Understanding AutoCAD Viewports

Viewports in AutoCAD serve as windows that allow you to view different parts of your model or drawings at various scales. Mastering how to convert and manipulate these viewports can significantly enhance your workflow. Here is a comprehensive guide on how to convert viewports in AutoCAD 2025.

Steps to Change a Viewport in AutoCAD
