How Do You Compare Two Drawings in AutoCAD?

by

Comparing two drawings in AutoCAD can be a daunting task, especially if they are complex and have numerous elements. However, with the right tools and techniques, you can efficiently compare and identify differences between the two drawings. In this tutorial, we will explore different methods to compare two drawings in AutoCAD.

Method 1: Using the “DWG Compare” Tool

The “DWG Compare” tool is a powerful feature in AutoCAD that allows you to compare two drawings and visually identify any changes or differences between them.

  • Step 1: Open both drawings that you want to compare in AutoCAD.
  • Step 2: In the “Manage” tab of the ribbon, click on the “DWG Compare” button.
  • Step 3: A new window will appear with options to specify the original and modified drawings. Select the appropriate files for each option.
  • Step 4: Click on the “Compare” button to start the comparison process.

The “DWG Compare” tool will highlight any differences between the two drawings by using different colors. It will display added entities in green, modified entities in yellow, and deleted entities in red.

Method 2: Visual Comparison

If you prefer a more manual approach, you can visually compare two drawings side by side using AutoCAD’s layout feature. This method is particularly useful when comparing small sections of a drawing or when you want more control over the comparison process.

  • Step 2: In the “View” tab of the ribbon, click on the “Viewports” button and select “2 Viewports Vertical” or “2 Viewports Horizontal” depending on your preference.
  • Step 3: Arrange the two drawings in each viewport.
  • Step 4: Zoom and pan as necessary to align corresponding elements in both drawings.

    • By visually comparing the two drawings side by side, you can easily identify any differences or modifications. This method gives you more flexibility and control over the comparison process but may take longer for complex drawings.

    Method 3: Using External Comparison Software

    If the built-in comparison tools in AutoCAD do not meet your requirements, you can also use external comparison software specifically designed for CAD files. These software solutions offer advanced features and functionalities for comparing drawings in AutoCAD.

    Note: External comparison software may come at an additional cost and require installation and setup.

    In Conclusion

    Comparing two drawings in AutoCAD is an essential task when reviewing changes or modifications. Whether you choose to use the built-in “DWG Compare” tool, visually compare side by side, or opt for external comparison software, it’s crucial to have a systematic approach to ensure accuracy.

    In this tutorial, we explored different methods to compare two drawings in AutoCAD. Remember that each method has its advantages, so choose the one that suits your needs best. With practice and experience, you will become proficient in identifying differences between drawings efficiently.

    Now it’s time to put your skills into practice!
