Putting fixtures on truss and stands

Step by step

1. Grab a fixture in the 3D view and drag it onto a truss, T-bar, tripod, totem, booth or column speaker. A green frame and “Snaps onto: …” show where it will land.

2. Or drag it from the fixture list onto an object in 3D. This also works with several selected fixtures or a whole group (grab the group row).
   • On short bars (T-bar, booth), the visualizer then spaces all fixtures evenly.
   • On a truss, new fixtures go into the biggest gap.
3. It's easier to keep track with “by location” above the fixture list. Every holder then gets its own group with its fixtures, and free-standing fixtures are under “No mount (floor/wall)”. To move a fixture to another holder, drag it onto that holder's row. An empty holder shows “Empty – drag fixtures here”. “Object” in the group row selects the holder itself.
4. Click the fixture and set things on the right under “Placement”:
   • “Mounted on”: pick another object or “free on the floor”.
   • On a truss, “Mount”: “hanging” or “standing”, plus “Position” along the bar. Moving heads can also be mounted “sideways” anywhere. On a stand pair, set “Position” fully left or right and adjust “Height on the tube”. The head then clamps to the stand tube and faces the audience.
   • For uplights, bars and lasers, “Aim”: “automatic”, “up”, “forward” or “down”.
   • “Mounting angle”: tip the fixture to any angle (see Tipping fixtures and the test beam).
   • “Rotation” with the slider or buttons.
5. Type exact values under “Position from booth center”, in meters and as seen from the audience:
   • “Sideways”: minus = left, plus = right.
   • “Forward”: plus = toward the audience, minus = toward the back wall.
   • “Height above hall floor”: only for free-standing fixtures, e.g. for a fixture up on a balcony.
6. “Take off object” puts the fixture on the floor in front of the holder. “Place automatically” discards your placement, and the visualizer places the fixture itself again.
