Revit二次开发（5）:元素类型过滤

下面是获得文档中所有族实例的代码，简单演示用法：

ElementClassFilter instanceFitler = new ElementClassFilter(typeof (FamilyInstance));

FilteredElementCollector collector = new FilteredElementCollector(doc);

collector.WherePasses(instanceFitler);

List familyInstances = new List();

foreach (Element element in collector.ToElements())

{

    if (element is FamilyInstance)

    {

        familyInstances.Add(element as FamilyInstance);

    }

}

return familyInstances;

具体用法请参考官方例子。

官方例子名称：DirectionCalculation
