If you're using SketchUp Free for your 3D modeling projects, you may run into the need to export your models in a different file format, such as OBJ. OBJ files are commonly used for sharing 3D models across different software platforms or for 3D printing.

To save your SketchUp Free models as OBJ files, you'll need to follow these steps:

Step 1: Open your SketchUp Free model in the web browser.

Step 2: Go to the 'File' menu and select 'Export' > '3D Model'.

Step 3: In the export options, choose 'OBJ' as the file format.

Step 4: Adjust any other export settings, such as units and scale, as needed.

Step 5: Click 'Export' to save your model as an OBJ file.

After following these steps, your SketchUp Free model will be saved as an OBJ file, ready for use in other 3D modeling programs or for 3D printing.

Keep in mind that while SketchUp Free offers the ability to export models as OBJ files, there may be limitations or differences in the exported file compared to the original SketchUp model. It's always a good idea to check the exported OBJ file in the intended destination software or 3D printer to ensure it meets your expectations.

By understanding how to save SketchUp Free models as OBJ files, you can expand the versatility of your 3D modeling projects and collaborate with others using different software platforms. Whether you're working on architectural designs, product prototypes, or artistic creations, the ability to export your models in different file formats can be a valuable skill in the world of 3D modeling and design.

So, next time you find yourself needing to share your SketchUp Free creations with others or incorporate them into a larger 3D project, remember that exporting your models as OBJ files is a straightforward process that opens up new possibilities for your work.
