How to Create an Object by Symmetry or Mirror with SketchUp?

Creating objects by symmetry or mirror imaging is a common technique used in 3D modeling to achieve balanced and uniform designs. In SketchUp, this process can be easily accomplished using the “Scale” and “Flip Along” tools. If you’re looking to master the art of symmetry in SketchUp, here’s a step-by-step guide to help you create objects with perfect symmetry:

Step 1: Design Your Object

Begin by designing the object you want to create using SketchUp’s modeling tools. Whether it’s a simple shape or a complex structure, ensure that your initial design is positioned correctly within the SketchUp workspace.

Step 2: Select the Object

Once your object is designed, use the “Select” tool to click on the object and ensure that it is highlighted or selected within the workspace. This will indicate that the object is ready for manipulation.

Step 3: Access the Scale Tool

With the object selected, navigate to the “Tools” menu at the top of the SketchUp interface. From the dropdown menu, select “Scale” to activate the Scale tool. Alternatively, you can use the keyboard shortcut “S” to quickly access the Scale tool.

Step 4: Activate Symmetry Mode

With the Scale tool activated, move your cursor towards one of the corners or edges of the selected object. Click and drag the cursor inwards towards the center of the object to activate symmetry mode. You’ll notice that as you scale the object inward, a mirrored version of the object will begin to form on the opposite side of the center point.

Step 5: Adjust the Symmetry

Continue scaling the object until the mirrored version is aligned with your desired symmetry axis. You can use SketchUp’s inference points and guidelines to ensure precise alignment. Once satisfied with the symmetry, click to confirm and finalize the transformation.

Step 6: Complete the Object

With the symmetry applied, your object should now be complete with perfect symmetry. You can further refine and edit the object as needed using SketchUp’s modeling tools.


Creating objects by symmetry or mirror imaging in SketchUp is a straightforward process that can greatly enhance the efficiency and precision of your 3D modeling projects. By following the steps outlined above and mastering the Scale and Flip Along tools, you can easily achieve balanced and uniform designs with ease. So why wait?
