| Layer Names list box (not labeled) |
Displays the master list of layer names. |
| Create |
Opens the Create dialog, which contains controls that handle the configuration, naming, and creation of a network layer. It enables the user to perform the following configuration tasks:
- setting the SQL statement for edge costs and edge filters, and
- setting the SQL statement for node costs and node filters.
|
| View Costs |
After selection of an edge or a node, the Node Costs dialog or the Edge Costs dialog opens, which enables viewing the costs associated with nodes and edges. It is possible to modify the values and click update, which updates the costs associated with the nodes or edges. |
| Trace |
Opens the Trace dialog, which enables to perform the following types of analysis on existing layers:
- Shortest path — which measures the shortest path, with the least resistance, from point A to point B
- Radial Search — which measures the distance in a specified circular path around a given point (with the least resistance). Edges that are not completely within the search distance are segmented and the part that is within the search distance is included
- Trace Forward — which measures the edges and/or nodes that are downstream from a specified point
- Trace Back — which measures all the upstream edges and/or nodes from a specified point
Note: A Trace can originate from anywhere on an edge.

| Display |
Displays the network layer highlighted in the Network Analysis dialog. |
| Add |
Opens the Add dialog. |
| File > Exit |
Closes the Network Analysis dialog. |
| Options > Draw Arrows |
If on (checked), displays the direction (using arrow heads) of the line based on the order of its vertices. The original line direction is determined by how the line was (originally) digitized or drawn. However, it is possible to reverse the line direction using the Change Element Direction tool in the Curves toolbox. Default is On. |
