AutoCAD Beginner Course | Circle Command Explained AutoCAD Tutorial
In this AutoCAD 2027 tutorial for beginners, you’ll learn how to use the Circle Command to draw accurate circles using a center point, radius, and diameter.
This lesson explains how to start the Circle Command, draw circles with exact measurements, understand radius vs diameter, use the Diameter option, and avoid common beginner mistakes.
Welcome back to Cadelyx — AutoCAD 2027 Made Simple.
In the previous video, we learned about the Polyline Command in AutoCAD 2027 and how it creates connected line segments as one single object. In this lesson, we move to another important basic drawing command: the Circle Command.
The Circle Command is used whenever you need to create circular shapes in AutoCAD. You may use circles for holes in mechanical parts, round columns in architectural drawings, furniture layouts, symbols, center marks, or any object that has a round shape.
In this beginner-friendly AutoCAD tutorial, you will learn how to draw a circle using a center point and radius, how to draw a circle using diameter, and why it is important to understand the difference between radius and diameter before entering values in AutoCAD.
In this video, you will learn:
What the AutoCAD Circle Command is
How to start Circle from the Home tab and Draw panel
How to start Circle by typing C and pressing Enter
How to draw a circle using a center point
How to draw a circle with exact radius
How to draw a circle with exact diameter
The difference between radius and diameter
How to use the Diameter option by typing D
What Center Radius and Center Diameter mean
Why accuracy matters when drawing circles
Common beginner mistakes with radius and diameter
How to practice circles with exact measurements
This video is perfect for complete beginners who are learning AutoCAD 2027 step by step. If you want to create floor plans, mechanical drawings, civil drawings, architectural layouts, interior design drawings, construction drawings, or professional 2D drafting projects, the Circle Command is one of the basic tools you need to understand.
The most important lesson from this video is simple: always check whether AutoCAD is asking for radius or diameter. If AutoCAD asks for radius and you enter the full diameter value by mistake, your circle will become larger than expected.
AutoCAD is not about drawing shapes by guessing. AutoCAD is about drawing with accurate measurements. So when you know the radius or diameter, type the exact value instead of clicking randomly.
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 Arc Command. An arc is like a part of a circle, and it is useful when we need curved shapes instead of a full circle.
