Redirect Spotlight Example (VBA)

This examples shows how select a spotlight and two sketch points.  The spotlight is then redirected to point along the vector that is defined by the two points.  

NOTE: This example is specific to the model used to develop and test the example. You will need to modify the example to allow for more general conditions.
