NOTE This procedure is for drawing objects only. There is no equivalent for
geospatial feature data. However, you can use buffers to analyze features by
proximity and perform overlay analysis on two geospatial feature layers. See
Buffering Features in Your Map (page 1308)and Overlaying Two Feature Sources
(page 1316).

Creating Topologies
Topology defines how map features represented by points, lines, and polygons
are connected and how to account for their adjacency. For example, topology
can show that parcels do not overlap, or that delivery routes follow roads.
Using AutoCAD Map 3D, you can create node, network, or polygon topologies.
For network topologies, you can specify the direction of movement allowed
for links and the resistance for links and nodes.

proximity and perform overlay analysis on two geospatial feature layers. See
