Deleting Links, Nodes, and Polygons
You can delete a node in a node, network, or polygon topology; a link in a
network or polygon topology; or a polygon in a polygon topology. When you
delete nodes, links, or polygons, object data and external database links may
be lost.
WARNING Both the topology information and associated objects are deleted.
NOTE This functionality is for drawing objects only. There is no equivalent for
geospatial feature data.
■ Deleting a node shared by two links joins the links together. First and last
point information on the resulting link is updated.
■ Deleting a dangling link deletes the dangling end node.
■ Deleting a link deletes any associated nodes, unless the link is also part of
another topology or the nodes are referenced by another link.
■ Deleting a polygon deletes the centroid and all references to it in
surrounding links, unless objects are part of another topology or are
referenced by another polygon.
