and once you exit the field, you'll see the other update to the appropriate value for the constrained ratio.

1. To get a circle into a path/poly, first :CC2SPLIT: it, then use line to path on it.

2. I don't think there is a template with this grid, this was drawn specifically for that map. If you have the 2018 annual, there is a star charts issue which includes a similar grid in the template, if not this exact one.

Placing circles concentrically can be done a bunch of ways. Either with the center modifier (I don't understand why you find it unreliable, it always works for me for normal entities. I don't know if it correctly handles things like multipolies, and it can't handle symbols correctly which are complex entities made up from several others.), or by using snap and using a common center point, or by just typing in the coordinates for the center of each circle (and make them the same obviously), or even by placing another entity first and use for example endpoint. To make the sizes of the circles increase linearly, either use snaps, or type in the radius manually, increasing it by the desired number for each circle.

Lines can be easily drawn using radial coordinates. Draw them from the center first, then trim them to the inner circle. You can also use array copy to distribute them around a circle, or even Symbols along.

The numbers are just text with a rotation matching the angle of the line + 90, with a low center as text justifciation, and placed using the endpoint modifer.

It might not be a simple one-click solution, but with all the precision tools in CC3+, drawing grids like this is one of the things it excels at.

If you save it as a "Cosmographer Template" you'll get the correct hex setup automatically. Well, correct if you like the size of the hexes it gives you by default I suppose.

600 dpi is just 4950 by 7050 pixels for a full standard page, that's less than the images I render for the atlas.

CC3+ doesn't do CMYK, but image files can be converted in many image editors. Of course, since CMYK is designed primarily for print purposes, you need a properly calibrated screen to really be able to see the image the exact same way it will end up on the printer.

City styles aren't really made for showing interior details, so it doesn't work like that by default.

However,there isn't anything preventing you from drawing building interiors, and then but the building sheet on top of them. So, with the building sheet visible, it will cover up the floorplans and look like a normal city, and with the building sheet hidden, you will see the floor plans. All you need to do is to set up proper sheets to draw your floor plans on, and import the required fill styles into your map.

A word of warning here though, mapping the interior of every building in a large city is time consuming, and also results in a lot of entities that can cause CC3+ to slow down. You can avid the latter partially by making sure the interior sheet is hidden when it is not in use (as in actualy hidde, not just covered up by the buildings sheet). For a smaller place, this may work perfectly fine, but I don't recommend it for larger cities.

Instead, I would make some detailed sections of the city as maps like this.

Also note that CD3 can automatically take a building symbol and make a floorplan from it on it's own map. This map is then linked from the city map so you can just click on it to go to the floor plan map. This is the preferred way of making florplans for houses. Note that it only generates the outline of the floorplan, it won't greate a fully furnished plan for you.
