摘要

今天的CAD程序不只是产生令人兴奋的图形图片或令人信服的虚拟模型,可以交互操作和更改。由于许多分层制造技术的发展以及诸如Shapeways[2011]和Ponoko[2011]等服务的出现,它们也可以产生有形的物理工件。创建、操作和研究这样的3D工件为设计过程增加了一个全新的反馈循环。这种额外的经验对计算机辅助设计的教学也非常有用。在一门关于实体建模和快速原型的研究生课程中,我们使用了解剖谜题的设计和实现作为训练工具。解剖谜题是特别有价值的设计对象,因为它们不仅训练空间理解,而且还以非常“动手”的方式推动有关精度和公差的问题。在这张海报和附带的模型中,我们展示了我们研究过的一些解剖模型,并阐明了与每种类型相关的建模问题。

Interactive 3D rapid-prototyping models
Today CAD programs are not just producing mind-blowing graphics pictures or convincing virtual models that can be interactively manipulated and changed. They also can yield tangible, physical artifacts, thanks to the development of many layered manufacturing techniques and the emergence of services such as Shapeways [2011] and Ponoko [2011],. Creating, manipulating, and studying such 3D artifacts adds a whole new loop of feedback to the design process. This extra experience is also highly useful in the teaching of computer-aided design. In a graduate course on Solid Modeling and Rapid Prototyping we have used the design and realization of dissection puzzles as a training tool. Dissection puzzles are particularly valuable design objects, since they not only train spatial understanding, but they also drive home issues concerning accuracy and tolerances in a very "hands-on" manner. In this poster and in the accompanying models we demonstrate some of the dissection models that we studied and elucidate the modeling issues associated with each type.
