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.

而底盤的制作也是如此，如果底盤的制作的不好，別的部位做的再好，也會影響整體效果。下邊我們將給大家介紹下建筑模型中的底盤。

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.

我們經(jīng)常看到建筑模型，但是它的底盤是什么材料做的，你留意過嗎？你一定會說是木頭的或者是塑料的，其實你答對了一半。

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.

建筑模型的底盤通常是由PS板、KT板和木質(zhì)底盤做的，還有天然石材、玻璃、石膏等。PS（聚苯乙烯板）與KT板具有質(zhì)地輕、任性好、不變形等優(yōu)點，是普通紙材模型的好的材料。然而，成品PS板和KT板的切面難以磨平整，需要應(yīng)用厚紙板、瓦楞紙或者其他裝飾型材封邊處理，保持外觀光潔。

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.

底盤是建筑模型的重要組成部分，它對主體模型起支撐作用。平整、穩(wěn)固、寬大是模型底盤制作的基本原則，在具體制作中還要考慮建筑模型的整體風(fēng)格、制作成本等因素。木質(zhì)底盤質(zhì)地渾厚，一般會保留原始木紋，或在表面釘接薄木裝飾板，裝飾風(fēng)格要與建筑模型主體相襯映，板材邊緣仍須釘接或者粘貼飾邊，避免底盤邊角產(chǎn)生開裂。

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.

無論哪種材料的選擇，都是為了使建筑模型的底盤起到裝飾效果，襯托起整個沙盤模型。底盤做的好，不僅會使整個沙盤模型顯得高大上，還會為整個沙盤起到錦上添花的作用。

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.
