论文摘要
草图设计概念是参数CAD草图中发现的重复图案。尽管CAD设计师很少明确地将这些概念隐式用于模块化和规律性。在本文中，我们提出了一种基于学习的方法，该方法通过对原始草图的归纳来发现模块化概念。我们提出了概念结构的双隐式解释表示，该表示概念结构允许隐式检测和显式产生，以及对参数化概念生成的结构生成和参数实例化的分离，以通过端到端培训学习模块化概念。我们在大型CAD草图数据集上演示了设计概念学习，并展示了其设计意图解释和自动完成的应用。
Sketch design concepts are recurring patterns found in parametric CAD sketches. Though rarely explicitly formalized by the CAD designers, these concepts are implicitly used in design for modularity and regularity. In this paper, we propose a learning based approach that discovers the modular concepts by induction over raw sketches. We propose the dual implicit-explicit representation of concept structures that allows implicit detection and explicit generation, and the separation of structure generation and parameter instantiation for parameterized concept generation, to learn modular concepts by end-to-end training. We demonstrate the design concept learning on a large scale CAD sketch dataset and show its applications for design intent interpretation and auto-completion.
