How Do I Extend Two Lines in AutoCAD?

by

In AutoCAD, extending two lines can be a useful feature when you want to connect or join two line segments together. This functionality allows you to extend the lines beyond their original endpoints, creating a seamless connection between them.

Using the Extend Command

The extend command in AutoCAD is a powerful tool that lets you extend one or more line segments to meet another object. To extend two lines, follow these steps:

  1. Select the “Extend” command from the Modify toolbar or type “EX” on the command line and press Enter.
  2. When prompted to select objects, click on the first line segment you want to extend.
  3. Next, click on the second line segment you want to extend. AutoCAD will automatically detect and highlight both lines.
  4. Press Enter to complete the selection.
  5. Now, specify a boundary or object that will act as a boundary for extending the lines. This can be another line, polyline, or even an arc.
    • Note: Make sure that the boundary extends past both of the lines you want to extend.
  6. AutoCAD will now extend both lines until they meet at the boundary object.

The Extend command also works with other objects such as polylines, arcs, circles, and even splines. It provides flexibility and precision when extending multiple objects simultaneously.

Tips for Extending Lines

To ensure accurate results when extending two lines in AutoCAD, keep these tips in mind:

  • Selecting Objects: When selecting lines or other objects for extension, make sure you choose them in the correct order. The first object will be extended to meet the second object.
  • Boundary Objects: Use boundary objects that extend beyond the original endpoints of the lines you want to extend.

    This ensures that the lines are extended to their intended endpoints.

  • Trimming First: If your lines have unwanted segments beyond their desired endpoints, it’s a good practice to trim them before using the extend command. This helps in avoiding incorrect extension results.
  • Using Object Snaps: AutoCAD provides various object snaps that can help you precisely select and specify boundary objects. Experiment with different object snaps like Endpoint, Intersection, or Node to achieve accurate results.

In Conclusion

The ability to extend two lines in AutoCAD is a valuable feature that allows you to create seamless connections between line segments. By using the Extend command and following some best practices, you can extend lines accurately and efficiently in your CAD drawings.

Remember to practice and experiment with different scenarios to gain familiarity with this useful command. With time and experience, extending lines in AutoCAD will become second nature!
