The sand model is one of the most commonly used tools in the construction industry. However, since sand models are mainly used in the design field and are less utilized in other areas, many people are not familiar with them. The main feature of the sand model is that it can combine imagery and specificity. Because many elements in the sand model have certain representativeness, during the operation of the sand model, many things are practical exercises. 

Due to this characteristic, sand model has some related functions during its use, especially in the design process of the construction industry. Because the design work in the construction industry is very important, it is the most crucial thing we should do before the construction. However, during such a process, we will find that drilling the sand model is a very important thing in the construction process, and the matters during the construction are also very important. 

1. Perfect Design Concept: Model making is the process of further improving and optimizing the design. When the designer creates the model themselves, it is an experience transitioning from a two-dimensional plane to a three-dimensional image. Through personal experience and participation in the production process, designers can be further inspired, identify problems in the design, and improve and optimize the design, so that the design proposal can reach the ideal state. 

2. Construction Guidance: If the construction unit has difficulty understanding or misinterpreting the floor plan and elevation drawing, it will cause construction difficulties and ultimately affect the realization of the design effect. Utilizing physical models to showcase the characteristics of the design is beneficial for construction enterprises to carry out construction according to the design intention. The intuitive and vivid models have a very good guiding role in engineering construction. 

3. Expression of Design Effects: The physical model is an excellent way to present the design features to the audience and is an important means for the designer to communicate with the client. 

4. Reducing Design Risks: Model production is one of the crucial steps in the design process, which can minimize design risks to the greatest extent and has practical significance for determining the design positioning and ensuring construction and production. 

The role of building sand model is quite significant, and this is the reason why the model industry has become so popular. Currently, there are professional sand model companies in China that produce sand models. Jingtuo Model is one of the leading authoritative enterprises in this field. The company has been providing model design and model production services for many years. The successful experience accumulated in the exploration and practice of digital sand models, intelligent sand models, architectural models, industrial models, planning models, exhibition hall models, and scheme models has exceeded the level of industry peers.
