Question

我正在尝试使用PromptForFamilyInstancePlacement放置详细信息组件，但无法正确定义FamilySymbol。

我找到的示例显示如何使用FilteredElementCollector，但我尝试按名称定义FamilySymbol。

Answer 1

您是否已将Family文档加载到您正在使用的项目中？如果没有，则可以使用Document.LoadFamilySymbol或Document.LoadFamily将系列加载到项目中。否则，要找到您要查找的系列符号，您可以使用类似于以下代码的内容：

UIApplication application = commandData.Application;
UIDocument uiDocument = application.ActiveUIDocument;
Document document = application.ActiveUIDocument.Document;

FilteredElementCollector familyCollector = new FilteredElementCollector(document);
familyCollector.OfClass(typeof(FamilySymbol));

FamilySymbol familySymbolToFind = null;

foreach (FamilySymbol familySymbol in familyCollector)
{
  //To search by FamilySymbol name
  if (familySymbol.Name == "[Name of FamilySymbol to find]")
    familySymbolToFind = familySymbol;
  //To search by Family name
  else if (familySymbol.Family.Name = "[Name of Family to find]")
    familySymbolToFind = familySymbol;
}

uiDocument.PromptForFamilyInstancePlacement(familySymbolToFind);

Answer 2

尝试此代码（需要System.Linq）和.NET4

FamilySymbol symbol = GetElements<FamilySymbol>(commandData.Application.ActiveUIDocument.Document)
                          .Where(item => item.Name == "NameYouWant")
                          .First();
commandData.Application.ActiveUIDocument.PromptForFamilyInstancePlacement(symbol);


    /// <summary>
    /// Get the collection of elements of the specified type.
    /// <para>The specified type must derive from Element, or you can use Element but you get everything :)</para>
    /// </summary>
    /// <typeparam name="T">The type of element to get</typeparam>
    /// <returns>The list of elements of the specified type</returns>
    public IEnumerable<T> GetElements<T>(Document document) where T : Element
    {
        FilteredElementCollector collector = new FilteredElementCollector(document);
        collector.OfClass(typeof(T));
        return collector.Cast<T>();
    }

Answer 3

它们都有效，即使在Revit 2017中也是如此。（在第二个解决方案中，如果行需要==而不是=，则为else。）

在第二个解决方案中，我使用它来确保我有正确的姓氏和家庭符号名称：

foreach (FamilySymbol familySymbol in familyCollector)
{
  if (familySymbol.Name == "Put your Family Name here" && familySymbol.Family.Name == "Put your Family Symbol Name here")
                        familySymbolToFind = familySymbol;
}
