You can bring in web-based features that have been published to a public web server using the WFS (Web Feature Service) open standard developed by the Open GIS Consortium (OGC).
To bring in features from WFS
Click the down arrow to choose from a list of sample and recently-used URLs.
Default Version specifies the highest version number to start the client and server negotiation.
If you select a version number, AutoCAD Map 3D toolset uses that version to negotiate with the server and then uses the next available version number if the server doesn’t provide the service of the version you selected.
Any proxy settings you make are remembered if you re-open the connection window.
To bring in features from WFS
If this feature source contains only a single feature class, that feature class is selected automatically. If it contains multiple feature classes, you can do either of the following:
If a feature class contains multiple geometry types,and you select the feature class itself, all geometries are added. To add a subset of geometries, hold your cursor over the feature class name to see the Show Geometry button. Click Show Geometry to see each geometry as a separate choice. Select the ones you want. Each selected geometry is added to map as a separate Display Manager layer.
