我们提出了一个全面的系统，作者平面截面结构，共同在艺术和工程。一项关于如何想象和绘制平面截面组件的研究指导了我们的设计原则：平面截面最好在原位绘制，几乎没有透视缩短，与相交的平面截面正交，表现出平面和轮廓之间的交叉。我们捕捉这些原则与一个新的绘图工作流程，其中一个单一的流体用户中风指定一个3D平面和它的轮廓与现有的平面部分。通过定义相交平面截面的程序操作词汇表来支持规则性。我们利用平面结构的属性，提供实时的视觉反馈的物理模拟应力，几何验证的结构是稳定的，连接，可以组装。这种反馈通过真实世界的制造和测试来验证。作为评估，我们报告了50多名受试者，他们都使用我们的系统，以最少的指令创建独特的模型。
We present a comprehensive system to author planar section structures, common in art and engineering. A study on how planar section assemblies are imagined and drawn guide our design principles: planar sections are best drawn in-situ, with little foreshortening, orthogonal to intersecting planar sections, exhibiting regularities between planes and contours. We capture these principles with a novel drawing workflow where a single fluid user stroke specifies a 3D plane and its contour in relation to existing planar sections. Regularity is supported by defining a vocabulary of procedural operations for intersecting planar sections. We exploit planar structure properties to provide real-time visual feedback on physically simulated stresses, and geometric verification that the structure is stable, connected and can be assembled. This feedback is validated by real-world fabrication and testing. As evaluation, we report on over 50 subjects who all used our system with minimal instruction to create unique models.
