What Is SDI in AutoCAD?

AutoCAD is a powerful software used by engineers, architects, and designers to create precise 2D and 3D drawings. It offers a wide range of features and functionalities to enhance the workflow and productivity of its users.

Understanding SDI

SDI stands for Single Document Interface. In simple terms, it refers to the number of drawing files that can be opened simultaneously in AutoCAD. The SDI setting determines whether AutoCAD opens multiple drawings in separate windows or within a single window.

By default, AutoCAD uses an SDI value of 1, which means that each drawing is opened in a separate instance of the software. This can be useful when working on multiple projects or collaborating with others who may have different preferences.

Changing the SDI Setting

To change the SDI setting in AutoCAD, follow these steps:

  1. Open the Options Dialog Box: Click on the “Application” button located at the top-left corner of the AutoCAD window. From the dropdown menu, select “Options. “
  2. Navigate to Display: In the Options dialog box, click on the “Display” tab located on the left-hand side.
  3. Adjust SDI Value: Under the “Window Elements” section, you will find an option labeled “SDI.”

    Use the dropdown menu next to it to select your desired value. Choosing a value of 0 will open multiple drawings in a single window, while choosing a value greater than 1 will open each drawing in a separate window.

  4. Apply Changes: Once you have selected your preferred SDI value, click on the “Apply” button to save the changes. You can also click on “OK” to close the Options dialog box.

It’s important to note that changing the SDI setting requires restarting AutoCAD for the changes to take effect.

Benefits of Using SDI

The choice between using a single document interface or multiple document interfaces depends on personal preferences and workflow requirements. However, there are certain benefits to using SDI in AutoCAD:

  • Improved Organization: Opening multiple drawings in separate windows allows for better organization and easier navigation between different projects.
  • Better Multitasking: With SDI enabled, you can work on one drawing while referencing or comparing another drawing without constantly switching between windows.
  • Enhanced Collaboration: When collaborating with others, it may be beneficial to have each drawing open in a separate window, allowing multiple users to work simultaneously without interfering with each other’s progress.

In Conclusion

The SDI setting in AutoCAD determines whether drawings are opened in a single window or separate windows. By adjusting this setting, users can customize their workspace based on personal preferences and workflow requirements. Whether you choose to use a single document interface or multiple document interfaces, AutoCAD offers flexibility and efficiency for all your design needs.
