This diagram was generated from a standard cable schedule. Click any cable to view its metadata, drag devices to rearrange the layout, or pan and zoom to explore the topology.
This is exactly what you'll get when you upload your cable schedule
It's hard to validate topology in a spreadsheet. Managing thousands of cable rows without visualization creates a "blind spot" where design errors hide—until they surface as change orders, rework, or schedule delays.
