如何引用链接文档中的Reference在主文档中创建尺寸标注？
思路：我想通过调用Revit的API。在主文档中的平面视图下选择一面链接文件中的墙，捕获到墙边界的面的Refernce。然后完成尺寸的标注。
问题：通过API获取到链接文档，然后获取到墙在链接文档中的Refernce后，无法引用这些Refernce在当前文档中实现标注。提示错误如下：
代码如下：
public class 链接文件墙洞口标注 : IExternalCommand
{
public class WallSelectionFilter : ISelectionFilter
{
public RevitLinkInstance instance = null;
public bool AllowElement(Element elem)
{
instance = elem as RevitLinkInstance;
if (instance != null)
{
return true;
}
return false;
}
public bool AllowReference(Reference reference, XYZ position)
{
if (instance == null)
{
return false;
}
else
{
Document linkdocument = instance.GetLinkDocument();
Element ent = linkdocument.GetElement(reference.LinkedElementId);
return ent is Wall;
return false;
}
}
}
private void AddCurvesAndSolids(GeometryElement geomElem, CurveArray curves, List<Solid> solids)
{
foreach (GeometryObject geomObject in geomElem)
{
Solid solid = geomObject as Solid;
if (null != solid)
{
solids.Add(solid);
continue;
}
//如果GeometryObject 是几何实例，则进行二次遍历
GeometryInstance geomInst = geomObject as GeometryInstance;
if (null != geomInst)
{
AddCurvesAndSolids(geomInst.GetSymbolGeometry(geomInst.Transform), curves, solids);
}
}
}
public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
#region 建立revit连接

#endregion

Document lincdoc = linkInstance.GetLinkDocument();
Element ent = lincdoc.GetElement(ref1.LinkedElementId);
Wall wallent = null;
wallent = ent as Wall;
Transaction trans = new Transaction(doc);
trans.Start("sta");
LocationCurve lc = wallent.Location as LocationCurve;
Curve curve = lc.Curve;
Line line1 = curve as Line;

}求大神告诉我，我该怎样去引用墙的Refernce。才能完成这个标注呢？
