Draw a plan, divide it into labeled rooms, and set lighting for each room.

Layout

Lock the layout to keep fixture positions fixed while comparing light levels.

Photometric C0 points along +X at 0°, and −Z at 90°. Confirm the fixture file’s axes when comparing layouts.

Offsets measure wall to fixture center; 0 selects automatic half-spacing. Single rows or columns stay centered. Custom rooms show outer-wall offsets; ceiling grids use tile-aligned offsets.
