... A 'skeleton' is a basic concept in CAD modelling of machines and mechanisms (Held et al., 2016;Ju et al., 2007). A CAD skeleton contains the structure and the form of the future product (Bluntzer et al., 2016) (Ostrosi et al., 2020). Many studies have already been carried out using skeleton-based modelling (Cornea et al., 2005(Cornea et al., , 2007Levet and Granier, 2007;Li and Lachmayer, 2019;Schubert et al., 2011;Wade and Parent, 2002;Ziegler and Wartzack, 2013). ...
... Corner, s-shaped, and break lines can describe the form's characteristics [20]. Next, from the designer's perspective, defining the meaning of shape description terms, such as radius, straight/flat, and s-shaped, is necessary to modify the appearance shape by adding or subtracting lines with corresponding characteristics [21]. Based on this approach, we deconstruct the key lines of the car-front facing form ( Figure 4) and propose three elements of the car facing form's style, containing rounded lines, sharp lines, and straight lines. ...
... Fleche et al. use quantitative and non-intrusive indicators during the management of collaborative design phases. They compute several indicators linked to the completeness of the CAD data in order to assess the performance of a collaborative design project (Fleche et al., 2017). Fleche makes the hypothesis that the completeness rate of the project can be measured by taking into account the modification rate of CAD data between two revisions. ...

... Globalization of the economy has brought about the tendency in the market to reduce the product cost, decrease time of process and production, increase the product performance and pursue user satisfaction (Bluntzer et al. 2009). Many product developers are under pressure and facing difficulties when developing new products. ...
... However, there are remarkable differences [8] between the management of engineering changes in engineering design projects and configure-to-order mode. Most requests for changes arise because stakeholders' knowledge has not been integrated into the design process [9]. Fleche et al. argue that the use of collaborative tools, such as digital manufacturing, can reduce the emergent changes in the later NPD phases when it is used early enough. ...
... Brangier defines use as the effective application of a product in a social context (Brangier and Barcenilla, 2003). Thus use can be considered as the interaction between the product, the user and the ICED19 context (Al Khatib et al., 2014). Like the product, it is an artefact that can be designed and its design process consists in descriptive proposals satisfying requirements (Rasoulifar et al., 2007). ...
... A study with European engineer students from ergonomic, design, and mechanical engineering departments, demonstrated that cars from their home continent were easily recognized, whereas Japanese cars were difficult to recognize, and some cars coming from the USA, such as the Ford F-Series, were somewhat recognizable (Bluntzer, Ostrosi, & Sagot, 2014a). A similar experiment considering the role of design freedom and brand recognition for automotive designs from four brands found that while brand recognition is highly dependent on the manufacturer, some brands develop a strong negative relationship between design freedom and brand recognition, suggesting that these manufacturers face a significant challenge when evolving their brand styling (Burnap, Hartley, Pan, Gonzalez, & Papalambros, 2016). ...
... Le nouveau critère que nous avons suivi et illustré ici est donc la donnée numérique qui va évoluer dans le temps et être modifiée par les phases de travail collaboratif (Fleche, et al., 2014a). Dans l'état de l'art nous avons nommé cette notion la complétude afin de la différencier du terme maturité qui réfère à l'état de l'information qui est échangée entre les acteurs projet (Saint-Marc, et al., 2004). ...
