AWR creates and maintains many generic 3D parts for customers to use. The primary method of customers accessing these parts are from the AWR website. AWR may need to update 3D parts as issues are discovered and fixed. This script is used to check whether there is a newer version available on the website for any of the downloaded 3D parts used in a project. See 3D Parts Update in the AWRDE documentation for more details on using this script.
