Systems and sheets
Devices and ports
A node is a drawing occurrence of a physical device. Ports represent the device's connection points. Repeated occurrences can share physical-device metadata.
Connections and cables
Edges connect ports. Their routed paths explain how the system fits together, while cable labels identify the physical connection. Flags let a connection continue elsewhere without drawing a long continuous route.
Sheets
Use sheets to organize the infinite canvas into deliverable pages. Sheet names describe the drawing; device and cable labels describe the system.
Reusable drawings
Blueprints capture reusable groups of equipment and connections. Keep recurring assemblies consistent rather than redrawing them from scratch.
