Understanding the Importance of Purging in AutoCAD
Purging in AutoCAD is essential for maintaining clean and efficient drawings. It helps eliminate unnecessary elements such as unused block definitions, styles, layers, and other named objects that may otherwise bloat your file size. By regularly purging your drawing, you can enhance performance, streamline workflows, and reduce the chances of encountering errors.
