* Understanding Traces: * Traces in AutoCAD allow multiple users to collaborate on a drawing by adding comments and updates. * Each Trace keeps a history of contributions and modifications made by different users. * Adding Information to Existing Trace: * When a CAD designer updates a drawing by adding a new hole, this action is recorded in the existing Trace. * The Trace palette will show contributors and modifications, maintaining a detailed record. * Expected Result: * After adding the new hole, the existing Trace will be updated to show another contributor. * This helps in tracking changes and identifying who made specific updates. * Conclusion: * The Traces palette will display another contributor in the existing Trace after the update.
