What Is the Difference Between Zoom All and Zoom Extents in AutoCAD?

AutoCAD is a powerful software used by professionals in various industries for creating precise and detailed drawings. One of the most commonly used features in AutoCAD is the zoom function, which allows users to view their drawings at different scales. In this article, we will explore the difference between two zoom commands – Zoom All and Zoom Extents.

Zoom All

The Zoom All command in AutoCAD is used to fit the entire drawing within the current viewport. It ensures that all objects in the drawing are visible on the screen without any clipping. This command is particularly useful when you want to get an overview of your drawing or when you have zoomed in too far and want to quickly return to the original view.

To use the Zoom All command, simply type ‘ZOOM’ in the command line and press Enter. Then select ‘A’ for All or click on the corresponding icon from the toolbar. Alternatively, you can use the keyboard shortcut ‘Z’ followed by ‘A’.


Let’s say you have a complex architectural floor plan with multiple layers and objects. You are currently working on a specific area of the drawing but want to see how it fits into the overall layout. By using Zoom All, you can quickly zoom out and view the entire floor plan without losing your current position or selected objects.

Zoom Extents

The Zoom Extents command, on the other hand, adjusts the view so that all objects in your drawing are displayed at their maximum size within your current viewport. It automatically calculates and sets an appropriate scale factor based on your drawing’s extents.

To use Zoom Extents, type ‘ZOOM’ in the command line and press Enter. Then select ‘E’ for Extents or click on its corresponding icon from the toolbar. You can also use the keyboard shortcut ‘Z’ followed by ‘E’.

Imagine you are working on a mechanical assembly drawing that contains various components and subassemblies. You have zoomed in on a specific part of the drawing to make detailed modifications. Once you are done, using the Zoom Extents command will automatically adjust your view to include all the components, ensuring that nothing is left out of sight.


In summary, both Zoom All and Zoom Extents are essential commands in AutoCAD that help users navigate and manipulate their drawings effectively. While Zoom All fits the entire drawing within the viewport, Zoom Extents adjusts the view to display all objects at their maximum size. Understanding the differences between these two commands will allow you to optimize your workflow and enhance your productivity when working with AutoCAD.
