If you're an architect, interior designer, or anyone who works with 3D models, you know the importance of being able to showcase your designs in an interactive 3D environment. SketchUp is a powerful tool for creating 3D models, and it's essential to know how to save and view your creations in 3D. Here's how you can do it: 1. Save your SketchUp file: Before you can view your model in 3D, you need to save your SketchUp file. Go to 'File' -> 'Save As' and choose a location on your computer to save the file. 2. Export as a 3D file format: Once your file is saved, you need to export it in a 3D file format that allows for interactive viewing. SketchUp supports various 3D file formats such as .dae, .kmz, .fbx, and .obj. Choose the format that best suits your needs and select 'File' -> 'Export' to save your model in that format. 3. Use a 3D viewer: After exporting your model in a 3D file format, you can use a 3D viewer to showcase your design. There are many 3D viewer tools available online that allow you to upload your 3D model and view it in an interactive 3D environment. Some popular 3D viewers include Sketchfab, p3d.in, and Clara.io. These platforms allow you to upload your 3D model and share it with others, making it easy to showcase your designs. By following these steps, you can save your SketchUp files and view them in 3D to present your designs in an interactive and engaging way. Whether you're creating architectural models, interior designs, or product prototypes, being able to view your creations in 3D will help you communicate your ideas effectively and impress your clients or colleagues.
