How to Use Topology to Convert Points to a Polygon on Map 3D 2011

AutoCAD's Map 3D 2011 is a computer aided design, or CAD, application that enables users to create maps based on geographic information system, or GIS, data. Users can import data from GIS devices and plot it on custom maps, or opt to add point and lines by hand. And if you'd like to specify new boundaries on maps, you can use Map 3D topology engine to convert imported point data into polygons.
