To Define or Correct Auto Routing Entry Points

Auto Routing Entry Points are used to select raceway in equipment's proximity that will be considered for cable routing.

Select all the cables by clicking the checkbox at the topmost row from the Cable Manager dialog .
Note: You can select individual cables by clicking the checkbox corresponding to each cable.
Click Entry Points from the Cable group on the ribbon in the Cable Manager dialog.

The Auto Routing Entry Points dialog opens.

Note: Maximum distance is a bounding sphere radius around equipment that is used to identify any raceway that will be considered for cable auto-routing. Which cable tray will be selected depends on segregation criteria and available spare capacity. Bounding sphere radius is used to identify all potential raceways, not to select any specific raceway to be used for auto-routing for selected equipment.
For equipment having positive values defined for Maximum Distance and Max Entry Points #,
1. Right-click on the selected Node, for example, MCC 01 and click Select All from the context menu.
2. Enter the value for maximum distance in the Max Distance field as 10.
3. Enter the value for maximum entry points in the Max Entry Points # field as 10.
4. Right-click on the Node and select Visualize from the context menu.
  
  The raceways within the 10 ft bounding sphere radius are considered for cable routing from the selected Node MCC 01 .
  Note:
  - The maximum distance for the Imperial dataset is defined in feet (ft) and for the Metric dataset in meters (m).
  - These default values are populated from project configuration options UDA settings > Cable UDA.
For equipment having Maximum Distance = 0 or negative value,
1. Select the desired Node, for example, MCC 01.
2. Enter the value for maximum distance in the Max Distance field as 0 .
3. Enter the value for maximum entry points in the Max Entry Points # field as 1.
4. Right-click on the Node and select Visualize from the context menu.
  It shows the nearest routing line and is also applicable for cable routing.
For equipments having Max Entry Points # = 0,
1. Select the desired Node, for example, MCC 01.
2. Enter the value for maximum distance in the Max Distance field as 12.
3. Enter the value for maximum entry points in the Max Entry Points # field as 0.
  Note: If the value defined for the Max Entry Points # = 0 it will show all the possible routing lines in the sphere.
4. Right-click on the Node and select Visualize from the context menu.
  It shows all possible routing lines in the sphere.

The alternative method of selecting/deselecting raceway for auto-routing is by using the Includes and Excludes option.

Select a Node, double-click on the Includes field and then select the icon.
Select the raceway(s) that you want to include for cable routing by selecting their routing lines in the DGN file (use <CTRL> to select multiple raceways), then left-mouse click to make a data point anywhere in the DGN file to get back to Auto Routing Entry Points dialog.
If the selected raceway has an ID, it will be displayed in the Include IDs field.

Sections defined in the Includes field may overwrite the settings in Max Distance and Max Entry Points #.
Click OK to include the selected raceway(s) else click Cancel to discard the selection.
To remove a selection defined in the Includes or Excludes section, right-click on the selection and select Delete from the context menu.
Select a Node, double-click on the Excludes field and then select the icon.
Select the raceway(s) that you want to exclude for cable routing by selecting their routing lines in the DGN file (use <CTRL> to select multiple raceways), then left-mouse click to make a data point anywhere in the DGN file to get back to Auto Routing Entry Points dialog.
Click OK to exclude the selected raceway(s) else click Cancel to discard the selection.
If cable auto-routing has failed, use the filter option from Cable Manager data grid to display only the cables with failed routing and auto-routing entry points.
Make adjustments to the entry points as necessary.
