分层构造的自动造型方法针对方案设计过程由抽象到具体、由模糊到精确的特点，支持从概念到形状的方案设计全过程。分析了建筑平面布局设计过程中不同抽象层次和不同求解阶段的特点，应用分层构造的方法建立了一个以辅助方案设计为核心的建筑平面布局CAD实验系统。 The hierarchical modeling automatic modeling method supports the whole process of conceptual design from concept to shape, aiming at the design process from abstract to concrete and from fuzzy to precise. The characteristics of different levels of abstraction and different stages of the solution in the process of designing the floor plan of the building are analyzed. A CAD system of building plan layout with the core of the auxiliary plan as the core is constructed using the method of layered construction.
