Get and Set Sunlight Source Property Values Example (VBA)

This example shows how to get and set sunlight properties.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Open a part with a sunlight source.
' 2. Open an Immediate window.
'
' Postconditions: Inspect the Immediate window for the sunlight properties.
