When you assign cables to cable drums, there are specific rules that govern how the software determines whether it is possible for you to assign a given cable to a drum. These rules apply whether you make the assignment from the Cable Drum Common Properties dialog or from the Cable Common Properties dialog.

The following rules apply:

  • For each cable, Smart Electrical uses the Actual length value.

  • The value under Total actual length assigned is the sum of the actual lengths of all the assigned cables.

  • If assigning a given cable would cause the Total actual length assigned value to be greater than the value that you set under Maximum cable length, the software does not allow the cable assignment.

  • You can make allowance for cable cutting error by entering a value under Drum spare percent. The software includes this percentage in the Total actual length assigned value.
