Am I understanding you right here that each sheet is one floor, so that all the floors are in the same map file?

In CC3+, because of things like sheets effects and such, maps tends to use a lot of sheets, so it is generally better to use one map per floor. Although it is possible to keep it as one map too, but then the macros hiding the sheets must be updated to hide the complete set of sheets. With some nice naming you can do this rather easily by taking advantage of the HIDESHTF and SHOWSHTF commands which hides and show sheets by a wildcard filter, so for example all sheets for floor 1 could be named FLOOR1_SOMETHING and so on.

The easiest way to use textures (fill styles) from another style is to first make a blank dummy map in the style containing those textures, then in your actual map, go to Draw -> Insert file and pick your dummy map and hit ok. Once you return to your map with the dummy map on your cursor ready to place, just hit escape immediately to stop placing it.

You're in for a lot of discovery yet :)

Yes, just hold down the control key and click on an entity to deselect it.

Another thing when it comes to text, make sure to pick a font available on your computer. The first list shown in the Text Properties dialog are fonts defined in your map, and may include a font you don't have (Click 'More fonts' to access the list of fonts on your computer). If you pick a font you don't have, CC3+ will render a replacement font, usually Arial, which could result in no visible change if the font was already rendering using Arial.

Also, you said you used edit properties to check sheet/layer. Be aware that the values listed here are NOT the current properties of the entity picked, but rather the currently set properties (as seen on the status bar) used when creating new entities. Change Properties/Edit Properties is not a way of checking an entity, you need to use List as Jim said to do that.

First of all, don't do that, it's not going to do anything for you at all.

The problem is related to the fill styles defined in your current map. The reason those tools show up all wrong is because you don't have the required filled defined in that particular map.

Tools are not meant to be changed on the fly like that. Every map style have it's own set of drawtools available to it, and by default, tools from other styles will not work in the map. You can work around that by importing the fill styles as Sue showed, but out of the box, it is completely normal that the tools show up there when you try to pick another style than the one belonging to the map. There's nothing wrong with the tools, it is just that the fills they requires is not defined in the open map, which makes all of them display with the currently select fill style (see top right of the CC3+ window) instead of the intended fill (since it is not defined in the map)

If you want to use "foreign" drawtools in a map, follow the guide Sue posted above for how to import the correct fill styles into the map. Then the tools will work. And if you have deleted fills from the fill style dialog, you can just repeat the procedure to import them again.

Ah, I see. I kind of guessed the cafe was the kitchen, but I couldn't really how the rest would work out.

Do remember to tell your neighbour that he needs to buy a ticket to get into the ares you stole from him. Zoo's aren't free you know.

You shouldn't add grids directly to wizard template maps, precisely because the way it is scaled when you decide map size.

Either use the option in the new map wizard to create a grid when you create the map, or if you use the same size map all the time, create a new map from the wizard template in the appropriate size, add your grid, and then save that map as a temple among the non-wizard templates. (i.e. not inside the Wizard folder). You can then find that template by selecting a pre-defined template instead of decide settings yourself and make all future maps from that.
