Features选项卡是上下文选项卡，与map绑定。只有当application中当前活动的窗口为map时，该选项卡才会出现在功能区上。地图绘制中最常用的geometry是点、线、面、文本四种。提供了多种绘制的方法，便于满足不同的绘制需求。
The Features tab is a contextual tab bound to the map. It only appears on the ribbon when the current active window in the application is a map. The most commonly used geometries in map drawing are points, lines, polygons, and text. Multiple drawing methods are provided to meet different drawing needs.
各种geometry的绘制都在图层可编辑得状态下进行，同时设置多个图层可编辑，但是在创建点、线、面或text时，只针对当前选中的图层进行几何objects。因此，如果想要对某个图层创建新对象，必须首先单击layer manager中的相应图层，将该layer settings为当前图层。
The drawing of various geometries is performed when layers are editable. Multiple layers can be set as editable simultaneously, but when creating points, lines, polygons, or text, geometric objects are only added to the currently selected layer. Therefore, to create new objects in a specific layer, you must first click the corresponding layer in the layer manager to set it as the current layer.
