If you're working with Creo and need to share your 3D models with others who may not have access to Creo software, saving your files as OBJ format can be a convenient solution. Here's how to do it:

1. Open your Creo model that you want to save as an OBJ file.

2. Go to 'File' and select 'Save As' from the drop-down menu.

3. In the 'Save As' dialog box, choose 'Wavefront Object (*.obj)' from the 'Save as type' dropdown menu.

4. Enter a file name and choose the location where you want to save the OBJ file.

5. Click 'Save' to export your Creo model as an OBJ file.

Once you've saved your Creo model as an OBJ file, you can easily share it with others, import it into other 3D modeling software, or use it for 3D printing. OBJ files are widely supported across different platforms and software, making them a versatile choice for sharing and collaborating on 3D models.

Remember that when saving your Creo models as OBJ files, certain features or complex assemblies may not be fully supported. It's a good practice to review your OBJ file in a third-party 3D software to ensure that all the necessary details and textures are preserved.

In conclusion, saving your Creo 3D models as OBJ files allows for seamless sharing and collaboration with others. It's a simple process that can greatly enhance the accessibility and versatility of your 3D models. By following the steps outlined above, you can easily export your Creo designs as OBJ files and take advantage of the wide compatibility and usability of this popular 3D file format.
