WFS data servers provide the ability to access vector spatial information via a remote connection. Although you can use 'Spatial Manager' User Data Sources (UDS) to access this type of servers, it is interesting to know that these servers return data in GML format
'Spatial Manager' for CAD applications (AutoCAD, BricsCAD and ZWCAD) will enable you to perform territorial analysis processes based on the geographic objects by using selection tools and Properties of the graphic objects themselves. For a great amount of these processes you will not need to generate topologies or calculate complex topological operations
