The Face class contains two methods that perform extrusion: pushpull and followme.
Face 类包含两个执行挤压的方法：pushpull 和 followme。
Although pushpull only extrudes in a single direction, followme extrudes in whatever direction you like.
pushpull只在一个方向上挤压，而followme则可以在任意方向上挤压。
The pushpull method is the easier of the two methods to use, and it performs the same operation as SketchUp's pushpull tool.
pushpull方法是两个方法中较容易使用的一个，它执行与SketchUp的pushpull工具相同的操作。
