In the sand table project, not only the overall project model is dominant, but also the regional model is complementary. Whether the sand table model can be successfully shaped depends on the clear priority and importance. Both are indispensable. Because the regional model can clearly show the location of the project, the importance of this location is to let tourists have a more intuitive understanding of the location and environment of the project, which has the role of highlighting the geographical advantages of transportation. Since the regional sand table is so critical, are the materials in it particular? For the truth of the regional sand table, the effect of using different materials on the finished product is generally different.

For the design of villa landscape, the model is often composed of green vegetation and structure. The rest place, small scriptures, gardens and figures are all in a beautiful and comfortable environment. One of the most important is the configuration of plants. The requirements are caused by season, color, posture and growth characteristics. A good part of it comes from the details of plants.

The selection of materials for villa models is relatively free, because it is easy to produce results. The choice of villa type mainly depends on whether the finished product has a warm and elegant effect. In terms of material selection, organic glass is generally used, which is characterized by transparency. Light is refracted and straight. However, it is not easy to deform and break when making, which directly causes great processing difficulty. Thin wood material can also be used, but it is opaque and easy to deform, which will lead to difficulty in detail processing. Grass is the product of greening and grassland. Under the harmonious effect, it can be made into a variety of effects and is a common greening material. Instead, the simulated turf is a special material with bright colors and good texture. Then there are gypsum powder and instant paste powder, which are dried with water to become solid. As well as metal materials, various adhesive films, plasticine, standard finished products and various adhesives. In so many materials, careful analysis is required before use. Only then can the realistic effect be achieved.
