随着消费级3D打印的日益普及,许多人正在创建,甚至更多地使用在Thingiverse等网站上共享的对象。然而,我们对962个Thingiverse模型的形成性研究表明,模型缺乏重用,这可能是由于3D建模所需的高级技能。需要一个最终用户程序对3D建模的看法。我们的框架(PARTs)使业余建模者能够通过几何图形指定设计意图。PARTS包括一个GUI、脚本API和用于测试设计预期的断言范例库,以及用于创建几何图形的集成器。PARTS允许建模人员将高级的、特定于模型的功能集成到设计中,这样它们就可以被重用和扩展,而无需编程。在两个研讨会中,我们展示了PARTS有助于创建3D打印模型,并且比使用标准工具更容易修改现有模型。
With the increasing popularity of consumer-grade 3D printing, many people are creating, and even more using, objects shared on sites such as Thingiverse. However, our formative study of 962 Thingiverse models shows a lack of re-use of models, perhaps due to the advanced skills needed for 3D modeling. An end user program perspective on 3D modeling is needed. Our framework (PARTs) empowers amateur modelers to graphically specify design intent through geometry. PARTs includes a GUI, scripting API and exemplar library of assertions which test design expectations and integrators which act on intent to create geometry. PARTs lets modelers integrate advanced, model specific functionality into designs, so that they can be re-used and extended, without programming. In two workshops, we show that PARTs helps to create 3D printable models, and modify existing models more easily than with a standard tool.
