AutoCAD Beginner Course | Trim Command Explained AutoCAD Tutorial
In this AutoCAD 2027 tutorial for beginners, you’ll learn how to use the Trim Command to cut and remove extra parts of objects accurately.
This lesson explains cutting edges, basic Trim workflow, Trim vs Delete, trimming lines, circles and arcs, intersections, wall cleanup, and common beginner mistakes in AutoCAD.
Welcome back to Cadelyx — AutoCAD 2027 Made Simple.
In the previous video, we learned the Scale Command in AutoCAD 2027 and understood how to make objects bigger or smaller using a base point and scale factor. In this lesson, we will learn one of the most useful editing commands in AutoCAD: the Trim Command.
The Trim Command is used to cut or remove extra portions of objects. If a line goes beyond a wall, a circle crosses another shape, or a construction line is longer than needed, Trim helps remove the unwanted part without deleting the whole object.
In this beginner-friendly AutoCAD tutorial, you will learn how to start the Trim Command from the Ribbon, how to start it by typing TR, how cutting edges work, and how to trim unwanted parts from lines, circles, arcs, polylines, and wall intersections.
In this video, you will learn:
What the AutoCAD Trim Command is
Where Trim is used in real drawings
How to start Trim from the Home tab and Modify panel
How to start Trim by typing TR and pressing Enter
What a cutting edge means in AutoCAD
Basic Trim workflow for beginners
How to trim extra line parts
Why Trim is different from Delete
How to trim lines, circles, arcs, and polylines
Why Trim needs objects to intersect or touch
How Trim is used to clean wall intersections
Common beginner mistakes with Trim Command
How to practice Trim with simple lines and rectangles
This video is perfect for complete beginners who are learning AutoCAD 2027 step by step. If you want to create floor plans, architectural drawings, mechanical drawings, civil drawings, interior layouts, construction drawings, wall layouts, door openings, or professional 2D drafting projects, the Trim Command is one of the most important modify tools to understand.
The most important beginner lesson from this video is simple: Trim removes only the part you click, while Delete removes the full object. If you want to clean extra geometry without removing the entire object, use Trim.
You will also learn why intersections matter. Trim works best when objects touch or cross each other. If Trim is not working, zoom in and check if the objects are actually intersecting.
This video is part of the complete AutoCAD 2027 Full Course for Beginners on Cadelyx. The goal of this course is to make AutoCAD simple, practical, and easy to understand for students, engineers, architects, interior designers, civil drafting learners, mechanical drafting learners, construction professionals, freelancers, and anyone who wants to learn AutoCAD from zero.
In the next video, we will learn the Extend Command. Extend is almost the opposite of Trim. Trim cuts extra parts, while Extend makes objects longer until they reach a boundary.
