Extrim is a powerful command in AutoCAD that helps you trim and extend objects easily. Whether you are working on a simple drawing or a complex design, knowing how to use Extrim can greatly improve your efficiency and productivity. In this tutorial, we will explore the various features of Extrim and learn how to use it effectively.
What is Extrim?
Extrim is a command in AutoCAD that allows you to trim or extend objects by selecting the boundary edges. The command works by removing the portions of the selected object that lie outside the boundary edges or extending the object to meet the boundary edges. It is particularly useful when you need to quickly modify objects without manually trimming or extending them.
How to Access Extrim?
To access the Extrim command, you can either type “EXTRIM” in the command line or select it from the Modify panel in the Home tab of AutoCAD’s ribbon interface.
Using Extrim
Once you have accessed the Extrim command, follow these steps to effectively use it:
Selecting Objects
The first step in using Extrim is selecting the objects that you want to trim or extend. You can select multiple objects by clicking on them individually or by using selection methods like Window or Crossing.
Selecting Boundaries
After selecting the objects, AutoCAD prompts you to select one or more boundaries for trimming or extending. Boundaries are used as reference edges for trimming or extending objects. You can select boundaries by clicking on them individually.
- Note: The order in which you select boundaries determines which side of an object gets trimmed.
- TIP: To remove a boundary after selection, press and hold down the Shift key while clicking on it.
Trimming or Extending Objects
Once you have selected the objects and boundaries, AutoCAD performs the trimming or extending operation. The portions of the objects that lie outside the boundaries are removed, and the objects are trimmed. If you selected boundaries to extend objects, AutoCAD extends them to meet the boundaries.
- Note: If there are overlapping boundaries, AutoCAD trims or extends objects based on their priority and proximity to each boundary.
Additional Options
The Extrim command also provides additional options that can enhance your trimming and extending experience:
- Fence: Allows you to select multiple boundaries using a freehand selection.
- Project: Projects the selected object onto a plane before trimming or extending it.
- Erase: Erases any remaining geometry after trimming or extending an object.
- Polygonal: Trims or extends objects using a polygonal boundary.
In Conclusion
Using the Extrim command in AutoCAD can significantly speed up your workflow when it comes to trimming or extending objects. By selecting the appropriate boundaries and utilizing its additional options, you can efficiently modify your drawings without manual edits. So next time you find yourself needing to trim or extend objects in AutoCAD, remember to unleash the power of Extrim!
