Signal-flow guide
Good AV schematics make direction, signal domain and device ownership obvious before anyone reads a note.
Route by domain
Start with audio, video, power, control-net, AVoIP, control-io or other. Connector, cable and protocol metadata can narrow compatibility further.
Use tags for distance
Long or cross-room paths do not always need a visible wire. HTIFA supports tagged connections as real selectable schematic edges.
Export for review
The best drawing set is readable by installers, clients and designers through a PDF, BOM CSV or readonly browser snapshot.
