Revit API-从Revit项目FamilyDelete.pushbutton中完全删除系列

Question

我在尝试从项目中删除家庭时遇到问题。我可以删除族类型，但似乎族仍在项目中加载。有没有办法将其完全删除？

到目前为止，我已经查看了以下来源：

2）https://adndevblog.typepad.com/aec/2012/07/supported-workflow-for-unloading-a-family-using-the-revit-api.html

这是我的代码：

FilteredElementCollector colTitleBlocks = new FilteredElementCollector(doc)
                .OfClass(typeof(FamilySymbol))
                .OfCategory(BuiltInCategory.OST_TitleBlocks);


using (Transaction tx6 = new Transaction(doc))
{
    tx6.Start("load custom titleblock that you just made");


    Element family2Unload = null;
    foreach (FamilySymbol xfamily in colTitleBlocks )
        {

        if (xfamily.FamilyName == "E1 30 x 42 Horizontal")
             {

             family2Unload = doc.GetElement(xfamily.Id) as Element;

             }
        }
   doc.Delete(family2Unload.Id);

   tx6.Commit();
}

Answer 1

家庭

[FamilyInstance =>家庭的一个放置实例

FamilySymbol =>具有0-m个实例的族类型

[Family =>一个具有n个类型0-m实例的族

示例：FamilyDelete.pushbutton

这是我从pyRevitMEP中删除家庭的脚本之一：
