There is no method (to my knowledge) of having two cables with a shared conductor spool (i.e., CABLE_SPOOL_1, and CABLE_SPOOL_2, both use a similar conductor spool CONDUCTOR_SPOOL_1. As of right now, both cable spools CABLE_SPOOL_1 and CABLE_SPOOL_2 must have independent definition of that same conductor. Therefore, the parameters associated with that conductor must be explicity called out in the logical data, or explicitally created by hand, for each cable.
Creating a method to have common conductor, as well as a method to edit/add/remove conductor spools from a cable spool within the "Spool Manager", would simplify NWF/logical data and modifications to cable design, and could be used to help identify exact required cable lengths "per spool", to be used for purchasing.
One piece of proof towards the fact that this is currently missing functionality: In Pro/TOOLKIT, the object ProCableType includes definition for PRO_CABLETYPE_CONDUCTOR... however when attempting to create a spool for PRO_CABLETYPE_CONDUCTOR using ProSpoolCreate, anerror PRO_TK_INVALID_TYPE is consistantly returned. So, if the above functionlity is added, the capability to also create conductor spools via Toolkit would be appreciated.
