Define Manual Cable Cuts - Intergraph Smart Electrical - Help - Hexagon

You can manually define cable cuts for a specific cable. This way you can assign predefined cable cuts to a cable drum in the Assign Drums to Cables Wizard or in the Cable Drum Common Properties. Also, on the Design Data tab of the Cable Common Properties, the software indicates the number of splices in accordance with the number of cable cuts that exist for the given cable.

This feature is not available for cables that have already been assigned to drums.

1. In the Electrical Index, open the Common Properties of a required cable.

2. Select the Design Data tab.

3. In the Drum assignment group box, select the Cable Cuts button.

4. On the Cable Cut Definitions dialog, select Add.

5. Define the values for the new cable cut:

   • Select in the Cut Item Tag box and type a new cable cut name if you want to rename the default name.

   • In the Cut Length box, type the length of the new cable cut. The total length of the cable cuts must be identical to the cable actual length.

6. Select the Retain manual cable cuts for drum wizard assignment check box to make the cable cuts available for selection on the Select Cables page of the Assign Drums to Cables Wizard.

   

   If you clear this check box after defining cable cuts, the existing cable cuts will not be included in the list of cables on the Select Cable page of the Assign Drums to Cables wizard. Instead of the cable cuts, the entire uncut cable will appear marked by an asterisk. The software will recalculate the cable cuts and if needed automatically delete or recalculate them once the assignment process is completed by the wizard.

   To retain these cable cuts, select the Common Properties button on the Select Cables page of the wizard and return to the Cable Cut Definitions dialog where you select the Retain manual cable cuts for drum wizard assignment check box. When you return to the wizard, the information on the Select Cables page will be refreshed and the cables marked with asterisks will be automatically replaced with their cable cuts. Any change made in the Cable Common Properties automatically refreshes the data on the Select Cable page of the wizard.

7. Select OK.

• If you increase the cable actual length and select the Retain manual cable cuts for drum wizard assignment check box, the software automatically adds a cable cut to account for the added length.

• If you decrease the cable actual length and select the Retain manual cable cuts for drum wizard assignment check box, the software automatically deletes a cable cut to account for the extra length. The deletion starts from the bottom of the cable cut list upward.

• To delete a cable cut, select a row and then select Delete. This action is not possible if the cable cut is assigned to a drum. Unassign the cable cut from its drum and then delete it if needed.

• You cannot change the cable cut length if the cable has been assigned to a drum.

• You can unassign a cable cut from a drum by selecting a cable cut and selecting Unassign From Drum.

• All the values in this dialog are read-only for a cable that has been locked to a drum or installed and you cannot add, delete, or change a cable cut length for such a cable.

• The following is an example of a typical workflow when working with cable cuts:

  1. Create a cable.

  2. Define the cable design and routing length or get its length from Smart 3D, which establishes its actual length.

  3. After the cable actual length has been established, determine whether there is a need for splicing and define the required length of the cable cuts.

  4. If the cable is longer than the normal drum maximum capacity, you can decide whether you need to define the exact length of each cable cut or whether to use the Assign Drums to Cables Wizard to cut the cables automatically.

  5. If the cable is shorter or longer than the maximum drum capacity and you need to have splices at specific lengths, then you will manually define the cable cuts so that cable spicing can take place in appropriate places.

  6. Create the first cable cut, name it, and define its length.

  7. Create the rest of the required cable cuts until the total length of all the cable cuts is identical to the cable actual length.

  8. After all the required cable cuts have been created, you can assign them to a cable drum using the Assign Drums to Cables wizard or the Cable Drum Common Properties dialog.
