The Heliodon tool is similar to the Set Sun Position command. Vectorworks places a specific Heliodon object whose parameters can be adjusted in the Object Info palette. This makes it much more flexible than the Set Sun Position command, allowing you to change the time of the day or the day of the year directly from the Object Info palette. As well as this, the Heliodon is connected to a Physical Sky. As you change the time of the day the physical sky will update to reflect that time of the day. For example, if you set the time of the day to be around sunset, the physical sky will change to reflect a dusky sky. If you set the time of the day to be after the sun has gone down, the physical sky will change to show stars rather than clouds.
