How Do You Chamfer Edges in Sketchup?

Chamfering edges in Sketchup is a useful technique that allows you to create beveled corners and smooth transitions between different surfaces. Whether you’re working on architectural models or 3D designs, chamfering can add a touch of realism and refinement to your creations.

Step 1: Select the Edges

To begin chamfering edges in Sketchup, you need to select the specific edges you want to modify. Simply click on the Edge Select tool in the toolbar or press the keyboard shortcut ‘E’.

Note: You can select multiple edges at once by holding down the Shift key while clicking on each edge.

Step 2: Access the Chamfer Tool

Once you have selected the desired edges, go to the ‘Extensions’ menu at the top of your Sketchup window. From there, navigate to ‘Fredo6’ and choose ‘RoundCorner’.


  • If you don’t have the RoundCorner extension installed, you will need to download and install it first. You can find it easily by searching for “Sketchup RoundCorner extension” online.

Step 3: Adjust Chamfer Parameters

With RoundCorner activated, a dialog box will appear that allows you to adjust various parameters for your chamfer. These parameters include:

  • Distance: Determines how far inward or outward the chamfer extends from each selected edge.
  • Segments: Controls the number of segments used to create a smooth transition along each chamfered edge.
  • Select Profiles: Enables you to choose which edges should be chamfered.

Experiment with these settings to achieve the desired chamfer effect. Don’t forget to preview your changes using the ‘Preview’ button before applying them.

Step 4: Apply the Chamfer

Once you are satisfied with the chamfer settings, click on the ‘Apply’ button to make the changes permanent. Sketchup will then calculate and apply the chamfers to your selected edges.

Step 5: Fine-tune and Refine

If you’re not completely happy with the results, don’t worry! You can always go back and adjust the chamfer parameters until you achieve the desired outcome. Simply repeat steps 3 and 4 as necessary.

TIP: Remember that chamfering is a non-destructive operation, meaning you can always revert back to your original edges without losing any geometry.

In Conclusion

Chamfering edges in Sketchup is a straightforward process that adds depth and realism to your 3D models. By following these steps and experimenting with different settings, you can create visually appealing designs with smooth transitions between surfaces. So go ahead, give it a try, and take your Sketchup skills to the next level!
