When you create a polygon topology, use this dialog box to select the nodes you want to be part of the topology.
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.
Include all nodes that meet the filter criteria.
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.
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.
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.
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 Object Classes. To use all object classes, enter an asterisk (*) or leave the box blank.
Close the dialog box without creating the topology.
Display the previous dialog box in the list.
Click to display the Create Polygon Topology - Create New Nodes dialog box.
Create the topology using the current settings. The Finish is available after you enter a valid, unique name for the topology.
