This command will not be supported in future releases. This is the old command for adding a node to a topology. The new command is MAPAN.
Use this command to add a an existing block or point to a topology while maintaining the integrity of the topology information.
Respond to the prompts:
Enter the name of the topology to add the node to. To display a list of all loaded topologies, enter ?.
Select an existing block or point.
You can use this operation to create a new block object at the location of an existing implicit node. MAPNODADD prompts you to select the new block or point object.
You cannot add a new node to a topology with this command. To insert a node on an existing link, use the MAPNODINS command.
