Thanks. I'll put it in queue, but as with other SS6 maps I am going to delay including them into the atlas until SS6 is officially released in case the release version sees any changes from the prerelease.

Unless you need to spend a lot of that on a graphics card (which won't do anything for CC3+, but if you plan to use the computer for gaming, you may want one), the 13th generation Intel i5's are pretty good, both in actual performance, and value for money. If you can get an i5-13600K, I would go for it.

Recommend getting 16GB of RAM. CC3+ itself can't use more than 4, but your OS and other programs want their chunk of it, so 16 allows CC3+ to get it's fill. Probably best to go with DDR5 these days for the future, but if the budget constrains you, you are better off going for DDR4 ram instead of scaling back the CPU.

I also recommend having a NVMe system drive, and make sure it is big enough to install CC3+ on it. Personally, I recommend 512GB+. CC3+ do use RAM caching, so it won't be terrible on a slower drive, but getting the extra speed is good.

For the rest of the components, get what you can. You don't need a huge PSU (unless you are also getting a powerful graphics card)

Extra storage, more ram is always good.

For abstract symbols like this, there aren't any correct scale to draw them at. So what I usually do is to place another symbol I imagine will be similarly sized down into the map (Such as the explosion symbol from your example above) at scale 1.0, then I use the distance tool to measure the sizes, and then use these measurements as a guide for my new symbol.

Just remember to always work at scale 1.0 when you are creating the symbols. If you place down the guide symbol at scale 0.1 and measures it and creates the new symbol based on that, the new symbol will be 10 times too small.

Unfortunately, that's a limitation of isometric symbols in any style. They can't be rotated (and still make sense). CC3+ is just a 2D-mapper, so to create a 2.5D style like this, symbols have to be drawn in a special way to create the illusion of three dimensionality by building the perspective into symbol image itself, but that also make the symbols only work when they are oriented the way they were originally drawn.

The Floorplan category is mostly for modern florplans. For fantasy, look under dungeons, and for sci-fi, look under Cosmographer.

From SS1-6, only SS3 have anything under florplans.
