将3D扫描转换为可用的CAD模型并不容易。可以做到这一点的软件是一个很好的例子iron triangle规则：鉴于快速，好和便宜的选择，你只能有两个。如果你很幸运。
Up until now, engineers and designers have been faced with a choice between cheap (or free) software that does an OK (sometimes good enough) job, given a lot of time and effort, or expensive software, that does a better job, pretty quickly.
Geomagic刚刚弯曲了铁三角形，引入了Spark，一个程序，它在一个完整的应用中结合了一个直播3D扫描接口，鲁棒3D点和网格编辑功能，全面的建模设计，装配建模和2D绘图创建。它既快，也很好。
但便宜的是什么？不，Spark是专业人士的价格，而不是爱好者。尽管如此，它仍然不到一半，就像它最近的功能竞争对手一样，XOR快速。
Geomagic了解计算几何
Geomagic成立于1996年，在处理点云，网格和NURBS表面所需的数学中具有深厚背景。GeomAgic Studio是他们的高端解决方案，用于将点云转换为CAD质量NURBS模型。
Spark integrates the best of Geomagic Studio with one of the very best direct CAD programs: SpaceClaim. The result is one of those “why didn’t I think of that” products. It is easy enough to learn and use that engineers with little or no CAD background can get up to speed on it with little or no formal training. With some modest practice, an average user should be able to turn even a bad 3D scan into an accurate and manufacturable CAD model in a satisfyingly short period of time. (Let’s say, tens of minutes, rather than tens of hours.) Experienced CAD users may find themselves forever spoiled by Spark’s fluidity in creating and editing relatively complex models and assemblies.
火花生产的模型是干净，准确的NURBS的显式（非参数）B-REP固体。每个主要的MCAD系统都有能够通过直接编辑或功能识别来消耗和编辑这些模型。If, perchance, you’re interested in sending Spark models out to CAE, CAM, or CMM (inspection) applications, the situation is even better: one of SpaceClaim’s core competencies (and most popular applications) is in model preparation/simplification for CAE, CAM, and CMM. Spark also inherets SpaceClaim’s facility with PMI (product and manufacturing information) editing and 3D printing.
这是一个工作流问题
Before Spark, the process of going from a 3D scan to a usable CAD model was often tedious, but never trivial (if you wanted good results.) You had to master separate scanning and CAD applications—both of which would typically have far more options (and complexity) than you really needed to get the job done. Spark may have more capabilities than some users will require, but there seems to be little penalty in terms of usability in having these capabilities.
TheMainstreaming of3D扫描到CAD
时间是一切。新一代产品正在将专业级3D扫描仪的入口点从30,000美元到100,000美元的范围移动到一个更明智的东西。（根据您的要求，在2,000至20,000美元之间的数字。）与您的要求相同，3D打印已有利息的重生，由Makerbot和Formlab等公司等低成本产品驱动。直接CAD正在被广泛接受。这种变化的汇合正在将扫描到CAD移动到主流中。
In this context, Geomagic Spark makes a lot of sense. It provides professional-grade 3D scan-to-CAD (to print) capabilities, with great ease-of-use, and a sane price point.
