How Do I Import a STL File Into SketchUp?

Importing a STL file into SketchUp can be a useful feature for 3D designers and architects. STL files are commonly used in 3D printing and are created by various CAD software programs. In this tutorial, we will guide you through the steps to import a STL file into SketchUp.

Step 1: Open SketchUp

To begin, open SketchUp on your computer. If you don’t have SketchUp installed, you can download it from the official website and install it before proceeding further.

Step 2: Access the Import Dialog

Once you have SketchUp open, click on the “File” tab in the top menu bar. From the drop-down menu, select “Import”. This will open the import dialog box.

Step 3: Select STL as File Type

In the import dialog box, navigate to the folder where your STL file is saved. In the “Files of type” drop-down menu, select “STL Files (*.stl)” as the file type.

Step 4: Adjust Import Settings

Before importing the STL file, you have the option to adjust some import settings to ensure compatibility with your design. These settings include:

  • Unit: Choose the appropriate unit for your design. This is important for maintaining accurate scale during the import process.
  • Merge Coplanar Faces: Enable this option if you want to merge coplanar faces in your design.
  • Preserve Component Hierarchy: If your STL file contains components or groups, enabling this option will preserve their hierarchy during import.

Step 5: Import the STL File

After adjusting the import settings, click on the “Import” button to import the STL file into SketchUp. The imported model will appear in your SketchUp workspace.

Step 6: Edit and Modify the Imported Model

Once the STL file is imported, you can start editing and modifying the model in SketchUp. You can use various tools and features available in SketchUp to make changes to the design according to your requirements.


In this tutorial, we have learned how to import a STL file into SketchUp. By following these steps, you can easily bring in 3D models created in other software programs and work with them in SketchUp. Now you can leverage the powerful features of SketchUp to further refine and enhance your designs.

Remember that importing complex models may impact performance, so it’s important to ensure that your computer meets the system requirements for running SketchUp smoothly. With practice and exploration of different design techniques, you’ll be able to create amazing 3D models using SketchUp!
