How to Use the Offset Command in AutoCAD: A Beginner’s Guide

The Offset command in AutoCAD is one of the simplest and most useful tools for creating parallel lines, concentric circles, or duplicating objects at a specified distance. Whether you’re working on floor plans, mechanical parts, or diagrams, the Offset command can save you time and effort. Here’s a simple guide to help you master it.

What Does the Offset Command Do?

The Offset command creates a copy of an object (like a line, circle, or arc) at a set distance away from the original. This new object can be placed inside or outside the original, depending on your input.

Step-by-Step: How to Use the Offset Command

1. Start the Offset Command

Type OFFSET in the command line and press Enter.
Alternatively, click the Offset tool in the Modify panel on the ribbon.

2. Set the Offset Distance

AutoCAD will prompt you to specify the distance for the offset.
Type the desired distance (e.g., 5) and press Enter.

3. Select the Object to Offset

Click on the object you want to offset. This can be a line, polyline, circle, arc, or other supported object.

4. Specify the Offset Side

Move your cursor to the side where you want the new object to appear.
Click once to place the offset object.

Practical Examples of the Offset Command

Creating Walls in Floor Plans
- Offset a line representing the wall centerline to create inner and outer wall boundaries.
Adding Clearance Around an Object
- Offset a circle to show safety zones or clearance areas.
Designing Patterns
- Use offset to create concentric circles or repeating shapes in mechanical or decorative designs.

Quick Tips for Using Offset

Multiple Offsets: After placing the first offset object, the command stays active, letting you repeat the process without restarting.
Erase Source Object: If you only need the offset object, you can manually delete the original afterward.
Shortcut Key: Type O and press Enter to quickly start the Offset command.

Why Use the Offset Command?

The Offset command streamlines repetitive tasks, ensures precision, and keeps your designs consistent. Once you get the hang of it, you’ll find yourself using it in nearly every drawing you create.

By mastering the Offset command, you’ll add an essential tool to your AutoCAD skillset and simplify many drafting tasks.
