There is a tutorial available on the official website that helps new users manage all the basics in a little over fifteen minutes. In any case, once you gain experience with the program you'll be able to convert any element of which you have at least four or five photos into a 3D object in about ten minutes.
Once you're done working on your object, you can save the project in Insight 3D format, or export it into several different formats, such as VRML.
Insight 3D is a 3D object creation tool that won’t let you create an object from scratch, but will help you work on more complex objects, making it simpler and easier. All you'll need is a good camera.
