The light beams do not have to be drawn for calculations to be made.

2. Click the Photometer tool from the Spotlight tool set.

3. Click to place the photometer in the drawing, and click again to set the object’s rotation. If this is the first time the object is placed in the drawing, an object properties dialog box opens.

4. Specify the object properties and click OK.

After placing the photometer, set the its Z value on the Object Info palette; illumination values vary depending on the photometer’s elevation.
