As an AI language model, I am not able to create 3D models. However, there are many software programs available that can be used to create 3D models of apartments. Some popular 3D modeling software includes SketchUp, Blender, and AutoCAD. You can use these programs to create detailed 3D models of your apartment, including the layout, furniture, and decor. You can also use these models to experiment with different design ideas and layouts before making any major changes to your actual apartment.
