When you create a polygon topology, use this dialog box to select the nodes
you want to be part of the topology.
To create a polygon topology (page 836)
Click Create tab ➤ Topology panel ➤ New.
Nodes are useful when performing some types of analysis. You can select all
nodes in the map or select them manually. You can also filter (restrict) node
selection to a subset of nodes, in which you include only the nodes that are
on specified layers, are of specified block types, or in specified object classes.
Node information is stored as object data and saved with the map. Each node
is given a unique ID number, which is automatically processed whenever you
use a topology command.
Select All
Include all nodes that meet the filter criteria.
Select Manually
Include only the nodes that you manually select in the map. Click the Select
Objects to select the nodes. Only nodes that meet the filter criteria will be
selected.
Layers
Specify the layers to use to filter (restrict) node selection to a subset of nodes,
in which you include only the nodes that are on the specified layers. This
filter is used for both automatic and manual selection of objects. To select
from a list of layers in the map, click Select Layers. To use all layers, enter
an asterisk (*) or leave the box blank.
Block Names
Specify which blocks to search for nodes to be used in the topology. To
search all blocks, enter an asterisk (*) or leave the box blank. To select from
a list of block definitions in the drawing set, click Select Blocks. To select
point objects, select ACAD_POINT from the list.
Object Classes
Specify the object classes to use to filter (restrict) node selection to a subset
of nodes, in which you include only the nodes that are in the specified
object classes. To select from a list of object classes in the map, click Select
