By various kinds of software, models are built quickly with the detailed requirement. Nowadays, the modeling speed has become faster than before; however, it still takes more time to finish in a large scale. This study is based on 2 ways, passive and initiative modeling simulation.Using SketchUp and PhotoScan to build the 3-dimensional cyber city model of southern Taichung City, and compared the time, acreage, accuracy and cost of construction at the same time. This study offers a method of building a model. Taking the southern Taichung city as an instance,it costs less time with PhotoScan,building up the acreage 994 times larger than SketchUp within 1 hour,while reaches the same accuracy as SketchUp does, hence build up the model fast.
