Creating Spools
A spool defines various parameters for a wire, cable, or sheath. A spool of the respective type must be defined or available before a wire, cable, or sheath can be routed in a cabling design. Cabling utilizes the spool information to create and regenerate the 3D graphical representation.
The Electrical Parameters dialog box enables you to create and modify spools. Any updates made to the Spool Parameters after the wire, cable, or sheath are routed will be reflected in the 3D graphical representation model after it is regenerated.
While routing a wire, cable, or sheath using the schematic information from Creo Schematics, the spools are automatically created. Modifying the automatically created spool information causes a mismatch between the 2D logical data and 3D design. To avoid this mismatch, PTC recommends that you make changes in Creo Schematics and then re-import the information. Re-importing logical data resets the spool information according to the information defined in the schematic.
Spool Parameters
The following table lists all system spool parameters. The table also lists which parameter is required, optional, and recommended for the specific type of spool. You can also add a user defined parameter to define specific requirements.
