AutoCAD | How to Trim and Extend Areas Using a Lasso for Fast, Precise Editing

✂️ Want to speed up your trimming and extending in AutoCAD? Knowing how to trim and extend areas using a lasso selection is a game-changer for editing complex drawings quickly and intuitively.

Introduced in newer versions of AutoCAD, the lasso selection allows you to freely “draw” around objects rather than using traditional window or crossing selections. When trimming or extending, this makes it much faster to select precisely the geometry you want—even in cluttered or detailed drawings.

In this tutorial, you’ll learn how to trim and extend areas using a lasso in AutoCAD, helping you work faster and with more confidence on projects of any size.

🔧 What you’ll learn:
• What lasso selection is and why it’s powerful:
 – Allows you to draw an irregular shape around objects for selection
 – More precise than rectangular window or crossing selections
 – Perfect for dense, complex drawings with overlapping elements
• How to use a lasso with TRIM and EXTEND commands:
 ✅ Start the TRIM or EXTEND command as usual
 ✅ When prompted to select objects, click and hold your left mouse button
 ✅ Drag your cursor to “lasso” around the objects you want to select
• Lasso selection types:
 – Clockwise lasso → window selection (selects objects completely inside)
 – Counterclockwise lasso → crossing selection (selects objects it crosses)
• Tips for effective trimming and extending with a lasso:
 – Zoom in for precise selection around complex areas
 – Keep your lasso path as tight as possible to avoid selecting unwanted objects
 – Combine lasso with object snaps for even more control
• Practical examples:
 – Quickly trimming overlapping lines in a dense floor plan
 – Extending only specific lines in a busy mechanical drawing
 – Cleaning up excess geometry in civil site layouts using a freehand selection

🧠 Why trimming and extending with a lasso matters:
✔ Saves significant time during editing
✔ Improves precision when working in detailed areas
✔ Makes working in complex drawings faster and less frustrating
✔ Essential for professional drafting and modeling in AutoCAD
✔ Adds flexibility and speed to your CAD workflow
