The next compatibility update is here: Symbol Set 3 – Modern is now available for CC3+. Symbol Set 3 provides a variety of styles modern maps: 3 different floorplan styles (two bitmap-based, 1 vector) and two overland styles, one for Ordnance Survey-style topographic maps, the other for modern political maps.
Click the example on the right to see a large-scale version of the bitmap-based floorplan style created by Jonathan Roberts for Symbol Set 3, and click the left image below for an example of the modern political style, based on the work of Brian Stoll. The right image shows an example of the Vector Ordnance Survey style.
If you already own Symbol Set 3, you can simply download the setup for CC3+ from your registration page. If you do not own SS3 yet, you can get a copy here.
The installation of Symbol Set 3 for CC3+ requires the latest update (CC3+ Update 3). Make sure to download and install it from your registration page before SS3.
