AutoCAD Map 3D 2013 New Feature: Multiple Maps and Viewport associations

Ever wanted to make a layout that had an inset map and a main view, both showing different FDO or AutoCAD layers?

Of course you have! And now you can.  Map 3D will now allow the creation of multiple maps, which can then be associated with separate viewports.

1. First, you'll need two separate maps.  Create a map as you usually would - I started with an overview map for context
2. Then I made a second, more detailed map.  To make the second map, click the Maps button (new in 2013, then select New and give it a name, then create the new map. 
   
   
3. Now, make a layout with two viewports, one much larger than the other.
4. Pick the smaller layout, and you'll see that the Layout Tools ribbon turns on.  Select Display Maps, and then pick your overview map.  Repeat for the larger viewport, using your detail map.
5. Your end result will be two viewports, with different maps at different scales, both of which can be independently edited.
6. Spruce it up with a legend, and you'll have some great looking maps!

Note: ACAD objects will be present in both, and the extents of both will be the same.  Mousing over the viewport will display the Map name in the corner of the viewport for reference.  More on legends, north arrows, and scale bars coming soon.
