Calculate Cable Lengths |
ConnectCAD > Documentation |
The Calculate Cable Lengths command verifies the cable network connections and calculates the lengths of the circuits/cables in the network, including Spotlight cables. It determines the beginning and ending points of circuits across the cable network, based on connectivity from the schematic and the equipment associations from drop points (including 3D racks). It assigns circuits to each segment of the cable network so that it can display each circuit's cable length.
It identifies and flags errors, such as missing sockets, unassigned drop points, and missing, unassigned, or duplicate equipment items.
If circuits were assigned to cable objects by selecting them according to the Cable Run ID, the cable path segment will already have been updated by the cable. These circuits are skipped.
When Auto is selected for the Cable Length in the Object Info palette of a selected circuit, the Calculated Cable Length is estimated automatically. Use this command to enter values to account for expected extra cable lengths that are needed to place circuits into a rack.
To estimate circuit lengths automatically:
To calculate the length of only selected cables, select the cables (or circuits).
Select the command.
The Cable Length Options dialog box opens. Enter the allowances to account for extra cable lengths needed in a rack, and determine whether to calculate all cables or only selected ones.

Click OK to calculate estimated circuit lengths in the current layer, accounting for extra cable needed as indicated. In the Object Info palette of a circuit or a Spotlight cable object, the calculated cable length displays. The length can be reported in a cable report, with an estimate of the required lengths of cable for the entire project.
If an error occurred, some circuits may not have been properly identified for the calculation. The circuits are highlighted for identification and correction.
