Hey there! Are you struggling to export your 3D models with materials as OBJ files in Fusion 360? Don't worry, I've got you covered. Here's a simple guide to help you out.

Step 1: Open your 3D model in Fusion 360 and make sure you've assigned materials to different parts of the model. This is essential for exporting OBJ files with materials.

Step 2: Once your model is ready, go to the 'File' menu and select 'Export'. Choose 'OBJ' as the file type and specify the desired location to save the file.

Step 3: Before exporting, make sure to check the option 'Include Materials' in the export settings. This will ensure that your OBJ file retains the assigned materials from Fusion 360.

Step 4: Click 'OK' to export the OBJ file with materials. Now, you can use this file in other 3D modeling software or share it with others while preserving the materials.

That's it! You've successfully exported your 3D model with materials as an OBJ file in Fusion 360. I hope this guide helps you with your 3D modeling projects. Happy designing!
