As you yourself conclude, the main issue is that many of these things are defined as percentage of view width, while the actual preview window is a fixed size, so this can happen with extremely large maps like this.

So in short, nothing is broken, just a view issue.

You can actually change the size of the preview windows, if you hit that advanced button in the drawing tool window, you'll have access to the sample width setting, which is the size of the preview, just bump this up a few notches. Do note that this is a per-tool setting.

At this stage, the bitmaps may look more pixelated than desired too, so you may wish to use :CC2RESMODE: to force a higher resolution for the display (Note that this can affect performance)

It is not possible to call such things from the command line. CC3+ wasn't written with batch processing in mind.

You can talk to CC3+ from an external program using the Intercom interface however, which means you can send commands from an external program which are then run as commands inside CC3+. I don't have a tutorial for that on hand. Some information can be found in this old blog by @saunderl http://cc3-developer.blogspot.com/search/label/Intercom

The second alternative is to make your own XP which opens up a lot of possibilities for expanding CC3+ with your own code. I don't think you'll be able to implement more command line options or prevent the gui from loading though, those things are (most probably) beyond what an XP can do.

One way you could approach it is to decide the size of the average house. A medieval or earlier house for commoners were usually a tiny affair, often no bigger than my living room. Then, based on your house size, so you can used that against the sketch to determine size.

The issue here is with the wide lines. Unfortunately, symbol fills cannot have lines with a width other than 0, nor can they have solid filled polygons.

If you change the line width to 0, it should work, but that probably won't be the look you are after then.

You're probably better off making that as a png image instead and using it as a regular bitmap fill instead.

The WBC is a collection of previous published articles. They have been cleaned up, organized, and formatted for publishing in a pdf format, but they don't contain any new information from the original articles. It's a mix of articles that talk about word building in general, and articles that focuses more on the CC3+ side of things.

There's also some additional tutorials bundled with it which I haven't been able to look over, but I believe those are sourced from the annuals.

This map is now in the atlas. Thanks Quenten.

Which sheet is that? You cannot hide the the sheet CC3+ wants to place the symbols on. For example, most regular symbols goes to the SYMBOLS sheet, so that will be unhidden whenever you pick a symbol from the symbol catalog (but the screen isn't immediately redrawn, so it won't be visible until you do an action that redraws the screen, such as zooming in/out)

If this is what's happening for you, you can handle it in two ways. Either turn off the option "Symbols choose their own sheet" from the options button in the symbol catalog, OR make sure your current sheet is named something that starts with the word SYMBOLS since CC3+ will then use that instead of the main SYMBOLS sheet.

(Note that some special symbols defaults to another sheet than SYMBOLS, they would show the same behavior with whatever sheet they were set to go on)

You can't zoom to a specific % because that concept doesn't really exist in CC3+. CC3+ is CAD software, and the content is always rendered to whatever size you select, there isn't a "full", "print" or "actual" size.

With an image editor, zooming to 100% makes sense, because that means that each pixel in your image is being showed as the same size as a pixel on your screen, but CC3+ maps aren't expressed in pixels.

For print size, that really depends on what scale and paper size you want to print at. As with showing on screen, print isn't a fixed size, CC3+ renders the output to match your print settings.

Considering your screen is likely to be much larger than a sheet of paper (unless you are working on a laptop screen), zooming to show the same content that will be on your paper wouldn't really give a perfect view of how it looks on paper anyway, since the paper is so much smaller.

You can run the LISTIMAGENAMESDWG command to do this. It will list all the images in a drawing, and tell you if it is a fill style image (bmpsty) or a symbol/inserted image (pictr2)

You can also use my custom command that list images sorted by addon. Note that the accompanying data file is a bit out of date, so a lot of files will be identified as unknown add-on.

Have you remembered to add the Wall Shadow, Point Light Finalize effect? Lighting doesn't start working until this effect have been added.
