Dependency Analysis

Find required files, perform impact analysis

Projects help you to organize large modeling projects by finding required files, managing and sharing files and settings, and interacting with source control. See What Are Projects? and watch Using Projects to Collaborate, Track, and Merge Changes and Perform Code Reviews (4 min, 50 sec).
