在着手制作沙盘模型时，首先必须考虑的恐怕是模型的“利用方法”或者说“表现方法”问题，按照“利用方法”便可确定方针，比例等。城市规划，住宅区规划等大范围的沙盘模型，比例一般为1/3000--1/5000，楼房等模型物则常为1/200--1/50，通常是采用与设计图相同的比例者居多。另外，若是住宅模型，这与其他建筑物的情况稍有不同，如果建筑物不是很大，则采用1/50，竟可能让人看得清楚。一般情况下，制作顺序是先确定比例，比例确定后，先做出建筑保定平面设计培训 保定室内设计培训 保定空调移机 保定太阳能维修 保定厨房排烟 雄安管道通风 用的场地模型，沙盘模型的制作者也必须清楚地形高差，景观印象等，通过大脑进行计划立意处理，然后再多作几次研究分析，就可以着手制作沙盘模型了。
When making a sand table model, I'm afraid the first thing to consider is the "utilization method" or "performance method" of the model. The policy and proportion can be determined according to the "utilization method". For large-scale sand table models such as urban planning and residential area planning, the proportion is generally 1 / 3000-1 / 5000, and the model objects such as buildings are often 1 / 200-1 / 50. Most of them adopt the same proportion as the design drawing. In addition, if it is a residential model, it is slightly different from that of other buildings. If the building is not very large, it may be seen clearly by using 1 / 50. In general, the production order is to determine the proportion first. After the proportion is determined, the site model for construction is made first. The producer of the sand table model must also know the terrain elevation difference and landscape impression, carry out planning and intention processing through the brain, and then make more research and analysis, so as to start making the sand table model.
