When we look at a sand table model, we will look at the structure of the sand table as a whole. The deficiencies in each place will affect the overall effect. Just like a bucket holding water, only when the height of each board is the same can it be filled with water. If one of the boards is short, it will affect the water holding capacity of the whole bucket.

而底盘的制作也是如此，如果底盘的制作的不好，别的部位做的再好，也会影响整体效果。下边我们将给大家介绍下建筑模型中的底盘。

The same is true for the production of chassis. If the production of chassis is not good, no matter how well other parts are done, the overall effect will also be affected. Next, we will introduce the chassis in the building model.

我们经常看到建筑模型，但是它的底盘是什么材料做的，你留意过吗？你一定会说是木头的或者是塑料的，其实你答对了一半。

We often see building models, but what material is the chassis made of? Have you noticed? You must say it's wood or plastic. In fact, you're half right.

建筑模型的底盘通常是由PS板、KT板和木质底盘做的，还有天然石材、玻璃、石膏等。PS（聚苯乙烯板）与KT板具有质地轻、任性好、不变形等优点，是普通纸材模型的好的材料。然而，成品PS板和KT板的切面难以磨平整，需要应用厚纸板、瓦楞纸或者其他装饰型材封边处理，保持外观光洁。

The chassis of building model is usually made of PS board, KT board and wooden chassis, as well as natural stone, glass, gypsum, etc. PS (polystyrene board) and KT board have the advantages of light texture, good willfulness and no deformation. They are good materials for ordinary paper models. However, the section of the finished PS board and KT board is difficult to smooth, so it needs to be edge sealed with thick cardboard, corrugated paper or other decorative profiles to keep the appearance clean and bright.

底盘是建筑模型的重要组成部分，它对主体模型起支撑作用。平整、稳固、宽大是模型底盘制作的基本原则，在具体制作中还要考虑建筑模型的整体风格、制作成本等因素。木质底盘质地浑厚，一般会保留原始木纹，或在表面钉接薄木装饰板，装饰风格要与建筑模型主体相衬映，板材边缘仍须钉接或者粘贴饰边，避免底盘边角产生开裂。

Chassis is an important part of building model, which supports the main model. Flat, stable and wide are the basic principles for the production of the model chassis. In the specific production, the overall style of the building model, production cost and other factors should be considered. The wooden chassis has a thick texture. Generally, the original wood grain will be retained or the thin wood decorative board will be nailed on the surface. The decorative style should be set off with the main body of the building model. The edges of the board must still be nailed or pasted with decorative edges to avoid cracking at the edges and corners of the chassis.

无论哪种材料的选择，都是为了使建筑模型的底盘起到装饰效果，衬托起整个沙盘模型。底盘做的好，不仅会使整个沙盘模型显得高大上，还会为整个沙盘起到锦上添花的作用。

No matter which material is selected, it is to make the chassis of the building model play a decorative effect and set off the whole sand table model. A good chassis will not only make the whole sand table model look tall, but also add icing on the cake to the whole sand table.
