You can recalculate the lengths of line objects, for example of links, connectors and line routes, after making manual adjustments in the network or changes to the network scale.
|
Notes: The lengths are only calculated correctly if your network has a length-preserving (= metrical) coordinate system (Selecting a coordinate system). If you change the number of decimal places or the network scale, the link lengths and the connector lengths will change, too. Due to the changed length of links, the link impedance and thus the assignment result may also change. |
1. From the Network menu, choose Network settings.
The Network settings window opens.
2. Select the Co-ordinate system tab.
3. In the Lengths section, select the desired options.

Description |
|
Recalculate lengths of links and connectors |
The lengths of links and connectors are recalculated on the basis of the coordinate system. |
|
Recalculate line route length data from link lengths |
If this option has been selected, in addition to links and connectors, the lengths of line routes are recalculated. |
|
Consider only active links, connectors, line routes |
|
|
Calculation method for links |
Use direct length If the option is selected, the link lengths are determined based on the direct distance between the two nodes. Use intermediate points If the option is selected, the distance lengths are determined from the actual course of the link. |
If this option has been selected, only active links, connectors and line routes are considered.
If this option has not been selected, all links, connectors and line routes are considered.4. Click the Recalculate button.
5. Confirm with OK.
The lengths are recalculated.
