How Do You Extend in AutoCAD?

by

AutoCAD is a powerful software widely used by professionals in industries such as architecture, engineering, and construction. One of the essential skills to master in AutoCAD is extending lines, arcs, and other objects. In this tutorial, we will explore different methods to extend in AutoCAD effectively.

Extending Lines

Extending lines allows you to lengthen them to meet other objects or boundaries. To extend a line in AutoCAD, follow these steps:

  1. Select the Extend command from the Modify panel in the Ribbon, or type “EX” in the command line.
  2. Select the line you want to extend by clicking on one of its endpoints.
  3. Select the boundary object that you want to extend the line to by clicking on it.
  4. If you want to extend multiple lines at once, press and hold the “Shift” key while selecting additional lines and then select the boundary object.
  5. Press “Enter” or right-click and select “Enter” to complete the extension.

You can also use a crossing selection to extend multiple lines simultaneously. To do this:

  1. Select the Crossing Selection tool from the toolbar or type “CROSSINGSELECTION” in the command line.
  2. Create a crossing selection box that includes both the lines you want to extend and their boundary objects.
  3. Type “All” and press “Enter” when asked which objects should be extended.

Extending Arcs and Circles

To extend arcs and circles in AutoCAD, the process is quite similar to extending lines:

  1. Select the Extend command from the Modify panel in the Ribbon, or type “EX” in the command line.
  2. Select the arc or circle you want to extend by clicking on it.
  3. Select the boundary object that you want to extend the arc or circle to by clicking on it.
  4. If you want to extend multiple arcs or circles at once, press and hold the “Shift” key while selecting additional objects and then select the boundary object.

Tips for Effective Extending:

  • Avoid Overextending:

    When extending objects, make sure not to overextend them beyond their intended boundaries. It’s essential to maintain accuracy in your drawings.
  • The Fence Option:

    AutoCAD provides a useful option called “Fence“. Instead of selecting individual objects, you can draw a polyline as a fence around multiple objects that need extending.

    This allows for quick and efficient extensions.

  • The Trim-Extend Command:

    If you frequently use both trimming and extending functions, AutoCAD offers a convenient command called “TRIM–EXTEND“. This command combines the functionality of both commands in one operation, saving you time and effort.

With these methods and tips, you can extend lines, arcs, and circles accurately in AutoCAD. Practice using different techniques to become proficient in extending objects and enhance your drafting skills.
