This document provides instructions for updating part files in the Agile system. It outlines searching for existing files by part number, with the goal of having both an Inventor part file and drawing for each part. It describes checking out existing parts from Agile, modifying and creating the required files, and checking them back in along with an ECO for release. It notes that over 250 single part models and drawings and more than a dozen assembly models and drawings were recently updated in this process.
