2. Purge Registered Applications: Enable the purge registered applications option to remove unused objects associated with third-party applications or custom components, optimizing drawing performance and compatibility.
3. Purge Unused Layers with LayDel: Utilize the LayDel (Layer Delete) command to purge unused layers along with their associated objects, providing a comprehensive solution for layer cleanup and optimization.

Best Practices:

To achieve optimal results when using the PURGE command in AutoCAD, it’s essential to adhere to the following best practices:

1. Regular Maintenance: Incorporate purging into your regular drawing maintenance routine to prevent accumulation of unused objects and ensure drawing file efficiency.
2. Review and Preview: Before purging, carefully review the list of unused objects and preview the impact of the purging operation to avoid unintentional deletion of critical elements.
3. Backup and Versioning: Always create backup copies of drawing files before purging to safeguard against data loss or unintended changes, and maintain version control for traceability and accountability.
4. Document Changes: Document and communicate changes made through the purging process to collaborators or stakeholders to ensure transparency and avoid misunderstandings.
