1、 Visual inspection

　　在產品設計過程中，討論是非常重要的。可視化是產品設計表達的重要組成部分，是設計討論的基石。快速有效的建立產品模型可以達到更高的設計效率。與平面二維性能相比，手動板模型是不可替代的。手動模式可以使產品的細節更加清晰，產品的視覺感受更加直觀。設計團隊中的每個人都可以看到這些設計，這在協調整個團隊的工作上具有明顯的優勢。1:1手模型更直觀。設計師可以通過直接的接觸來感受設計效果，在更真實的基礎上討論設計造型，這是圖形所無法替代的。

　　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。功能測試

　　II. functional testing

　　手工模型的制作可以進行一定的功能測試，可以模擬產品的更終形態，包括功能形態、表面形態等。利用一定強度的材料(如ABS、PC等)，可以制作出包含內部結構的功能面板模型，測試產品的合理結構和壁厚。符合要求，移動部件平穩。例如，在汽車、高速列車或航天器等高速運動物體的設計中，可以將1:1的模型制作成風洞進行視覺氣動研究。

　　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，降低風險

　　Third, reduce risk

　　在設計過程中，在產品設計的早期階段，避免產品設計過程中的缺陷是非常重要的，從而避免在后續的生產中出現問題。其中，手工制作是我們可以使用的一個重要環節。R產品的顏色測試可以通過少量的成本,和重要的信息,如產品的數量和質量可以預測,可以有效地控制生產成本,包裝成本、運輸成本和原材料成本在生產中使用。手工模型是企業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.
