本文提出了针对汽车概念设计阶段详细阐述基于语义的建模环境的第一步。迄今为止，美学设计中的形状生成和操作仍然基于来自经典 CAD（计算机辅助设计）范式的低级几何工具。另一方面，产品的设计主要由设计师的创造力和高层约束驱动。因此，这样的环境首先基于嵌入汽车第一个 2D 草图中的语义结构。为了操作此类草图，集成了过程语法来描述和操作曲线。最后，该语法通过使用适合 NURBS 曲线的变形引擎来实现。 MOTS-CLÉS：概念审美、模型化语义、形式变形、2D 分析、库尔布变形操作。
This paper presents a first step in the elaborati n of a semantic-based modelling environment addressed to the conceptual design phas e of a car. Up to now shape generation and manipulation in aesthetic design are still base d on low-level geometric tools that come from the classical CAD (Computer-Aided Design) paradi gm. On the other hand, the design of a product is mainly driven by designers’ creativ ity and high-level constraints. As a consequence, such environment is based first on a s tructuration of the semantics embedded in the first 2D sketches of the car. To manipulate suc h sketches, a process grammar has been integrated to describe and manipulate the curves. F inally this grammar has been implemented through the use of a deformation engine adapted to NURBS curves.
