These fields relate to the focus area. All fields can receive user input, which will alter the location of the focus point.
Focus Point If you have any Spotlight focus points, they will appear in this drop-down. BeamViz will adjust the focus point to that location and face plane height. It will also auto-populate the ‘focus area’ field with the point’s name.
Face Plane sets the height of your instrument’s focus and is the main cut plane for BeamViz objects. Under Focus Area you can also specify an additional cut plane at any height (even negative) and select an option to show the beam at floor level.
Angle to face is the angle from the face to the light. Straight top light is 90°. Changing this value will adjust the beam based on the Fixed Parameters setting.
Throw is the distance from the light to your focus point. Changing this value will adjust the beam based on the Fixed Parameters setting.
Throw △ X and △Y is the plan distance between the light and focus point.
The Pan/Tilt sliders will focus the light relative to the beam object’s rotation (top of the OIP).
