Revit中Category的获取

开发基础代码

UIDocument uidoc = commandData.Application.ActiveUIDocument;
Document doc = uidoc.Document;
UIApplication uiapp = commandData.Application;
Application app = uiapp.Application;

获得单一类别

以墙为例
方法一：Category wallCategory  = doc.Settings.Categories.get_Item(BuiltInCategory.OST_Walls); 
方法二： Category wallCategory  =Category.GetCategory(doc, BuiltInCategory.OST_Walls);
方法三：Category wall3=Category.GetCategory(doc, new ElementId(-2000011));

获取类别后就可以得到其他参数
wallCategory .Name就是类别名：墙

wallCategory  .CategoryType就是类别类型：Model（模型）

(BuiltInCategory)cat.Id.IntegerValue：OST_Walls 

获取当前文档所有的Category

Categories cats = doc.Settings.Categories; 

备注：对于所有revit文档来说，类别定了ElementId也就定了，如墙的为-2000011，不随项目不同而变化。

在此列出所以Category的ElementId：反编译其他文档一般只能看出Id，通过这个可以反推出类别来。其他的枚举类型如BuiltinParameter类似。
