“…Although these tools are able to constrain the design according to parametric and geometric constraints set by the designer, parameter manipulation of such models is reserved for experts, who can detect and correct design problems, which range from unsatisfiable constraints to complex functional failures. Simply determining ranges of parameters where constraints are satisfiable is a known hard problem, and has only been addressed analytically for a number of severely limited scenarios [Hoffmann and Kim 2001;Van der Meiden and Bronsvoort 2006;Hidalgo and Joan-Arinyo 2012]. In addition to low-level constraints, some previous work allows setting high-level topological constraints on the realized design [van der Meiden and Bronsvoort 2007], or defining and maintaining semantic feature information during parameter manipulation [Bidarra and Bronsvoort 2000], albeit that these methods heavily rely on their chosen sets of constraints.…”

“…Para ello, es necesario utilizar una tecnología que permita modificar esta formulación en cualquier momento, y que al mismo tiempo sea capaz de transmitir automáticamente los efectos de estos cambios a la representación para su verificación inmediata. Esto incluye un sistema de visualización que dé acceso a ella, y que a su vez, sea capaz de mostrar su resultado como representación bidimensional, tridimensional, alfanumérica o de cualquier otro tipo (Hoffmann y Kimb 2001). Esta nueva forma de visualización, la del código de la representación, es la principal vía de actuación sobre el modelo, mientras que las vistas gráficas suelen ser simples medios de verificación de los resultados.…”

“…NX, CATIA, Pro/E) to create flexible reusable models. For major CAD applications, parameterization happens automatically in background processes, while the designers create the model [14]. These automatically generated parameters can then be manually modified and changed to incorporate engineering and design knowledge through applying the changed parameters to different definition equations (see Figure 2-2).…”
