How Do You Merge Objects in AutoCAD?

by

Merging objects in AutoCAD is a fundamental skill that every user should master. Whether you’re working on a complex engineering project or a simple floor plan, being able to merge objects can greatly streamline your workflow and enhance the overall efficiency of your design process.

What Does it Mean to Merge Objects?

Merging objects refers to the process of combining two or more separate entities into a single object. This can be particularly useful when you want to create a cohesive design or perform specific operations on multiple objects simultaneously.

Why Merge Objects?

There are several reasons why you might need to merge objects in AutoCAD:

  • Organize Your Design: Merging similar objects allows you to keep your drawings clean and organized. Instead of having multiple separate entities, merging them creates a unified structure.
  • Edit Objects Efficiently: By merging objects, you can edit them collectively rather than individually. This saves time and effort, especially when making changes to complex designs.
  • Perform Operations: Merged objects enable you to perform various operations such as trimming, extending, or modifying properties on multiple entities at once.

Methods for Merging Objects in AutoCAD

In AutoCAD, there are different methods available for merging objects based on your specific requirements. Let’s explore some common techniques:

Method 1: Union Command

The Union command combines selected objects into a single entity by removing any overlapping areas and creating a new boundary around the merged shape. Here’s how you can use the Union command:

  1. Select all the objects that you want to merge using the “Select” tool from the toolbar or by typing “S” on the keyboard.
  2. Once the objects are selected, type “UNION” in the command line and press Enter.
  3. AutoCAD will prompt you to select a base object. Choose one of the objects as the base by clicking on it.
  4. Finally, press Enter to complete the merge.

Note: The Union command merges objects into a single closed boundary. If you want to merge open entities or maintain individual boundaries, consider using other methods.

Method 2: Join Command

The Join command connects separate lines, arcs, or polylines into a continuous object. It is particularly useful when working with open entities that need to be merged without removing segments. Follow these steps to use the Join command:

  1. Select all the objects you want to merge using the “Select” tool or by typing “S”.
  2. Type “JOIN” in the command line and press Enter.
  3. AutoCAD will prompt you to select an object. Click on any segment of one of the objects you want to join.
  4. The selected objects will be joined together, preserving their individual boundaries.

Note: The Join command only works with lines, arcs, and polylines. It does not merge other types of objects such as circles or ellipses.

Method 3: Pedit Command

The Pedit (Polyline Edit) command is useful for merging multiple lines or arcs into a single polyline object. Here’s how you can use it:

  1. Select all the lines or arcs you want to merge.
  2. Type “PEDIT” in the command line and press Enter. Click on one of the lines or arcs.
  3. The selected lines or arcs will be merged into a single polyline object.

Note: The Pedit command works only with lines and arcs, not with other types of objects like circles or ellipses.

In Conclusion

Merging objects in AutoCAD is a powerful technique that can greatly enhance your design workflow. Whether you need to organize your drawings, edit objects efficiently, or perform operations on multiple entities, knowing how to merge objects is essential. By using commands like Union, Join, and Pedit, you’ll be able to create cohesive designs and work more effectively in AutoCAD.
