How Do You Draw a Smooth Circle in SketchUp?

Are you struggling to draw a smooth circle in SketchUp? Don’t worry, we’ve got you covered!

In this tutorial, we will walk you through the step-by-step process of creating a perfect circle in SketchUp. So, let’s get started!

Step 1: Select the Circle Tool

To begin, open SketchUp and navigate to the toolbar on the left-hand side of your screen. Locate and select the “Circle” tool icon. You can also use the shortcut “C” on your keyboard to activate the tool.

Step 2: Click and Drag

With the Circle tool activated, click anywhere on your workspace to set the center point of your circle. Then, hold down your mouse button and drag outward to define the radius of your circle. Be sure to drag until you achieve the desired size.


  • Hold Shift: If you want to draw a perfect circle (with equal x and y radii), hold down the Shift key while dragging.
  • Type in Dimensions: Alternatively, you can type in specific dimensions for both x and y radii. Simply click once to set the center point, release your mouse button, and type in your desired dimensions using the format “x,y” (e.g., “10′, “20′”).

Step 3: Create a Smooth Circle

By default, SketchUp creates a segmented circle with multiple straight edges. To make it appear smoother, we need to increase its number of sides.

Follow these steps:

  1. Select Your Circle:
  2. With the Circle tool still active, click on the circle you just created to select it. You will notice that it becomes highlighted with blue edges.

  3. Access Entity Information:
  4. In the “Window” menu at the top of your screen, select “Entity Info.”

    This will open a sidebar with information about your selected circle.

  5. Change Segment Count:
  6. In the Entity Info sidebar, locate the “Segments” field and click on its value. Enter a higher number to increase the number of sides in your circle. For example, entering “36” will create a much smoother appearance.


  • Keep It Balanced: Be cautious when increasing the segment count excessively, as it can impact your computer’s performance and slow down SketchUp.
  • Experiment: Feel free to experiment with different segment counts to find a balance between smoothness and performance that suits your needs.

Congratulations! You have successfully drawn a smooth circle in SketchUp.

Remember, practice makes perfect, so keep experimenting with different tools and techniques to enhance your SketchUp skills. Happy designing!
