Parametric Modeling

Christoph M. Hoffmann and Robert Joan-Arinyo

Parametric solid modeling is a key technology to define and manipulate solid models through high-level, parameterized steps. These steps can be modified by users and instantiated to specific parameter values and constraint configurations. More than that, the design paradigm supported allows the shape designer to define entire families of shapes, not just specific instances. We review the core techniques of parametric modeling, describe new trends, and sketch a number of open problems that must be resolved to take full advantage of the potential of parametric modeling.


A parametric solid can be defined as a solid whose actual shape is a function of ...
