command will not be supported in future releases. This is the old
command for adding a link to a topology. The new command is MAPAL.
Use this command to add
a link to an existing network or polygon topology while maintaining
the integrity of the topology information.
Respond to the prompts:
- Enter topology name (? for list) <toponame>:
Enter the name of the topology
to add the link to. To display a list of all loaded topologies,
- Enter first point:
Enter the coordinates
for the first point of the line, or select the point.
For information about this
prompt, see the PLINE command in the AutoCAD help.
You can use MAPLINKADD
to add a link in three ways:
- In space (connecting no existing nodes).
Two new nodes are created at the link endpoints in space.
- From one existing node to a point in
space. A new node is created at the end point in space.
- From one existing node to another existing node.
A topology must have
a node at the end points of all link objects. This node is part
of the topology data structure and is assigned a topology ID. However,
a node can be implicit (referenced in the topology data structure) or
explicit (a physical object in the drawing). Use the MAPNODADD (Add Topology Node command) or MAPNODINS (Insert Topology Node command) command
to create a new node.
When you add a link to
a topology, AutoCAD Map 3D creates a node when necessary. If the link
joins two existing nodes, no new nodes are created. Remember these
features of nodes and links:
- A node can reference many links.
- A link can reference only two nodes.
- Only one node can exist at a specific
If the new link splits
an existing area in a polygon topology into two areas, AutoCAD Map 3D creates
a new centroid and updates the existing centroid.
