如何计算所有元素类似于FilteredElementCollector符号特殊设备的家族？

当我使用 DesignAutomation (Autodesk Forge) 通过获取 FilteredElementCollector lstEleCollector = new FilteredElementCollector (doc, doc.ActiveView.Id); 来计算 Revit 文件中可见的 BuiltInCategory.OST_SpecialityEquiosystem 元素的数量时但我意识到设计自动化中没有Active View概念。那么有没有办法统计rvt文件中出现的所有元素呢？

要计算文档中给定类别的所有元素，您应该使用：

FilteredElementCollector collector = new FilteredElementCollector(doc);
ICollection<Element> collection = collector.OfCategory(BuiltInCategory.OST_SpecialityEquiosystem)
    .ToElements();
int count = collection.Count;

但是，这将为您提供文档中的所有元素。要在给定视图中找到元素，您需要知道视图ID。如果您不知道视图ID，则可以迭代文档中的所有视图并找到所需的视图。

FilteredElementCollector collector = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Views);
foreach (Autodesk.Revit.DB.View v in collector.ToElements())
{
    if (v && v.Name == "My Special View")
        viewId = v.Id;
}

然后，您可以使用此 viewID 而不是 doc.activeview.id 来调用您已经知道的API。

FilteredElementCollector lstEleCollector = new FilteredElementCollector (doc, viewId);
ICollection<Element> collection = lstEleCollector.OfCategory(BuiltInCategory.OST_SpecialityEquiosystem)
    .ToElements();
int count = collection.Count;

还请参考我们的非常基本的 forge-countdeleteblewalls-revit- revit 代码代码执行类似的示例您正在尝试的事情。它在给定文档中计算墙壁，门，地板和窗户。

To count all elements of a given category in a document you should use FilteredElementCollector.OfCategory():

FilteredElementCollector collector = new FilteredElementCollector(doc);
ICollection<Element> collection = collector.OfCategory(BuiltInCategory.OST_SpecialityEquiosystem)
    .ToElements();
int count = collection.Count;

This will however give you all elements in the document. To find elements in a given view, you will need to know the view id. If you do not know the view id, you can iterate through all views in a document and find the view you are looking for.

FilteredElementCollector collector = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Views);
foreach (Autodesk.Revit.DB.View v in collector.ToElements())
{
    if (v && v.Name == "My Special View")
        viewId = v.Id;
}

Then you can call the API you already know with this viewId instead of doc.ActiveView.Id.

FilteredElementCollector lstEleCollector = new FilteredElementCollector (doc, viewId);
ICollection<Element> collection = lstEleCollector.OfCategory(BuiltInCategory.OST_SpecialityEquiosystem)
    .ToElements();
int count = collection.Count;

Also refer our very basic forge-countdeletewalls-revit code sample which does something similar to what you are attempting. It counts walls, doors, floors and windows in a given document.
