How Do I Change Units to Mm in AutoCAD?

by

AutoCAD is a powerful software used extensively in the field of design and engineering. One common task that users often need to perform is changing the units from the default setting to millimeters (mm). In this tutorial, we will guide you through the process of changing units to mm in AutoCAD.

Step 1: Open AutoCAD and Create a New Drawing

To begin, open AutoCAD on your computer and create a new drawing by selecting “New” from the “File” menu or by using the keyboard shortcut Ctrl + N.

Step 2: Accessing Drawing Units

Once you have created a new drawing, navigate to the “Format” tab located at the top of the AutoCAD window. Under this tab, you will find a section called “Drawing Setup,” which contains various options including “Units.” Click on “Units” to proceed.

Note:

If you are using an older version of AutoCAD, you may need to access drawing units through different menus or options. However, the overall process remains similar.

Step 3: Changing Units to Millimeters

In the “Units” dialog box that appears, you will see several options related to unit settings. To change units to millimeters, follow these steps:

  • Select “Millimeters” from the “Insertion Scale” drop-down menu:

    • The insertion scale determines how objects are scaled when inserted into your drawing. By selecting millimeters as the insertion scale, all objects will be automatically scaled accordingly.

  • Select “Millimeters” from the “Length Type” drop-down menu:

    • The length type determines how distances are displayed in your drawing. By selecting millimeters, all measurements will be displayed in millimeters.

  • Click on the “OK” button to apply the changes:

    • Once you have made the necessary selections, click on the “OK” button to apply the unit changes to your drawing.

Step 4: Verify Unit Changes

To ensure that the unit changes have been successfully applied, you can verify them by using the “Distance” command. Simply type “DIST” in the command line and specify two points. The distance between those points will be displayed in millimeters if the unit changes were successful.

Note:

If you have existing objects or drawings that were created using a different unit setting, they will not automatically convert to millimeters. You may need to manually scale or adjust those objects accordingly.

Changing units to millimeters in AutoCAD is a straightforward process that allows you to work with precision and accuracy. By following these steps, you can ensure that your drawings are accurately scaled and measurements are displayed in millimeters.

Remember, AutoCAD offers a wide range of customization options, and understanding how to change units is just one of many useful features that can enhance your workflow.

So go ahead and start exploring AutoCAD’s vast capabilities with confidence!
