This paper presents a sketch-based modeling system for creating objects that have internal structures. The user input consists of hand-drawn sketches and the system automatically generates a volumetric model. The volumetric representation solves any self-intersection problems and enables the creation of models with a variety of topological structures, such as a torus or a hollow sphere. To specify internal structures, our system allows the user to cut the model temporarily and apply modeling operations to the exposed face. In addition, the user can draw multiple contours in the Create or Sweep stages. Our system also allows automatic rotation of the model so that the user does not need to perform frequent manual rotations. Our system is much simpler to implement than a surface-oriented system because no complicated mesh editing code is required. We observed that novice users could quickly create a variety of objects using our system.
