You can import floor plans from other cad software, and design an interior layout with the sketchup 3d warehouse. they have thousands of parts/items for interior design that you can input into your drawing. You can also create your furniture and add graphics within the software. Best of all, the software has a wide variety of textures, materials and colors that you can use for your design, and rendering it makes it a lot more realistic.
