I was working on an assembly video for a product my team designed and started making this tool to easily generate and manipulate cables that exist in the real world. The scope of the tool quickly grew and now I'm releasing it as an extension (add-on) for Blender!

You can either create a 'Cable Curve' object via the Curve catalog in the 'Add' menu (Shift + A) or add the 'Curve to Cable' modifier to an existing path object. You can customize your cable in the properties window with an extensive option set.
