This video demonstrates the relative ease of pulling together a custom cable in the Zuken E3 tool. In this video, we draw an Ethernet cable consisting of two RJ-45 connectors and a CAT-6 cable.
Though Zuken E3 has much of the look and feel of a schematic tool that one would use for PCB schematic design, this tool was constructed to handle both the mechanical and electrical aspects of system level design. One must keep in mind that EDA tools are geared for electrical schematic designs, which are dimensionless by their nature. This is why it is so difficult to make a cable design with any intelligence (i.e., properties, parameters, attributes, etc.) in an EDA tool.
The E3 tool is truly a system engineering tool; cabling is simply one of several core capabilities.
