How Do I Cut Part of a Drawing in AutoCAD?

Are you looking to cut a specific part of a drawing in AutoCAD? Don’t worry, it’s much easier than you might think! In this tutorial, we will walk you through the steps to cut part of a drawing in AutoCAD using simple commands and techniques.

Step 1: Select the Drawing

To begin, open your AutoCAD software and select the drawing that contains the object or part you want to cut. This can be done by either using the “File” menu or simply double-clicking on the file in your project folder.

Step 2: Use the Trim Command

The Trim command in AutoCAD allows you to remove unwanted portions of lines, arcs, circles, or any other geometric objects. This is exactly what we need to cut out a specific part of our drawing.

Note: Before using the Trim command, make sure that all necessary layers are turned on and unlocked. This will ensure that you can select and modify all objects as needed.

Option 1: Cutting with Boundaries

If your drawing has easily definable boundaries around the part you want to cut, follow these steps:

  1. Select the Trim command from the Modify panel or type “TR” on your keyboard and press Enter. You can also access it from the right-click context menu.
  2. Pick one side of your boundary line as a cutting edge by clicking on it.
  3. Choose which portion of the line(s) or object(s) you want to remove by hovering over them with your cursor.

    You will notice that selected areas are highlighted.

  4. Click on each selected portion to trim them accordingly. The trimmed parts will be removed instantly from your drawing.
  5. Press Enter or right-click to exit the Trim command.

Tip: Holding down the Shift key while selecting multiple objects allows you to trim them all at once. This can be a real time-saver if you have several objects to trim within the same boundary.

Option 2: Cutting with Selection

If your drawing doesn’t have clear boundaries, you can use the Selection method. Here’s how:

  1. Select the Trim command as explained in Option 1.
  2. Type “F” on your keyboard and press Enter to activate the Fence option. This creates a virtual boundary for trimming.
  3. Draw a line across or around the portion you want to remove.

    The line doesn’t have to be exactly on top of the object(s) you want to cut; it only needs to intersect them.

  4. AutoCAD will automatically select all objects that intersect with your fence line. If any unwanted objects are selected, simply click on them again to deselect them.
  5. Press Enter or right-click to execute the Trim command and remove the selected portions from your drawing.

Note: You can also use other selection methods like Window, Crossing, or Polygon instead of Fence if they better suit your needs. Experiment with different options to find what works best for you!

Step 3: Review and Save Your Drawing

After trimming parts of your drawing, take a moment to review it and ensure that everything looks as intended. If you’re satisfied with the result, save your modified drawing by clicking on “File” in the menu bar and selecting “Save” or by using the Ctrl + S keyboard shortcut.

Conclusion:

Trimming or cutting parts of a drawing in AutoCAD is an essential skill for any CAD designer or drafter. By using the Trim command and selecting the appropriate boundaries or selection methods, you can easily remove unwanted portions and create clean, precise drawings.

Remember to practice these techniques regularly to improve your efficiency and accuracy. Happy trimming!
