“…Users often have few possibilities to control the resulting shapes. The second category includes the freeform features that are defined by free-form surfaces obtained through the use of techniques expressing a homogeneous behaviour over the whole surfaces [4], [5]. They provide freedom but handling the modified area is not always as free as possible.…”

Even if today's CAD systems can easily represent free-form shapes by means of NURBS surfaces, their definition and modification still require a deep knowledge and a great skill in the manipulation of the underlying mathematical models. This paper presents an attempt to bring the feature concepts, well-known in the classical mechanical domain, to the free-form domain. The paper extends our previous work on fully free-form features to include parameterised feature templates. The free-form shapes are obtained by deformation according to specific constraint lines taking part to the feature templates definition. The feature template is adapted to the user-specified parameter values by our deformation engine, which can applied either to surfaces and curves. The method is illustrated with examples obtained with our prototype software.

AbstractThis paper addresses the designers' activity and in particular the way designers express an object shape in 2D sketches through character lines and how these lines form a basis for sketching shapes in 3D. The tools currently available in commercial CAS/CAD systems to manipulate the digital models are still not sufficiently suited to support design. In this paper, the so-called fully free-form deformation features (d-F 4 ) are introduced as a modelling method to take into account the curve-oriented stylists' way of working. Both the advantages of a free-form surface deformation method and a feature-based approach are merged to define these high-level modelling entities allowing for a direct manipulation of surfaces through a limited number of intuitive parameters. Such features incorporate several characteristics designed to handle the uncertainties and/or inconsistencies of the designer's input during a sketching activity. In addition, a d-F 4 classification is proposed to enable a fast access to the desired shape according to its semantics and characteristics.

“…This property depends on the application context where the notion of inside/outside can be either defined or not, together with the surface orientation, -topological positioning, it characterizes the BSFs according to their position relatively to the boundary of an open surface. Three cases can be identified: internal when the feature is completely inside the surface, channel when the feature crosses the surface boundaries and border when the feature is placed at the boundary [19].…”

Different methods for free-form surface deformation have been developed in the last years to overcome difficulties in direct manipulation of surfaces. Even if these approaches are real improvements in the design workflow, they are still far from the stylists' requirements whose main target is the aesthetic shape. Feature-based approaches have been introduced to provide users with more intuitive tools improving interactivity without reducing their creativity. To couple the advantages of both approaches here we propose a hierarchical free-form features classification built on top of our surface deformation tool, where so-called Basic Shape Features and High Level Features form the two main classes on which basis a feature taxonomy is defined according to morphological and topological criteria.
