创建链接模型标注

创建Floor等有实体形状的标注

今天在回答Revit API Forum的问题的时候发现一个问题，如何获取链接模型的reference从而实现标注Reference to Grid and Level from link，我便使用CreateLinkReference(doc)这个方法直接获取，结果创建dimension失败
报错有无效的reference，后来debug直接获取手动创建的link reference成功标注，觉得是获取的reference的问题，后台查阅refernce的strign字符串发现不一致


后来看到这篇文章[Revit处理链接文件标注Reference](https://blog.csdn.net/qq_40430656/article/details/122101018)，修改后创建dimension成功，应该是转换的refernce-stable出现问题所以直接获取创建失败。

var floor = RevitCommandData.Document.GetElement(5676918) as Floor;
            var reference = floor.GetTopFaceReferences().First();

            var linkInstance = RevitCommandData.Document.GetElement(5678360) as RevitLinkInstance;
            var linkDoc = linkInstance.GetLinkDocument();
            var targetLinkEle = linkDoc.GetElement(5677607) as Floor;
            var linkFace =
                targetLinkEle.GetGeometryObjectFromReference(HostObjectUtils.GetTopFaces(targetLinkEle).First()) as
                    Face;
            var linkRef = HostObjectUtils.GetTopFaces(targetLinkEle).First().CreateLinkReference(linkInstance);
            var str = linkRef.ConvertToStableRepresentation(RevitCommandData.Document);
            var str2 = referenceLink.ConvertToStableRepresentation(RevitCommandData.Document);
            var strs = str.Split(':').ToList();
            var newStr = $"{strs[0]}:0:RVTLINK:{strs[2]}:{strs[3]}:{strs[4]}";
            var newReference = Reference.ParseFromStableRepresentation(RevitCommandData.Document, newStr);
            var testRef = newReference.ConvertToStableRepresentation(RevitCommandData.Document);
          
            TransactionUtils.Execute(RevitCommandData.Document,new Action<IDisposable>(x =>
            {
                var referenceArray = new ReferenceArray();
                referenceArray.Append(reference);
                referenceArray.Append(newReference);
                var fakeLine = Line.CreateUnbound(new XYZ(-49.469472958128, 1769.33005941939, 209.147513214079),
                    -XYZ.BasisZ);
                var dim = RevitCommandData.Document.Create.NewDimension(RevitCommandData.ActiveView, fakeLine,
                    referenceArray);
            }),"test");

创建Level Grid等没有实体形状的标注
