1、 Visual inspection

　　在产品设计过程中，讨论是非常重要的。可视化是产品设计表达的重要组成部分，是设计讨论的基石。快速有效的建立产品模型可以达到更高的设计效率。与平面二维性能相比，手动板模型是不可替代的。手动模式可以使产品的细节更加清晰，产品的视觉感受更加直观。设计团队中的每个人都可以看到这些设计，这在协调整个团队的工作上具有明显的优势。1:1手模型更直观。设计师可以通过直接的接触来感受设计效果，在更真实的基础上讨论设计造型，这是图形所无法替代的。

　　In the process of product design, discussion is very important. Visualization is an important part of product design expression and the cornerstone of design discussion. The rapid and effective establishment of product model can achieve higher design efficiency. Compared with the planar two-dimensional performance, the manual plate model is irreplaceable. The manual mode can make the details of the product clearer and the visual feeling of the product more intuitive. Everyone in the design team can see these designs, which has an obvious advantage in coordinating the work of the whole team. 1: 1 hand model is more intuitive. Designers can feel the design effect through direct contact and discuss the design modeling on the basis of more reality, which is irreplaceable by graphics.

　　二世。功能测试

　　II. functional testing

　　手工模型的制作可以进行一定的功能测试，可以模拟产品的更终形态，包括功能形态、表面形态等。利用一定强度的材料(如ABS、PC等)，可以制作出包含内部结构的功能面板模型，测试产品的合理结构和壁厚。符合要求，移动部件平稳。例如，在汽车、高速列车或航天器等高速运动物体的设计中，可以将1:1的模型制作成风洞进行视觉气动研究。

　　The production of the manual model can carry out some functional tests and simulate the final form of the product, including functional form, surface form, etc. Using certain strength materials (such as ABS, PC, etc.), we can make a functional panel model including the internal structure, and test the reasonable structure and wall thickness of the product. Meet the requirements, and the moving parts are stable. For example, in the design of high-speed moving objects such as cars, high-speed trains or spacecraft, the 1:1 model can be made into wind holes for visual aerodynamic research.

　　第三，降低风险

　　Third, reduce risk

　　在设计过程中，在产品设计的早期阶段，避免产品设计过程中的缺陷是非常重要的，从而避免在后续的生产中出现问题。其中，手工制作是我们可以使用的一个重要环节。R产品的颜色测试可以通过少量的成本,和重要的信息,如产品的数量和质量可以预测,可以有效地控制生产成本,包装成本、运输成本和原材料成本在生产中使用。手工模型是企业控制成本的有效方法。

　　In the design process, in the early stage of product design, it is very important to avoid defects in the product design process, so as to avoid problems in the subsequent production. Among them, manual production is an important link we can use. The color test of R product can pass a small amount of cost and important information, such as the quantity and quality of product can be predicted, which can effectively control the production cost, packaging cost, transportation cost and raw material cost in production. Manual model is an effective method to control cost.
