Here's how it works: on the model details page (the one with the large picture of the model and its description) there are now two buttons marked "Image" and "3D View". Click the "3D View" option, wait a moment, then you can click and drag left or right to spin the model. Pretty simple stuff.
When you upload a new model or update an existing one, we have to modify a couple of things before your "3D View" images can be seen. After uploading, check back in a day or two and the images should be ready to go. Okay, now head back to the 3D Warehouse and enjoy the ride!
