To Create a Target Point Light From a Point Light

1. At the command prompt, enter lightingunits and set the value to 1 (American units) or 2 (International SI units) for photometric lighting.
2. Click Modeling tab > Render panel > Light drop-down > New Point Light.
3. Click in the drawing to specify a location for the light.
4. At the Command prompt, enter n and enter a name. This name will appear in the properties and in the Lights in Model window.

   You can continue to specify properties by entering options, or you can exit and set properties interactively. When you use the interactive method, you can see the results of your changes as you work.

5. Press Enter twice to exit the command.
6. Select the light. In the Lighting Properties tab in the Properties Inspector, change the Targeted property to Yes.

   Additional target properties become available: Target X, Target Y, and Target Z.

   Note:

   When changing a point light to target light, the name of the light remains the same. If it still says point light, you might want to change the name to target light.
