Hey there, 3D modeling enthusiasts! Want to bring some OBJ files into SketchUp? Let me show you how it's done. First, make sure you have the OBJ file ready on your computer. Open SketchUp and go to 'File' > 'Import.' In the dialog box, select 'OBJ Files' in the file type dropdown menu. Then, navigate to your OBJ file and click 'Import.' Sketchup will start the import process and may ask for some preferences. Once it's done, you'll see your OBJ file imported into SketchUp, ready for you to work your 3D magic on. Now you're all set to incorporate those OBJ files into your SketchUp projects. Happy modeling!
