Create Polygon Topology - Select Nodes dialog box
 
 
 
NoteThis functionality applies only to drawing objects.

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

Click Create tabTopology panelNew. At the Command prompt, enter maptopocreate.

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 Object Classes. To use all object classes, enter an asterisk (*) or leave the box blank.

Cancel

Close the dialog box without creating the topology.

Back

Display the previous dialog box in the list.

Next
Finish

Create the topology using the current settings. The Finish is available after you enter a valid, unique name for the topology.
