You can create a drawing layer in Display Manager that includes all the objects in a topology.
To bring in drawing objects based on topology
AutoCAD Map 3D creates a layer in Display Manager for each topology you select.
If you combine the layers in a group, you can turn the display of the group on or off.
The new layer appears in Display Manager. All objects in the selected topology are included in this layer. If you selected multiple topologies, multiple layers are created. To see the objects, you may need to zoom to the drawing extents.
