Revit API - 从 Revit 项目中完全删除族

Question

我运行在尝试从项目中删除家庭时遇到了问题。我可以删除族类型，但该族似乎仍在项目中加载。有没有办法完全删除它？

到目前为止，我查看了这些来源：

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 => 已放置的家族实例

FamilySymbol => 具有 0-m 个实例的族类型

Family => 具有 n 类型 0-m 实例的家族

示例：FamilyDelete.pushbutton

这是我 pyRevitMEP 用来删除家庭的脚本之一：
