We propose modeling operations using a volume-based cut-and-paste method for generating rough 3D models. Cut-and-paste editing extracts a characteristic feature from a source model and copies it to a target model. To create such a cut-and-paste technique, we developed a new method that consists of mesh segmentation and volume fitting. In our method, a feature region and its surrounding area are separated from the user-specified area and are used for generating a parametric volume that involves the feature region. In feature pasting, parametric volumes are deformed and pasted to the target model, and then, features inside the volume are adaptively deformed and pasted to the target. Our experimental results show our operations can effectively generate new models by removing, pasting, and deforming partial shapes in existing models.
