“…This always includes the generic shape of the feature, and a number of parameters, e.g., length, width, and constraints, e.g., parallel, perpendicular, that describe this shape. By specifying values for the parameters, an instance of the feature class can be created and then added to a feature model [14]. A feature-based model usually contains the description of the part in terms of its constituting feature instances, the information related to their mutual dependencies and the chronology of construction.…”

“…; consequently, features are intended as complex high level entities that allow a faster creation and modification of the geometric model. In literature, it is possible to find several studies focusing on the user interactions with shape product through free-form features [12]; there are various meaningful proposal for classification of free-form features [2][7] [16], and several interesting works [13][18] dealing with the shape modification by features but they are hardly taking into account aesthetic information; only few consider aspects, such as brand character or emotional feeling but are very peculiar to specific products and not generally applicable. Defining a strict link between geometric characteristics and aesthetic features is not immediate due to the multitude of the possible shapes and to the fuzziness of the concept of aesthetics.…”

ABSTRACTTo better simulate the way designers work, specific tools are needed to handle directly specific shape features meaningful for the design intent, without focusing on the underlying mathematic representation. For this purpose it is fundamental to identify proper higher-level shape descriptors as well as the corresponding manipulation techniques. The paper presents the definition and implementation of semantic operators for curve deformation based on a shape characterization that is specific to the industrial design context. The work grounds on the innovative approach suggested by the FIORES-II project for the intent-driven modeling tools for direct shape modification and on the multi-layered architecture proposed by the Network of Excellence AIM@SHAPE for the definition of semantic-oriented 3D models. In particular the paper proposes the use of meaningful aesthetic features for the evaluation of planar curve signature and for their intent-driven direct modification.

“…Especially for humerus and radius, the result of the matching directly affects the upper limb movement function recovery of patients. In order to satisfy this requirement, the abutted surface of fixation plate is taken directly from the region-of-interest of the 3D reconstruction model [21][22][23][24][25]. Then, a fixation plate is generated through thickening the abutted surface.…”

The purpose of this paper was to quickly design fixation plates for fractured proximal humerus and distal radius according to the requirements of surgical treatment. Therefore, a new method to quickly design cloverleaf plate appropriate for proximal humerus and volar plate appropriate for distal radius is put forward. First, three-dimensional (3D) reconstruction models of fractured proximal humerus and distal radius were generated based on deforming mean parametric models of proximal humerus and distal radius, respectively. Second, based on region-of-interest marked on the 3D reconstruction model of proximal humerus and distal radius, abutted surfaces of cloverleaf plate and volar plate were established, respectively. Then, parametric abutted surface was established after setting rational parameters for the surface of the cloverleaf plate. Parametric abutted surface of volar plate was established using the same method. Finally, parametric cloverleaf plate and volar plate are generated through thickening their respective parametric abutted surfaces. The parametric plates, acting as templates, accelerate and simplify the design process and therefore allow users to construct plate with editing valid parameters easily. Group of cloverleaf plates and volar plates with different sizes were generated quickly, showing that the proposed method is feasible and effective.
