第一件事情就是创建建筑模型，我使用二维线来勾画墙体，天花板还有地面然后使用挤出修改器来创建他们。

First thing to do was to create the building. I used splines to define the walls, ceiling, and floors and then used the extrude modifier to create them.

你的天眼让你无需脱离体外就能感受不同维的世界。（编者注:一维线，二维面，三维静态空间，思维动态）

Your third eye gives you an opportunity to experience different dimensions without having to leave your body.

简言之，矢量数据利用最简单的拓扑实体—点、线和多边形，并在二维笛卡尔坐标系统中固定它们来描述地理特征。

In short, vector data take the simplest topological entities — points, lines, and polygons — and anchor them within a 2-d Cartesian coordinate system to describe geographical features.
