After a bit of digging around (it's actually SS3, not SS2, which confused at first!), the SS3 Bitmap A and B styles both have wall features like doors, so will cut the walls. SS3 Blueprint Floorplans has no door symbol options, so won't have any wall-cutting tools (so that symbol catalogue comes up as blank).

It looks, though, as if you're actually using the Vector style, as in the Symbols > Modern > Floorplans Catalogue are two vector wall features catalogues Wall Features 31 and Wall Features, both of which have wall-cutting features.

For unknown reasons, using the symbol catalogue icon doesn't call-up either of the Vector Wall Features catalogues in a new Modern Vector Floorplan map I did as a test, so at least I can say it's not just your system!

You can navigate to the symbols manually, or you can add either of those files to your map using the drop down Symbols - Symbol Settings... option, which calls up this panel:

In which I simply added the word "Floorplans" after "Modern" in the "Master filter" box and browsed to the correct FSC file under "Catalog setting specifications", saved that, and the catalogue now shows up when I click the :CC2SYMPATH: icon.

Hopefully, this will help with your mapping.

@Don Anderson Jr. - The line with the horse icon will only show up if you have the various non-ProFantasy symbols from the CSUAC, Dundjinni, Bogies, etc., items installed.

Just finished catching-up with today's video, as I wasn't able to be there for it live.

I've used Character Artist quite a bit over the years, and it was a shame to discover there are no plans to update or expand it, if perhaps understandably so, given it is something of a "luxury" add-on, compared with the primary mapping purpose of CC3+ in general.

Reviewing the video so soon after it was posted means the chat wasn't available to view (it sometimes is lost anyway, if the video is later edited before its final YouTube posting), but I don't think it was mentioned there that there is also the original Character Artist Pro, which has many more drawn-symbol options than CA3, and is much easier to draw your own additions onto, because it uses the far simpler vector drawing style. I suspect many now wouldn't feel it to be "pretty" enough, compared to the more modern hand-drawn version, unfortunately, but it is a versatile tool that shouldn't be ignored - to me, at least!

You should though check your card provider's terms and conditions before carrying out the transaction, as you may find there's a small extra fee to convert the currency (about 3% of the transaction value is common, though not universal). Like Loopysue, I'm in the UK, but have carried out transactions this way for some years for US, Canadian and New Zealand Dollars and Euros, for instance, and the transactions have always been pretty straightforward.

Also, if you're concerned, you can pay through PayPal (even if you don't have a PayPal account), and that shows you exactly how much you'll be paying in your own currency, including the conversion fee (and your card provider shouldn't charge you any extra).

It is a little hard to judge zoomed-in so far, but the toning-down of the blue does seem a definite improvement. There's always going to be a degree of unreality about it, as in most other overland styles, given the textures have to act as terrain markers as well as look pleasing.

The Displacement effect does add a little more (if loose!) reality to the drawing style, and people can always turn it off, if their road lines need to be more traditional, linear route-markers (which is how roads are shown on most maps at this kind of large-scale regional area, after all). Will rivers enjoy a similar treatment?

Textures are looking good. The snow might be a tad too blue and bland overall, though this is tricky, given large-scale snow/ice-fields tend not to look quite this pristine anyway. A couple of the taller mountains also seem to have a dark blue baseline that looks a trifle odd against the snow at the Forum image scaling, but looking closer, those are probably glacier-ends, I think.
