One of the more common questions from CC3+ users is about how to extract a region from a large-scale map and develop this region as a more detailed local map.

The basics for doing this is already explained in the User Manual that comes with CC3+, but for this article, I am going to go a bit more into detail and explain the various tools and processes involved in doing this.

The basic principles behind this operation is to create a new map of the desired size, then copy over the entities from the existing map, trim down these entities to fit the new map size, and finally add additional detail to the new local map. Let us explore the tools and procedure for doing this.

The main tools you’ll need for doing this is Clipboard Copy, Trace, Break and Split, as well as some minor Node Editing.

Let us get started. For this article, I’ll use the example map from the User Manual. You’ll find this map in @Tutorials\UserManual\Example.fcw (remember that the @-sign refers to your CC3+ data directory). My goal is to take the area marked with the red rectangle and develop that into a local map of that area. The marked area here is 30 by 20 miles.

Note that all images in this tutorial are clickable to see higher resolution versions to more easily see what the text describes.

If you are new to this, I also highly recommend loading up the same tutorial map I use and try to follow along with this tutorial, exporting the same area, rather than try directly on your own map. Following along on this map lets you more easily see that things happens the way I describe them, and lets you build familiarity with the tools before starting on your own map.

There is also a video accompanying this article, showing me perform the steps described herein. Note that this video is not intended as a stand-alone video tutorial, but rather as a visual aid to help you see how things are supposed to work. You do not need to watch the video to take full advantage of this article, it is completely optional.
