Then calibrate the scale with K, drop cameras with C, and trace the walls with W so the coverage knows what it can't see through.
Then calibrate the scale with K, trace the walls with W or B, and place detectors, call points and sounders with C — or tap each room with auto-place (A).
You drew a line 0 px long. What is that on the ground?
A plain number is millimetres · or type a unit: 4.5 m, 450 cm, 4500 mm
Handy references: a UK parking bay is 4,800 × 2,400 mm, a single carriageway lane 3,650 mm, a standard door leaf 900 mm (a doorway about 926 mm), a shipping container 6,058 or 12,192 mm long.
What are you designing? The tools, the library, the checks and every output — PDF, proposal, schedules, link and email — follow the type you pick.
Starting a new design clears the one that is open — save it first if you need it.
You can switch a drawing between CCTV and fire alarm later with the switch in the top bar; anything of the other kind is kept, hidden, until you switch back.
