在设计大型基础设施项目（如市中心地铁轨道）时，有必要考虑不同的模型比例，从公里到厘米。这个问题可以通过使用包含多个细节层次（LoD）的多尺度产品模型来解决。通过在创建模型时应用参数化建模技术，可以确保不同LoD之间的一致性。然而，约束和依赖关系的正确应用已被证明过于复杂，无法手动处理。为了解决这个问题，本文提出了一种自动细化机制，这是基于使用的图形和图形转换。我们展示了如何基于二维草图的程序参数化模型可以用图形表示，以及如何通过这种图形的基于规则的转换来实现细化步骤。
During the design of large infrastructural projects like inner-city subway tracks, it proves necessary to consider differing model scales, ranging from kilometers to centimeters. This problem can be addressed by using multi-scale product models comprising multiple levels of detail (LoD). Ensuring consistency across the different LoDs can be achieved by applying parametric modeling techniques while creating the model. However, the correct application of constraints and dependencies has shown to be too complex to be handled manually. To address this issue, this papers presents an automated detailing mechanism, which is based on the use of graphs and graph transformations. We show how procedural parametric models based on two-dimensional sketches can be represented by graphs and how refinement steps can be realized through the rule-based transformation of such a graph.
