[Revit API , CSharp]
Hi everyone, I hope you will help me!!
My code:

public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
try
{
// Display WPF Form
// _wpfWindowController.ShowForm(commandData.Application);
doc = commandData.Application.ActiveUIDocument.Document;
DimensionType dimensionType = new FilteredElementCollector(doc).OfClass(typeof(DimensionType)).Cast<DimensionType>().FirstOrDefault();
Grid gridperH = doc.GetElement(new ElementId(419358)) as Grid;
FamilyInstance ins = doc.GetElement(new ElementId(419291)) as FamilyInstance;
XYZ loc = (ins.Location as LocationPoint).Point;
Line line = Line.CreateBound(loc + XYZ.BasisY, loc + XYZ.BasisY + XYZ.BasisX);
// Dimension OK
FamilyInstance insSingle = doc.GetElement(new ElementId(422010)) as FamilyInstance;
ReferenceArray referenceArr = new ReferenceArray();
referenceArr.Append(GetReferenceFromGrid(gridperH));
referenceArr.Append(GetCurveCenterFamilyInstance(insSingle));
DimensionTest(line, referenceArr);
// Dimension Sub Element : Error
referenceArr = new ReferenceArray();

(k.GetEndPoint(0).DistanceTo(new XYZ(0, 0, k.GetEndPoint(0).Z)) <= 0.0001 || k.GetEndPoint(1).DistanceTo(new XYZ(0, 0, k.GetEndPoint(1).Z)) <= 0.0001))
.FirstOrDefault();
return (curveOrigin.GetEndPoint(0).DistanceTo(XYZ.Zero) < curveOrigin.GetEndPoint(1).DistanceTo(XYZ.Zero)) ? curveOrigin.GetEndPointReference(0) : curveOrigin.GetEndPointReference(1);
}

}

{
List<Curve> lstRes = new List<Curve>();
// get references
foreach (var geo in geoEle)
{
GeometryInstance geoIns = geo as GeometryInstance;
if (geoIns != null)
{
GeometryElement newGeo = IsGetGeometryInstance == true ? geoIns.GetInstanceGeometry() : geoIns.GetSymbolGeometry();
if (newGeo != null)
{
List<Curve> lst = GetCurvesGeoElement(newGeo, IsGetGeometryInstance);
if (lst.Count > 0)
{
lstRes.AddRange(lst);
}
}
}
Curve curve = geo as Curve;
if (curve != null)
{
lstRes.Add(curve);
}
}
return lstRes;
}
}
}My problem is as follows:
- (id=422101): If I dim the familyInstance object, it runs normally
- (id=419291): But since I dim familyInstance is a sub element then it doesn't work!
------ family (419291) = Family (422010)

[If there are examples, the better!!]
Thanks you very much!!!
