   Symbols have their own Symbols panel (the Symbols button in the editor; in the full catalog they're under the Symbols tab). It has about 70 built-in symbols, sorted into US, Europe and Shared packs (All shows every pack): US (27): outlets — Single, Duplex, Quad, GFCI, 240V, 20A, Tamper-Resistant, Isolated Ground, AFCI, Range, Dryer, Weatherproof, Switched, USB and Floor Outlet; switches — Single, Double, 3-Way, 4-Way, Dimmer, Smart, Pilot Light, Key, Timer, Occupancy Sensor, Weatherproof and Low Voltage. Europe (14): sockets — Earthed, Unearthed, Double, Triple, Switched, Outdoor IP44, USB and 400V 3-Phase; switches — One-Way, 2-Gang, Two-Way, Intermediate, Dimmer (EU) and Push Button. Shared (28): lights (Ceiling, Recessed, Wall, Pendant, Track, Under-Cabinet), Ceiling Fan, Electrical Panel, Smoke, CO and Smoke/CO Detectors, Doorbell, Motion Sensor, Junction Box; plumbing — Shut-off Valve, Floor Drain, Hose Bib, Water Heater; HVAC — Thermostat, Supply Vent, Return Vent; telecom — Phone Jack, Data Jack, Wi-Fi Access Point; CCTV Camera; and North Arrow, Marker Dot and Callout Circle. Each outlet and switch type draws its own standard plan symbol (a GFCI outlet is tagged GFCI, a dimmer S with a D, and so on). Circuit line in the Symbols panel joins switches, outlets and lights into a circuit (see circuit lines), and the Electrical plan export adds a Symbol legend listing each type used, with a count, plus a Circuits list — see electrical plan outlets switches symbols. Anything else from the general reference above can be added with Upload custom symbol (a transparent PNG kept in your library for every plan — see upload custom symbols). Symbols appear on the 2D plan and in every export and print; free-standing symbols such as lights and vents do not appear in the 3D view.
