Study the conversions through 2D conceptual process to 3D materialized processing of automobile design, help the designer to understand more for communication with the CAS modeler. Based on the case of electric vehicle design for Hunan University, in terms of the aesthetic attributes theory and the key feature line extraction method, a questionnaire survey was conducted to study the similarities between the sketch of designer and the CAS models. The results were calculated from 4 different perspectives, which focused on the weight of features in each view, the consistency of expression attributes, the credibility of the expression of design sketch, and the design interpretation of CAS modelers. The results show there is ambiguity in the designer’s sketch, and variability in the 3D modeler’s interpretation. The difference in modeling idea between different modelers is caused by four main reasons. The research found that a certain range of ambiguity in design sketch and variability in 3D materialized processing based on 3D modeling parallelism show a positive effect on the possibility of design solution space. The study of design thinking between different design roles will be able to help design innovation.
