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.

You say reinstalled, but did you actually install the update, or reinstalled using the original CC3+ installer? The CC3+ installer will only fix CC3+ itself, so running a repair install using that won't help with SS1 problems, but the updates contain the update files not just for CC3+ itself, but for all the add-ons and stuff too. This is why it is important to install the update after installing any new add-on, even if your version number is already at the latest.

If you already did install the update and it didn't work, you should contact tech support. You'll find the form by logging in to your registered user pages.

I don't remember what Ralf did in that video, but for curves, Offset is your friend.
