Aiming a Spotlight

In a building model, you can control the position of a spotlight to achieve the desired lighting effects. To position a spotlight, use its angle parameters and the Rotate tool.

To aim a spotlight

1. Add spotlights to the building model, placing them in their approximate locations.

   See Adding a Lighting Fixture to a Building Model.

2. Set up views, as follows:
   1. Leave open (or re-open) the view in which you added the lighting fixtures. (For this procedure, this view is referred to as the placement view.) Zoom in on the fixtures, so you can easily select them for rotating or repositioning. Turn on the display of light sources. (See Displaying Light Sources in a View.)
   2. Click View tabWindows panel (Close Hidden) to close all other project views.
   3. Open a second view in which you will be able to see the light cast on surfaces (such as an elevation view, section view, or 3D view). (For this procedure, this view is referred to as the lighting view.) On the View Control Bar, for Visual Style, select Shaded. Turn on the display of light sources. (See Displaying Light Sources in a View.)

   4. To tile the windows, so you can see both views at the same time, click View tabWindows panel (Tile).
3. In the placement view, rotate the spotlights to aim their light in the desired direction.

   Use the Rotate tool. See Rotating Elements.

4. To tilt a spotlight and control the size of its beam, do the following:
   1. In either view, select a spotlight, and click Modify | Lighting Fixtures tabProperties panel (Type Properties).
   2. Click Duplicate to create a new type.
   3. Enter a name for the type, and click OK.
   4. In the Type Properties dialog, scroll down to locate the Tilt Angle, Spot Field Angle, and Spot Beam Angle parameters.
   5. Enter the desired values for each parameter.

      See Angles for Spotlights.

   6. Click OK.
   7. Check the results in the lighting view.

      For example, in the following image, the left spotlight has a smaller beam angle and field angle. For the right spotlight, the tilt angle was changed from 60 degrees to 45 degrees.

      

   Repeat this step for each spotlight that needs to be tilted.

5. If necessary, make adjustments to achieve the desired result.

   For example, you may need to add or remove spotlights, adjust their positions, and change their rotation angles and tilt, field, and beam angles to obtain the desired lighting effects.

   Tip: To evenly illuminate a surface, position the lighting fixtures so the beam angles overlap each other slightly.
