Editing a Node
You can move a node in a node topology, or move a node at the end point
of a link in a network or polygon topology. Moving the node at the end point
of a link also moves that end of the chosen link. Edits to nodes and links in
a polygon topology change the centroid, the area, and perimeter values.
NOTE This functionality is for drawing objects only. There is no equivalent for
geospatial feature data.
When you move a node, AutoCAD Map 3D checks its new location.
■ In node topologies, if there is an existing node in the same location, you
must specify which node to keep.
■ In network or polygon topologies, you must specify whether to join the
links and which node to use to join them.
You can also delete nodes. For more information, see
Deleting Links, Nodes,
and Polygons
(page 888).
If you're working with a network topology, you can also modify the
resistance
(page 850) of nodes.
Deleting one node that indicates adjoining links creates
a single link.
To turn an explicit node into an implicit node, unload the topology, delete
the point or block representing the explicit node, and then reload the topology.
To turn an implicit node into an explicit node, first insert a block or point at
the implicit node point (use an Intersection or End snap to position the block
accurately). Then, if you are working with a node topology, right-click the
topology name in Map Explorer. Click Add Node. You cannot use the Insert
