There are many things that sets CC3+ apart from other graphics and mapping programs. One of these differences is the size of the mapping area. In most programs, when you start a new file, you specify a size, and you get a canvas exactly that size. If you try putting something halfway outside the edge, like a symbol or equivalent, the spillover is simply lost. In CC3+ however, this is completely different.
CC3+ doesn’t operate with a fixed sized canvas, for most practical considerations it is infinite. There’s nothing preventing you from placing a symbol entirely outside the map area if you so wish, simply because your map only occupies a small spot on that almost infinite canvas. But if the drawing area is of infinite space, how do we determine the actual size of the map? And why do our drawing tools seem to only draw within the map area?
To understand this, we need to look at the map border. When we talk about map borders in CC3+, there are actually two different things we may be talking about. We might be talking about that nice decorative frame around your map. This is known as the decorative map border, and it is just that, decorative. Some map styles have a very elaborate decorative map border, while others have a much more spartan one, sometimes even just a simple line. It doesn’t have any functionality, it is just there to give your map a visual frame. Then we have the technical map border. This is what actually defines your map’s size on the canvas, and all tools that have a restrict to map border option, like drawing tools and bitmap exports work with this one. Usually, it will overlap in location with the decorative map border, but it is the technical map border that provides the functionality.
